1941 marked an escalation of the Second World War in Europe. By the middle of the year, Germany and its European allies had already consolidated power across most of the continent, with only the United Kingdom and Soviet Union not under Axis control or on neutral terms with Germany. As population sizes were fundamental to the war effort, both in terms of military manpower and the workforce of the home front, the annexation of other countries proved vital in supplying new volunteers, conscripts, and forced laborers for the Axis war effort. Together, Germany and Austria had a similar population to the rest of Europe's Axis powers combined, with all giving a total population of 154 million. However, the total population of the Axis-occupied territories in Europe was comparable to the Axis home fronts themselves, at almost 130 million people

Germans in the East Eastern Europe had a sizeable population of ethnic Germans who often worked with the Axis powers, and the German Army recruited upwards of a million volunteers from occupied countries. The Soviet Union in particular had a number of Russia German enclaves across the region, that reached as far as the Volga river and Kazakhstan and numbered at several million people. In Russia, these communities had existed for centuries, but they were ostracized or mistrusted by Soviet leadership and the deaths of these communities under Stalin's regime is often considered genocide. In addition to ethnic Germans, collaborators also included large numbers of Eastern Europeans who sympathized with Nazi ideology, or were hostile to Soviet or communist expansion; this also included ethnic minorities, such as Muslims from the Balkans or USSR.

Collaborators in the West The perceived threat of communism in the west saw men volunteer from countries such as France, the Netherlands, or Norway, to fight in the Axis armies. The fluctuating borders of the interwar period also meant that there were many German communities across the borders of neighboring countries, whose men also enlisted in the Wehrmacht. Within these occupied countries, conspirators with local knowledge were used to track down Jews and political adversaries, and many collaborated in order to elevate their positions in the government or enterprises. Apart from Austria, however, the majority of the public in annexed territories were unsupportive or hostile to their occupiers, and after the war, many of the surviving collaborators were tried (and often executed) for their actions.

In 1800, the region of Germany was not a single, unified nation, but a collection of decentralized, independent states, bound together as part of the Holy Roman Empire. This empire was dissolved, however, in 1806, during the Revolutionary and Napoleonic eras in Europe, and the German Confederation was established in 1815. Napoleonic reforms led to the abolition of serfdom, extension of voting rights to property-owners, and an overall increase in living standards. The population grew throughout the remainder of the century, as improvements in sanitation and medicine (namely, mandatory vaccination policies) saw child mortality rates fall in later decades. As Germany industrialized and the economy grew, so too did the argument for nationhood; calls for pan-Germanism (the unification of all German-speaking lands) grew more popular among the lower classes in the mid-1800s, especially following the revolutions of 1948-49. In contrast, industrialization and poor harvests also saw high unemployment in rural regions, which led to waves of mass migration, particularly to the U.S.. In 1886, the Austro-Prussian War united northern Germany under a new Confederation, while the remaining German states (excluding Austria and Switzerland) joined following the Franco-Prussian War in 1871; this established the German Empire, under the Prussian leadership of Emperor Wilhelm I and Chancellor Otto von Bismarck. 1871 to 1945 - Unification to the Second World War The first decades of unification saw Germany rise to become one of Europe's strongest and most advanced nations, and challenge other world powers on an international scale, establishing colonies in Africa and the Pacific. These endeavors were cut short, however, when the Austro-Hungarian heir apparent was assassinated in Sarajevo; Germany promised a "blank check" of support for Austria's retaliation, who subsequently declared war on Serbia and set the First World War in motion. Viewed as the strongest of the Central Powers, Germany mobilized over 11 million men throughout the war, and its army fought in all theaters. As the war progressed, both the military and civilian populations grew increasingly weakened due to malnutrition, as Germany's resources became stretched. By the war's end in 1918, Germany suffered over 2 million civilian and military deaths due to conflict, and several hundred thousand more during the accompanying influenza pandemic. Mass displacement and the restructuring of Europe's borders through the Treaty of Versailles saw the population drop by several million more.

Reparations and economic mismanagement also financially crippled Germany and led to bitter indignation among many Germans in the interwar period; something that was exploited by Adolf Hitler on his rise to power. Reckless printing of money caused hyperinflation in 1923, when the currency became so worthless that basic items were priced at trillions of Marks; the introduction of the Rentenmark then stabilized the economy before the Great Depression of 1929 sent it back into dramatic decline. When Hitler became Chancellor of Germany in 1933, the Nazi government disregarded the Treaty of Versailles' restrictions and Germany rose once more to become an emerging superpower. Hitler's desire for territorial expansion into eastern Europe and the creation of an ethnically-homogenous German empire then led to the invasion of Poland in 1939, which is considered the beginning of the Second World War in Europe. Again, almost every aspect of German life contributed to the war effort, and more than 13 million men were mobilized. After six years of war, and over seven million German deaths, the Axis powers were defeated and Germany was divided into four zones administered by France, the Soviet Union, the UK, and the U.S.. Mass displacement, shifting borders, and the relocation of peoples based on ethnicity also greatly affected the population during this time. 1945 to 2020 - Partition and Reunification In the late 1940s, cold war tensions led to two distinct states emerging in Germany; the Soviet-controlled east became the communist German Democratic Republic (DDR), and the three western zones merged to form the democratic Federal Republic of Germany. Additionally, Berlin was split in a similar fashion, although its location deep inside DDR territory created series of problems and opportunities for the those on either side. Life quickly changed depending on which side of the border one lived. Within a decade, rapid economic recovery saw West Germany become western Europe's strongest economy and a key international player. In the east, living standards were much lower, although unemployment was almost non-existent; internationally, East Germany was the strongest economy in the Eastern Bloc (after the USSR), though it eventually fell behind the West by the 1970s. The restriction of movement between the two states also led to labor shortages in t...

It is estimated that, in 1933, just 0.77 percent of the German population was Jewish. Despite this, Nazi leaders and propaganda perpetually claimed that Jews owned up to 20 percent of all capital in the German economy, and used claims such as this to demonize Jews and turn the rest of German society against the Jewish community. Official estimates from the national statistical office or central bank in the 1930s, as well as some modern estimates, also suggest that Jewish wealth may have been equal to as much as 20 percent of national wealth; however, this is misrepresentative.

According to a 2019 paper by Albrecht Ritschl of the London School of Economics, the share of Jewish-owned assets in the private sector alone was actually much lower. Ritschl uses a range of estimates (two potential figures for the German total, and three potential figures for the Jewish total) to show that the Jewish share of capital in the private sector in 1937 was likely somewhere between 0.96 and 1.57 percent. The author claims that the middle estimates, where Jewish assets are valued at 3.54bn RM, is likely the most plausible. It is also estimated that the combined capital in the public and private sector was around 400 billion RM, and if one uses the estimate of Jewish assets being valued at 2.99 billion, then this is equal to a 0.75 percent, which is almost the exact same as their population share in 1933. The paper then concludes that the share of Jewish assets in the German economy was much more in line with their population size than the bogus claims made by Nazi leaders, propaganda, and the German media.

Most estimates place the total number of deaths during the Second World War at around 70-85 million people. Approximately 17 million of these deaths (20-25 percent of the total) were due to crimes against humanity carried out by the Nazi regime in Europe. In comparison to the millions of deaths that took place through conflict, famine, or disease, these 17 million stand out due to the reasoning behind them, along with the systematic nature and scale in which they were carried out. Nazi ideology claimed that the Aryan race (a non-existent ethnic group referring to northern Europeans) was superior to all other ethnicities; this became the justification for German expansion and the extermination of others. During the war, millions of people deemed to be of lesser races were captured and used as slave laborers, with a large share dying of exhaustion, starvation, or individual execution. Murder campaigns were also used for systematic extermination; the most famous of these were the extermination camps, such as at Auschwitz, where roughly 80 percent of the 1.1 million victims were murdered in gas chambers upon arrival at the camp. German death squads in Eastern Europe carried out widespread mass shootings, and up to two million people were killed in this way. In Germany itself, many disabled, homosexual, and "undesirables" were also killed or euthanized as part of a wider eugenics program, which aimed to "purify" German society.

The Holocaust Of all races, the Nazi's viewed Jews as being the most inferior. Conspiracy theories involving Jews go back for centuries in Europe, and they have been repeatedly marginalized throughout history. German fascists used the Jews as scapegoats for the economic struggles during the interwar period. Following Hitler's ascendency to the Chancellorship in 1933, the German authorities began constructing concentration camps for political opponents and so-called undesirables, but the share of Jews being transported to these camps gradually increased in the following years, particularly after Kristallnacht (the Night of Broken Glass) in 1938. In 1939, Germany then invaded Poland, home to Europe's largest Jewish population. German authorities segregated the Jewish population into ghettos, and constructed thousands more concentration and detention camps across Eastern Europe, to which millions of Jews were transported from other territories. By the end of the war, over two thirds of Europe's Jewish population had been killed, and this share is higher still when one excludes the neutral or non-annexed territories.

Lebensraum Another key aspect of Nazi ideology was that of the Lebensraum (living space). Both the populations of the Soviet Union and United States were heavily concentrated in one side of the country, with vast territories extending to the east and west, respectively. Germany was much smaller and more densely populated, therefore Hitler aspired to extend Germany's territory to the east and create new "living space" for Germany's population and industry to grow. While Hitler may have envied the U.S. in this regard, the USSR was seen as undeserving; Slavs were the largest major group in the east and the Nazis viewed them as inferior, which was again used to justify the annexation of their land and subjugation of their people. As the Germans took Slavic lands in Poland, the USSR, and Yugoslavia, ethnic cleansings (often with the help of local conspirators) became commonplace in the annexed territories. It is also believed that the majority of Soviet prisoners of war (PoWs) died through starvation and disease, and they were not given the same treatment as PoWs on the western front. The Soviet Union lost as many as 27 million people during the war, and 10 million of these were due to Nazi genocide. It is estimated that Poland lost up to six million people, and almost all of these were through genocide.

The Holocaust was the systematic extermination of Europe's Jewish population in the Second World War, during which time, up to six million Jews were murdered as part of Nazi Germany's "Final Solution to the Jewish Question". In the context of the Second World War, the term "Holocaust" is traditionally used to reference the genocide of Europe's Jews, although this coincided with the Nazi regime's genocide and ethnic cleansing of an additional eleven million people deemed "undesirable" due to their ethnicity, beliefs, disability or sexuality (among others). During the Holocaust, Poland's Jewish population suffered the largest number of fatalities, with approximately three million deaths. Additionally, at least one million Jews were murdered in the Soviet Union, while Hungary, Latvia, Lithuania, the Netherlands and Yugoslavia also lost the majority of their respective pre-war Jewish populations. The Holocaust in Poland In the interwar period, Europe's Jewish population was concentrated in the east, with roughly one third living in Poland; this can be traced back to the Middle Ages, when thousands of Jews flocked to Eastern Europe to escape persecution. At the outbreak of the Second World War, it is estimated that there were 3.4 million Jews living in Poland, which was approximately ten percent of the total population. Following the German invasion of Poland, Nazi authorities then segregated Jews in ghettos across most large towns and cities, and expanded their network of concentration camps throughout the country. In the ghettos, civilians were deprived of food, and hundreds of thousands died due to disease and starvation; while prison labor was implemented under extreme conditions in concentration camps to fuel the German war effort. In Poland, six extermination camps were also operational between December 1941 and January 1945, which saw the mass extermination of approximately 2.7 million people over the next three years (including many non-Poles, imported from other regions of Europe). While concentration camps housed prisoners of all backgrounds, extermination camps were purpose-built for the elimination of the Jewish race, and over 90% of their victims were Jewish. The majority of the victims in these extermination camps were executed by poison gas, although disease, starvation and overworking were also common causes of death. In addition to the camps and ghettos, SS death squads (Einsatzgruppen) and local collaborators also committed widespread atrocities across Eastern Europe. While the majority of these atrocities took place in the Balkan, Baltic and Soviet regions, they were still prevalent in Poland (particularly during the liquidation of the ghettos), and the Einsatzgruppen alone are estimated to have killed up to 1.3 million Jews throughout the Holocaust. By early 1945, Soviet forces had largely expelled the German armies from Poland and liberated the concentration and extermination camps; by this time, Poland had lost roughly ninety percent of its pre-war Jewish population, and suffered approximately three million further civilian and military deaths. By 1991, Poland's Jewish population was estimated to be just 15 thousand people, while there were fewer than two thousand Jews recorded as living in Poland in 2018.

On November 10, 1938, just two days after the Kristallnacht pogroms, the German government introduced the Judenvermögensabgabe; the Jewish capital levy. Jews with more than 5,000 Reichsmarks (RM) in assets were required to pay a 20 percent tax on all assets in order to meet a collective target of one billion RM. Despite inflated claims of Jewish wealth, the events of the preceding five years had financially crippled many of Germany's Jewish population, and it quickly became clear that the target sum would not be met, therefore the tax was increased to 25 percent in 1939. Jewish property This levy was introduced by Herman Göring, as a punishment for Jews and their so-called "hostile attitude" towards the German people. In reality, funds from the levy were to be used to repair the businesses damaged in the pogroms (the cost of which was estimated to be 225 million RM), which were then seized by the government and sold on to non-Jewish buyers. Many of these properties were confiscated through two additional decrees in 1938, which also saw authorities force Jewish businesses to sell selected assets at severely reduced prices. Deportation A clause of the Nuremberg Laws of 1936 stripped overseas German Jews of their citizenship and property; this rule was then applied to the thousands of German Jews who were deported to concentration and extermination camps in Eastern Europe after 1941. The remaining Jewish assets were seized by the Nazi regime and put towards the war effort, which ultimately included the systematic murder of many German Jews.

The worldwide Jewish population experienced a marked decline during the 20th century due to the murder of six million Jewish people during the Holocaust, the genocide perpetrated by Nazi Germany and its allies during World War II. While there were almost 17 million Jewish people alive before the Holocaust, or the Shoah as it is known in Hebrew, after the war this was only around 11.5 million people. By using several different fertility scenarios, demographers have been able to reconstruct what the Jewish population would be in modern times if the genocide of Jewish people had not happened. In scenarios where there was a low or very low fertility rate, the Jewish population in 2000 would be in the range of 26 to 33 million people, double what it was in reality. In a scenario where the population growth rate was the same as that observed in the Jewish population after WWII, which was extremely low, the global Jewish population would have risen to over 20 million people.

In May 1941, less than two years after the German invasion of Poland, the total number of forced laborers in the German economy stood at approximately three million people. Around half of these worked in an agricultural capacity, and a third worked in industry. Over the next three years, the number increased to 7.1 million forced laborers, and the industrial sector grew to be the largest user of forced labor. Forced laborers Due to the high number of men mobilized, and a reluctance to have women to enter the workforce, the Nazi regime heavily encouraged the voluntary migration of workers from annexed territories in the early years of the war, in order to meet the labor demand of the Reich. There was a small influx of voluntary workers, but it quickly became evident that working conditions were much harsher than expected (especially for Poles), and the stream of workers dried up. In April 1940, authorities in German-annexed Poland then ordered that all available workers born between 1915 and 1925 were required to move to Germany. The largest source of forced labor, however, was from concentration camps; it was mostly Jews and Slavs, as well as other ethnic minorities, political prisoners, criminals, and prisoners of war. Between 1939 and 1944, the number of German laborers also grew substantially; the Nazi regime implemented stricter laws and sentences that punished people for any activities perceived to be critical of or in contrast to Nazi ideology (such as listening to foreign or underground radio stations), and 16 year olds were also sentenced as adults. However, Germans made up a minority of forced laborers in Germany, and this fell to just five to 10 percent of forced laborers by the war's end. Extermination through work Most forced laborers were contributing directly to the German war effort, producing food, armaments, and materiel for the front lines. Because of this, their places of work became targets for Allied bombing campaigns, which had a disproportionate effect on Germany's forced labor population. Forced laborers were then used in the active repair and rebuilding of these targeted areas, which exposed them to further raids, undetonated bombs, and chemical hazards. In later years, the share of Gypsies, Jews, and Slavs working in Germany increased further, and the living conditions for these prisoners worsened. As the Reich's resources became stretched, food and provisions for prisoners were rationed, healthcare became non-existent, and work quotas increased; it was only in mid-1944 that the authorities realized how detrimental this was to output and rations were increased. In the winter of 1944-45, as the Soviets pushed west into Germany, many of the larger concentration camps in the east were evacuated and the prisoners were sent on "death marches" to reinforce the workforce in Germany. Some estimates suggest that up to 700,000 prisoners were forced on these death marches (including 56,000 from Auschwitz in mid-January), and between 200,000 and 350,000 were killed. Despite its negative impact on production for the war effort, the extermination of ethnic minorities and so-called "undesirables" by exhaustion was still seen as an overall favorable outcome.

In late May 1939, just three months before the Second World War began in Europe, Germany's workforce was made up of almost 25 million men, 15 million women, and a very small number of foreign workers. The share of German men in the workforce decreased each year thereafter, as more were conscripted into the armed forces, and there were approximately 11 million fewer German male citizens in the workforce by September 1944. The number of German women fluctuated, but remained between 14 and 15 million throughout the given period, and it exceeded the number of German men in 1944. Despite the number of German men in the workforce dropping by 45 percent, the total number of workers in German was consistently around 36 million between 1940 and 1944, as this difference was offset by foreign and forced laborers. These workers were mostly drafted from annexed territories in Eastern Europe, and prisoners were transferred from concentration and POW camps to meet the labor demands in various areas of Germany.

The Nationalist Socialist German Workers' Party (the Nazi Party) was founded in Germany in 1920 as an extreme-right alternative to communism for working-class voters. Similarly to the Communist Party, early Nazi ideologies were largely opposed to capitalism, business elites, and the centrist political establishment, however their approach was much more nationalistic and militaristic. Throughout the 1920s, as Adolf Hitler consolidated his power and became party leader in 1925, party rhetoric shifted focus to become increasingly anti-communist and anti-Semitic, while the socialist element was gradually erased. With the onset of the Great Depression in 1930, the Party saw its popularity increase and it grew to become the largest political party in July 1932, before Hitler assumed power in January of the following year. Early election performance As a new party whose presence was largely concentrated in Bavaria, the Nazi Party performed reasonably well in their first federal election, taking around seven percent of the nationwide vote. This success was largely in response to the perceived failures of the German political class following defeat in the First World War and their adherence to the Treaty of Versailles, as well as the hyperinflation crisis in the postwar years. Despite this, they were still considered a fringe party by most, and received around half of the number of votes of their communist rivals. As the economy began recovering in mid-1924, the Nazi Party saw their popularity wane, and they received just three percent of the vote in the subsequent two elections. Nazi ascension After the 1928 election, Germany was ruled by a so-called "Grand Coalition" of four traditional political parties. When the Great Depression began, Germany was one of the hardest-hit economies in the world, and the Nazi Party used this as an opportunity to draw voters away from the Grand Coalition. Voters were drawn for a variety of reasons, such as voting for radical change in the face of economic disaster, support for increased militarism and police enforcement, or because they agreed with anti-Semitic and racist ideologies. A common misconception is that the Nazi Party's success was due to support from the urban working class, however evidence shows that rural or small-town populations and the middle class (particularly small business owners) made up the core of the Nazi voter base. As support for the Communist Party also grew, many business leaders threw their support behind the Nazi Party, and it became the largest party in the Reichstag in July 1932. Becoming a dictatorship The leader of the largest party was traditionally named Chancellor of Germany, but President Von Hindenburg withheld from appointing Hitler until January 31, 1933. On February 27, an arson attack on the Reichstag parliament building was (supposedly) carried out by a Dutch communist, which the Nazi Party then used as a basis to attack its political opponents and hold yet another election on March 6. The election saw the Nazi Party increase their presence in parliament (although they did not achieve a majority), while the Reichstag Fire Decree and the Enabling Act were implemented as a result of the attack, and gave sweeping powers to the Nazi Party. Communist gatherings were de facto banned, up to 10,000 political opponents were arrested within two weeks of the fire, and the first concentration camp was opened at Dachau to house these prisoners. These measures would become a large part of the legal foundation of Hitler's dictatorship, and inspire the concentration camp system used during the Holocaust. The election of 1933 would be the last multi-party election held in all of Germany until the 1990s, as all new and existing parties were outlawed in July 1934. The three federal elections held between 1933 and 1938 were sham elections, with the Nazi Party members (and some chosen "guests") being the only candidates on the ballot.

The German state’s persecution of the Jews escalated following Hitler’s ascent to power in 1933. While the Holocaust ultimately resulted in the Nazi regime murdering two thirds of Europe’s Jewish population, a large part of the pre-Holocaust persecution involved the financial ruination of Germany’s Jews. After assuming power, the Nazis then coerced Jews into fleeing the country, stripping them of their wealth in the process.

Reichsfluchtsteuer During the Great Depression, the Weimar Republic introduced an emigration tax in order to prevent wealthy individuals from taking their capital abroad. Originally, those with assets exceeding a value of 200,000 Reichsmarks (RM) or those who earned over 20,000 RM per year would be taxed 25 percent of all assets over a certain value if they wished to move abroad. This law was introduced as a short term measure in 1931, set to expire one year later, but it was extended until 1934. When the Nazi Party rose to power in 1933, they repeatedly restricted and extended this law, and lowered the threshold of asset worth to 50,000 RM in 1934. This coincided with the widespread boycott of Jewish businesses, as well as an escalation of violence, intimidation, and restrictions aimed at Jews; therefore, any Jew wishing to flee persecution in Germany would be forced to give up a large share of their assets to the government.

In practice Following the taxation of assets in Germany, the remaining values were to be transferred to the emigrant in their destination country. This process was done through the German Central Bank, and authorities adopted an official policy of suspicion when dealing with Jews, and the sums taken were much higher than the official tax rates. The emigration tax was used as a means of seizing additional assets from Jewish emigrants, and it is estimated that in 1937 alone, the final amount transferred abroad was worth just 7.5 percent of the original value. In total, over one billion RM of assets was declared by German emigrants between 1933 and 1937, and 250 million was taken as emigration tax, but an additional 530 million was seized or frozen by the state. Although these laws applied to all German emigrants at the time, it is estimated that over 90 percent of the funds were taken from Jews and other persecuted minorities.

Europe's Jewish population in 1939 was around 9.5 million people, and it is estimated that six million of these were ultimately killed by 1945. The persecution of German Jews escalated during the interwar period, particularly after Hitler's ascent to power in 1933, and again after Kristallnacht in 1938. However, the scale of this increased drastically following the German invasions of Poland in 1939 and the USSR in 1941, when Germany annexed regions with some of the largest Jewish populations in Europe. Extermination Camps As part of the "Final Solution to the Jewish Question", the Nazi occupiers established six extermination camps in present-day Poland; these were Auschwitz-Birkenau, Belzec, Chelmno, Majdanek***, Sobibor, and Treblinka. Prisoners, mostly Jews, were transported from all over Europe to these camps. Upon arrival, the majority of victims were sent directly to purpose-built chambers or vans, where they were murdered with carbon monoxide or Zyklon B gas. A relatively small number of prisoners were also forced to dispose of the victims' bodies, which often included their own family members, friends, or persons known to them. Most of the deceased were incinerated, and many of the camp records were destroyed; this means that precise figures for the number of deaths in extermination camps will never be known. It has been estimated that at least 2.7 million Jews were murdered in these six camps; over two thirds of these were killed at Auschwitz or Treblinka. Einsatzgruppen After extermination camps, the most common method of murder was through mass shootings. The majority of these shootings were not carried out by regular soldiers, but specialized task forces known as "Einsatzgruppen". Each group was just a few hundred men each, but they were responsible for some of the largest individual acts of genocide in the war. The largest of these took place at Babi Yar, near Kyiv in 1941, where almost 35,000 victims were beaten, humiliated, and then shot over a two day period. The Einsatzgruppen were most active in the annexed Soviet territories (although additional regiments were active in Poland and the Balkans), and their ranks were often bolstered by local volunteers. It has been estimated that Einsatzgruppen were responsible for the genocide of more than two million people in fewer than six years.

With the heightened threat to Germany's Jewish population following the Nazi Party's ascent to power in 1933, many German Jews chose to flee or emigrate. In 1933, Germany's Jewish population was approximately 500,000 people; by the end of the war, it is estimated that 300,000 fled the country, and 165,000 were murdered in the Holocaust. In order to flee, most Jewish emigrants from Germany had to give up the majority of their wealth to the German state, whose emigration tax and seizure of property stripped Jews of their financial assets. Destination and transit For Germany's Jewish refugees, the most common destination country was the United States, and almost half of all these refugees would arrive in the U.S. over this 12 year period. As the United States had a strict quota of 27,000 German migrants per year, many refugees were forced to enter via other countries. France was the second most common destination country, receiving 100,000 refugees. However, France was also used as a transit country for German Jews wishing to travel further afield, especially after it was annexed by Germany in 1940. This was also true for several other European countries, such as the Netherlands, which had provided protection for German Jews in the mid-1930s, before rapidly becoming very unsafe following the outbreak of war in 1939. The Frank family Possibly the most famous example of this was the story of Anne Frank and her family. Anne had been born in Frankfurt, Germany in 1929, but her family moved to the Netherlands in 1934 after Hitler came to power. The family then led a relatively comfortable and successful life in Amsterdam, with her father, Otto, founding his own businesses. When the Netherlands was invaded by the Germans in 1940, the family tried to emigrate once more; Otto had been granted a single Cuban visa in 1942, but the family was forced to go into hiding as the restrictions tightened. For the next two years, with the help of non-Jewish friends, they lived in secret in the upper floor of Otto's business premises with several other Jewish refugees, in a small space concealed behind a bookcase. In August 1944, through unknown means, the group was betrayed and then arrested by Dutch authorities, and the Frank family was sent to Auschwitz-Birkenau thereafter. Anne's mother, Edith, died of starvation in Auschwitz within five months of her capture, while Anne and her sister, Margot, died one month later after being transferred to the Bergen-Belsen camp in Germany. Otto was the sole survivor of the group. Otto's secretary, Miep Gies, had saved Anne's diary the day after the group was arrested, which she then gave to Otto; he then devoted much of the remainder of his life to the publication and promotion of his daughter's diary, which has now become one of the most famous and widely-read books in recent history. Additionally, the hiding space is now open to the public, and has become one of the Netherlands' most popular tourist museums.

By mid-1941, Axis forces had already taken control of most of mainland Europe, as well as much of Northern Africa and parts of the Middle East*. At the outbreak of Operation Barbarossa, the major European countries not under Axis control were the officially-neutral states of Ireland, Portugal, Spain, Sweden, Switzerland, and Turkey, while the Soviet Union and United Kingdom were actively at war with the Axis Powers. By mid-1941, Germany and its allies controlled an area of approximately 3.28 million square kilometers in Europe; by comparison, modern Germany covers an area of approximately 357 thousand square kilometers. Axis control of Europe From September 1938, when Germany annexed the Czech Sudetenland, until June 1941, when Germany launched its invasion of the Soviet Union, the Axis Powers spent much of their time and resources consolidating power across Europe. Countries such as Bulgaria, Hungary, Romania, and Finland aligned themselves with Germany, as did Italy, who became one of the chief aggressors around the Mediterranean and in Africa. Germany and the Soviet Union both invaded and partitioned Poland in September 1939, through the Molotov-Ribbentrop Pact of non-aggression to one-another. Germany then took Denmark and most of Norway in April 1940, before pushing into Benelux and France in May. Italy also annexed Albania in April, which was used as a launching point for its failed invasion of Greece later in the year. As Italy had failed to secure the Balkans, a joint Axis offensive then pushed into Yugoslavia and Greece in April 1941, ultimately overwhelming any resistance. However, German intervention in the south then delayed the Axis invasion of the Soviet Union by over a month; Hitler later claimed that this was the reason for Germany's failure to take Moscow before the winter months, although many historians disagree. Launch of Operation Barbarossa Germany broke their pact of non-aggression with the Soviet Union with a surprise invasion, known as Operation Barbarossa, on June 22, 1941. While Axis forces had already extended control over most of Europe by this point, Operation Barbarossa became the largest military invasion or operation in human history. When compared with German capacities in its pre-1938 borders, within a few months of the invasion, the area of land controlled by Germany had grown by a factor of six, the population by a factor of four, and its access to natural resources and energy had also grown several times larger. These increased capacities were essential in allowing Germany to continue its expansion and aggression for the years to come, before the Soviet Union and the Western Allies eventually defeated the Axis forces four years later.

The fertility rate of a country is the average number of children that women from that country will have throughout their reproductive years. In Germany in 1800, the average woman of childbearing age would have 5.4 children over the course of their lifetime. It remained around this number until the late 1820s, when it then dropped to just under five, which was a long-term effect of the Napoleonic Period in Europe. From this point until the end of the nineteenth century, Germany's fertility rate was rather sporadic, reaching it's lowest point in 1855 with an average of 4.6 births per woman, and it's highest point in 1875 (just after the foundation of the German Empire in 1871), with an average of 5.4 live births per woman. From the beginning of the twentieth century until the end of the Second World War, Germany's fertility rate dropped from around 5 children per woman in 1900, to 1.9 in 1945. The only time where the fertility rate increased was in the inter-war years. Like other countries heavily involved in the Second World War, Germany (both East and West) experienced a Baby Boom from the late 1940s to the late 1960s, however it then dropped to it's lowest point of just 1.3 children per woman by 1995, shortly after the re-unification of Germany. In recent years, Germany's fertility rate has gradually been increasing again, and is expected to reach 1.6 in 2020, its highest rate in over forty years.

Throughout the 19th century, what we know today as Poland was not a united, independent country; apart from a brief period during the Napoleonic Wars, Polish land was split between the Austro-Hungarian, Prussian (later German) and Russian empires. During the 1800s, the population of Poland grew steadily, from approximately nine million people in 1800 to almost 25 million in 1900; throughout this time, the Polish people and their culture were oppressed by their respective rulers, and cultural suppression intensified following a number of uprisings in the various territories. Following the outbreak of the First World War, it is estimated that almost 3.4 million men from Poland served in the Austro-Hungarian, German and Russian armies, with a further 300,000 drafted for forced labor by the German authorities. Several hundred thousand were forcibly resettled in the region during the course of the war, as Poland was one of the most active areas of the conflict. For these reasons, among others, it is difficult to assess the extent of Poland's military and civilian fatalities during the war, with most reliable estimates somewhere between 640,000 and 1.1 million deaths. In the context of present-day Poland, it is estimated that the population fell by two million people in the 1910s, although some of this was also due to the Spanish Flu pandemic that followed in the wake of the war.

Poland 1918-1945

After more than a century of foreign rule, an independent Polish state was established by the Allied Powers in 1918, although it's borders were considerably different to today's, and were extended by a number of additional conflicts. The most significant of these border conflicts was the Polish-Soviet War in 1919-1920, which saw well over 100,000 deaths, and victory helped Poland to emerge as the Soviet Union's largest political and military rival in Eastern Europe during the inter-war period. Economically, Poland struggled to compete with Europe's other powers during this time, due to its lack of industrialization and infrastructure, and the global Great Depression of the 1930s exacerbated this further. Political corruption and instability was also rife in these two decades, and Poland's leadership failed to prepare the nation for the Second World War. Poland had prioritized its eastern defenses, and some had assumed that Germany's Nazi regime would see Poland as an ally due to their shared rivalry with the Soviet Union, but this was not the case. Germany invaded Poland on September 1, 1939, in the first act of the War, and the Soviet Union launched a counter invasion on September 17; Germany and the Soviet Union had secretly agreed to do this with the Molotov-Ribbentrop Pact in August, and had succeeded in taking the country by September's end. When Germany launched its invasion of the Soviet Union in 1941 it took complete control of Poland, which continued to be the staging ground for much of the fighting between these nations. It has proven difficult to calculate the total number of Polish fatalities during the war, for a variety of reasons, however most historians have come to believe that the figure is around six million fatalities, which equated to almost one fifth of the entire pre-war population; the total population dropped by four million throughout the 1940s. The majority of these deaths took place during the Holocaust, which saw the Nazi regime commit an ethnic genocide of up to three million Polish Jews, and as many as 2.8 million non-Jewish Poles; these figures do not include the large number of victims from other countries who died after being forcefully relocated to concentration camps in Poland.

Post-war Poland

The immediate aftermath of the war was also extremely unorganized and chaotic, as millions were forcefully relocated from or to the region, in an attempt to create an ethnically homogenized state, and thousands were executed during this process. A communist government was quickly established by the Soviet Union, and socialist social and economic policies were gradually implemented over the next decade, as well as the rebuilding, modernization and education of the country. In the next few decades, particularly in the 1980s, the Catholic Church, student groups and trade unions (as part of the Solidarity movement) gradually began to challenge the government, weakening the communist party's control over the nation (although it did impose martial law and imprison political opponent throughout the early-1980s). Increasing civil unrest and the weakening of Soviet influence saw communism in Poland come to an end in the elections of 1989. Throughout the 1990s, Poland's population growth stagnated at around 38.5 million people, before gradually decreasing since the turn of the millennium, to 37.8 million people in 2020. This decline was mostly due to a negative migration rate, as Polish workers could now travel more freely to Western Europea...

This statistic displays public perceptions and awareness of holocaust denial, in the European Union in 2018. As findings show, the majority of the respondents thought that denying the genocide of the Jewish people is a problem in their country, with Sweden and France having the highest share, at 79 percent and 78 percent of respondents respectively.

In 2020, the names "Oświęcim/Auschwitz" were associated primarily with the place of martyrdom of the Polish nation (43 percent), and slightly less frequently with the extermination of the Jews (38 percent). During the observed period, it can be seen that more people associated this place with the Holocaust of Jews. However, one percent of respondents did not have any knowledge about Auschwitz in 2020.

During the Second World War, the German invasion of Denmark took place on April 9, 1940, as part of Operation Weserübung. The primary aim of this campaign was the annexation of Norway, as control of the Scandinavian coast protected Germany's iron supply from Sweden and gave a tactical advantage for naval operations against the UK. Heavily outmanned and outgunned, the Danish government surrendered within a few hours, and this was the least-costly German invasion of the war (not including Austria), with just 16 Danish military fatalities on the day. Overall, modern estimates suggest that more than 6,600 Danes died as a direct result of the Second World War. Roughly half of these fatalities were civilian deaths, including upwards of 1,000 sailors killed by German submarines, and over 750 resistance fighters. However a significant share of Danes were also killed in the service of both the Axis or Allied Powers.

Danes in the service of Germany Almost one third of Danish fatalities were in the service of the German military, as over 6,000 Danish military volunteered to join the German war effort on the Eastern Front, alongside an unknown number of ethnic German volunteers (possibly 2,000) from Schleswig, along the German border. Almost 500 Danes were also killed for informing or collaborating with German authorities during the occupation; most of these were killed by the resistance during the occupation, although many were also executed after the war's conclusion.

The Danish resistance and the rescue of Denmark's Jews When compared with resistance movements in other countries, the rapid annexation of Denmark and the non-removal of the Danish government by Nazi authorities resulted in the Danish movement developing more slowly. The Danish government discouraged its citizens from rising up, and the restrictions imposed by Germany were initially less severe than in many other territories. However, resistance groups (including many military personnel) quickly formed and relayed a significant amount of information to the Allies in early years, before their actions became more violent in later years. Alongside numerous sabotage and assassination missions, a major operation of the Danish resistance was the rescue of Denmark's Jewish population. In early September 1943, German diplomat Georg Ferdinand Duckwitz learned of Hitler's order to arrest and deport Denmark's Jewish population, and secretly organized their reception in Sweden, before leaking the information to Danish authorities. Just days before the order was given, the resistance, with aid from Danish authorities, Jewish leaders, and many ordinary citizens, then smuggled over 7,000 Danish Jews and their families to Sweden. Several hundred Danish Jews were ultimately transported to concentration camps, although the majority were eventually rescued by the Danish-Swedish "white bus" missions just before the war's end. More than 99 percent of Denmark's Jews would ultimately survive the Holocaust. Duckwitz was named as one of the Righteous Among the Nations by the Israeli government in 1971, however, the Danish resistance requested not to be honored individually by Yad Vashem as theirs was a collective effort.
