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.

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.

Between 1941 and early 1945, over 1.3 million people were deported to the Auschwitz concentration camp complex; approximately 1.1 million of these deportees were Jewish, and one million Jews were murdered. Auschwitz was the largest of six extermination camps constructed by the Nazi regime in Poland, as part of their "Final Solution to the Jewish Question", which sought to exterminate Europe's Jewish population.

The Holocaust in Hungary Of the 1.1 million Jews sent to Auschwitz, the most common country of origin was Hungary. Hungary had a sizeable Jewish population of around 445,000 people in 1930, but Hungary's territory grew significantly after it annexed parts of Slovakia, Romania, Ukraine, and Yugoslavia in the late-1930s, and the total Jewish population (including Christians with Jewish heritage) in the 1941 census was approximately 825,000. Compared to the Germans, Hungary's treatment of the Jews throughout the war had been much less restrictive, and its prime minister opposed deportations to concentration camps. German invasion and increasing number of deportations This changed, however, in March 1944; as the Axis forces were being pushed west out of Soviet territory; Germany then invaded Hungary to prevent them from negotiating a peace with the Allies. Thereafter, a puppet government was installed and authorities, under the leadership of Adolf Eichmann, began to round up and deport Jews to Poland. While the Nazi extermination of Jews began on a large scale in 1941, the majority of Hungary's victims were deported and murdered over an eight week period, between May and July 1944. 430,000 Jews were deported from Hungary to Auschwitz in this time; it is estimated that around 20 percent of these were selected for labor, and the remaining 80 percent were sent directly to the gas chambers. Arrivals from Hungary were so rapid that the crematoriums could not keep up with the rate of murder, and additional mass graves had to be dug while the number of trains was reduced. Eventually, as the Axis position deteriorated, Hungarian authorities ceased deportations under mounting pressure from the Allies in early July. Exact figures for Hungary's death toll in the Holocaust remain elusive, although it is estimated that over 560,000 Jews were killed from within Hungary's wartime borders (270,000 from pre-war territories), with 434,000 of these deaths taking place between May and July 1944, the majority of which at Auschwitz.

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.

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.

Of the 1.3 million people deported to the Auschwitz concentration camps during the Second World War, approximately 1.1 million were murdered. The vast majority of the deportees were Jews, who made up around 90 percent of all deaths in the camp. While a much lower number of Roma/Sinti or Soviet POWs were deported to the camp, their death rates were also exceptionally high.

See the Introduction for a quick overview of the entire collection and the contact details. There are also several documents and reports available concerning the project and this particular interview. Bystander Memories bevat in totaal 59 interviews met Nederlandse niet-joodse ooggetuigen van de jodenvervolging. Deze interviews vormen een onderdeel van een project uitgevoerd door het United States Holocaust Memorial Museum, Oral History Department, waar het valt onder de 'Europe Interview Projects: Interviews with Witnesses, Collaborators, and Perpetrators'. Naast de Nederlandse interviews zijn er ook interviews gemaakt in het (Wit)Russisch, Grieks, Macedonisch, Pools, Oekraiens, Servisch, Ests, Lets, Litouws, Moldavisch, Frans, Duits, Roemeens. De aantallen interviews per land variëren sterk. Het project is in 1996 begonnen en loopt nog steeds, zie website USHMM: http://www.ushmm.org/research/collections/oralhistory/Since 1996, United States Holocaust memorial Museum's (USHMM) Department of Oral History has conducted a documentation project to collect the testimonies of individuals who were not direct victims of the Holocaust. These interviews are with witnesses, collaborators, and perpetrators. In ten years, over 600 interviews have been conducted in the following European countries: Czech Republic, Estonia, France, Germany, Latvia, Lithuania, Moldova, The Netherlands, Poland, Romania, the Ukraine, Bosnia-Herzegovina, and Serbia. These interviews serve not only as corroboration of what Jewish victims and survivors report in their interviews and memoirs, they also create a broader understanding of the tragic events of World War II by adding the perspectives of non-Jewish populations. The Dutch interviews are accessible at DANS for scientific research only.

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.

Cet entretien a eu lieu le 16 avril 2010 à Kaunas, Lituanie, au domicile de l'interviewée. Il a été mené par Marta Craveri. L'entretien a été réalisé en russe. Il a duré 1 heure et 53 minutes. BiographieAnna Barkauskienė naît à Kaunas en 1938. Son père est ingénieur, sa mère médecin, ce qui aura une grande importance dans la suite. Elle va échapper par deux fois à une mort presque certaine. D’abord, et paradoxalement, car sa famille juive est déportée en juin 1941, quelques jours avant que les Allemands envahissent le territoire de la Lituanie et n’exterminent la population juive. Son père n’est pas envoyé dans un camp, car il est malade, et accompagne donc sa famille, qui est déportée jusqu’à l’Altaï, parmi les nombreux Lituaniens. Ils imaginent alors un long exil sur ces lieux, mettant à profit un lopin de terre pour en faire un potager qui devrait leur permettre de survivre et pallier une alimentation très déficiente. Mais ce « répit » n’en est pas un, car Staline en décide autrement, lorsqu’il ordonne de développer la pêche aux embouchures des fleuves sibériens, sur les rives glacées de l’Océan Arctique. Ainsi, à l’été 1942, sa famille est embarquée ainsi que plusieurs milliers d’autres Lituaniens, dans un convoi ferroviaire jusqu’à Irkoutsk puis dans des barges sur le fleuve Angara, puis le fleuve Lena, jusqu’à la ville de Iakoutsk. Ils doivent ensuite repartir vers l’embouchure de la Lena, sur la mer de Laptev, là où ne survivront que bien peu « d’enfants de glace », après le terrible hiver 1942-43 sur les rives de cette mer (tels Irena Ašmontaitė ou David Jozefovitch). Elle aurait eu, ainsi que sa mère et son père, de grande chance d’y mourir de faim et de froid. Mais un groupe de déportés prit l’initiative de faire la liste des spécialités présentes parmi toutes les personnes ainsi convoyées, et alla frapper aux portes des différentes administrations pour offrir leurs services. Les immenses manques en personnel, qualifié suite à la guerre, permirent alors, avec l’accord du NKVD, à 800 personnes convoyées de rester à Iakoutsk et de travailler dans des conditions bien plus acceptables pour des exilés. Ainsi la mère d’Anna devint aide-soignante, une profession bien moins qualifiée que celle qu’elle avait auparavant. Son père, affaibli, décède. Ils survécurent ainsi jusqu’à la mort de Staline, et essayèrent alors de rentrer en Lituanie. Anna et sa mère ont d’abord le droit, en 1954, de vivre à Omsk où Anna peut étudier. L’oncle d’Anna envoie, à l’instar d’autres déportés ou membres de leurs familles, de multiples requêtes auprès des diverses personnalités. La mère d’Anna espérait aussi bénéficier de la protection de personnes désormais haut placées ou reconnues, tel le président du présidium de la plus haute instance soviétique en Lituanie, Justas Paleckis, qu’elle avait soigné avant 1939, alors qu’il n’était qu’un journaliste peu visible ni reconnu. Anna est libérée en 1954, et reçoit son premier passeport, qui lui permet de rentrer à Kaunas avec sa mère quelques mois après. BiographyAnna Barkauskienė was born in Kaunas in 1938. Her father was an engineer and her mother a doctor, which turned out to be important later. Twice she escaped almost certain death. First, ironically, because her Jewish family was deported in June 1941, only days before the Germans invaded Lithuania and annihilated the Jewish population. Her father was not sent to a camp, because he was ill, but went with his family, who were deported with many other Lithuanians to the Altai. They expected to spend their years in exile there, tending a patch of land as a vegetable garden to survive and eke out the scarce food they had. But this “respite” did not last long, because Stalin had other ideas and ordered fishing to be developed in the estuaries of the Siberian rivers on the frozen coast of the Arctic Ocean. So in summer 1942, the family was put on a train to Irkutsk with thousands of other Lithuanians, and then on barges along the River Angara, and then down the River Lena to Yakutsk. They were then supposed to start off again down to the mouth of the Lena on the Laptev Sea, where only very few of the “ice children” would survive the terrible winter of 1942-1943 on the coast (among them, Irena Ašmontaitė and David Jozefovitch). She and her mother and father would have most likely died of hunger and cold by the ocean. But a group of deportees had the idea of listing the professions of the people in their convoy and went round the various government offices offering their services. The severe shortage of skilled labour as a result of the war meant that, with NKVD approval, 800 of those in the convoy were allowed to stay in Yakutsk and work in conditions the exiles found much better. Anna’s mother became a nursing assistant, well below her qualifications. Her father weakened and died. And so they survived until Stalin’s death, and then tried to return to Lithuania. Anna and her mother first gained permission in 1954 to live in...

Of the 1.3 million people deported to Auschwitz during the Holocaust, between 1941 and 1945, roughly 400,000 were made prisoner and used for forced labor, while most of the remaining 900,000 were killed on arrival. Jews made up the largest ethnic group within the registered prison population, but this was much lower than their share of total arrivals or deaths at Auschwitz. In contrast, almost all of the (non-Jewish) Poles, Roma, or Soviet POWs who arrived at the camp were registered as laborers, yet most of these still died through a variety of other factors; such as exhaustion, starvation, disease, and murder.

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...

In 1800, the population of the area of modern-day Lithuania was estimated to be just under 780,000. Lithuania’s rate of population growth would remain largely unchanged in the 19th century, as the Russian Empire would slowly but gradually develop its border regions. While large numbers of Lithuanians would emigrate west-ward (largely to the United States) between 1867 and 1868 after a famine in the country, growth would remain largely uninterrupted until the beginning of the First World War in 1912, which would see Lithuania, like much of the Baltic region, devastated as the battleground between the German and Russian Empires. As the conflict spread, those who were not made to evacuate by orders from the Russian government would face economic turmoil under German occupation, and as a result, Lithuania’s population would fall from just under 2.9 million in 1910, to under 2.3 million by 1920.

While Lithuania’s population would start to grow once more following the end of the First World War, this growth would be short-lived, as economic turmoil from the Great Depression, and later occupation and campaigns of mass extermination in the Second World War, most notably the extermination of 95 to 97 percent of the country’s Jewish population in the Holocaust, would cause Lithuania’s population growth to stagnate throughout the 1930s and 1940s. In the years following the end of the Second World War, Lithuania’s population would steadily climb, as industrialization by the Soviet Union would lead to improved economic growth and access to health, and campaigns of mass immunization and vaccination would lead to a sharp decline in child mortality. As a result, by the 1990s, Lithuania would have a population of over 3.7 million. However, Lithuania’s population would rapidly decline in the years following the dissolution of the Soviet Union in 1991, as economic crises and mass emigration from the country, paired with sharp declines in fertility, would result in a dramatic reduction in population. As a result, in 2020, Lithuania is estimated to have a population of just over 2.7 million.

Prior to 1829, the area of modern day Greece was largely under the control of the Ottoman Empire. In 1821, the Greeks declared their independence from the Ottomans, and achieved it within 8 years through the Greek War of Independence. The Independent Kingdom of Greece was established in 1829 and made up the southern half of present-day, mainland Greece, along with some Mediterranean islands. Over the next century, Greece's borders would expand and readjust drastically, through a number of conflicts and diplomatic agreements; therefore the population of Greece within those political borders** was much lower than the population in what would be today's borders. As there were large communities of ethnic Greeks living in neighboring countries during this time, particularly in Turkey, and the data presented here does not show the full extent of the First World War, Spanish Flu Pandemic and Greko-Turkish War on these Greek populations. While it is difficult to separate the fatalities from each of these events, it is estimated that between 500,000 and 900,000 ethnic Greeks died at the hands of the Ottomans between the years 1914 and 1923, and approximately 150,000 died due to the 1918 flu pandemic. These years also saw the exchange of up to one million Orthodox Christians from Turkey to Greece, and several hundred thousand Muslims from Greece to Turkey; this exchange is one reason why Greece's total population did not change drastically, despite the genocide, displacement and demographic upheaval of the 1910s and 1920s. Greece in WWII A new Hellenic Republic was established in 1924, which saw a decade of peace and modernization in Greece, however this was short lived. The Greek monarchy was reintroduced in 1935, and the prime minister, Ioannis Metaxas, headed a totalitarian government that remained in place until the Second World War. Metaxas tried to maintain Greek neutrality as the war began, however Italy's invasion of the Balkans made this impossible, and the Italian army tried invading Greece via Albania in 1940. The outnumbered and lesser-equipped Greek forces were able to hold off the Italian invasion and then push them backwards into Albania, marking the first Allied victory in the war. Following a series of Italian failures, Greece was eventually overrun when Hitler launched a German and Bulgarian invasion in April 1941, taking Athens within three weeks. Germany's involvement in Greece meant that Hitler's planned invasion of the Soviet Union was delayed, and Hitler cited this as the reason for it's failure (although most historians disagree with this). Over the course of the war approximately eight to eleven percent of the Greek population died due to fighting, extermination, starvation and disease; including over eighty percent of Greece's Jewish population in the Holocaust. Following the liberation of Greece in 1944, the country was then plunged into a civil war (the first major conflict of the Cold War), which lasted until 1949, and saw the British and American-supported government fight with Greek communists for control of the country. The government eventually defeated the Soviet-supported communist forces, and established American influence in the Aegean and Balkans throughout the Cold War. Post-war Greece From the 1950s until the 1970s, the Marshall Plan, industrialization and an emerging Tourism sector helped the Greek economy to boom, with one of the strongest growth rates in the world. Apart from the military coup, which ruled from 1967 to 1974, Greece remained relatively peaceful, prosperous and stable throughout the second half of the twentieth century. The population reached 11.2 million in the early 2000s, before going into decline for the past fifteen years. This decline came about due to a negative net migration rate and slowing birth rate, ultimately facilitated by the global financial crisis of 2007 and 2008; many Greeks left the country in search of work elsewhere, and the economic troubles have impacted the financial incentives that were previously available for families with many children. While the financial crisis was a global event, Greece was arguably the hardest-hit nation during the crisis, and suffered the longest recession of any advanced economy. The financial crisis has had a consequential impact on the Greek population, which has dropped by 800,000 in 15 years, and the average age has increased significantly, as thousands of young people migrate in search of employment.

One of the most notable symbols of the Holocaust and Nazi genocide was the serial numbers tattooed upon the forearms of the victims (or on the chest for Soviet-POWs). This system, however, was used only at the Auschwitz concentration camps, and the majority of those who arrived there were not issued a number as they were sent directly to the gas chambers and executed upon arrival. Of the 1.3 million people sent to these camps, just over 400,000 arrivals were registered. Most of the registered prisoners were chosen to perform hard labor; this resulted in registered male prisoners outnumbering women at a rate of approximately 2:1. The majority of registered prisoners were also adults, as very few children were spared. The reason that tattoos were used was due to the high rate of murder and starvation at the camps, which made it difficult to identify bodies from their appearance or clothing.
