Jews were the dominant religious group in the Israel-Palestine region at the beginning of the first millennia CE, and are the dominant religious group there today, however, there was a period of almost 2,000 years where most of the world's Jews were displaced from their spiritual homeland. Antiquity to the 20th century Jewish hegemony in the region began changing after a series of revolts against Roman rule led to mass expulsions and emigration. Roman control saw severe persecution of Jewish and Christian populations, but this changed when the Byzantine Empire adopted Christianity as its official religion in the 4th century. Christianity then dominated until the 7th century, when the Rashidun Caliphate (the first to succeed Muhammad) took control of the Levant. Control of region split between Christians and Muslims intermittently between the 11th and 13th centuries during the Crusades, although the population remained overwhelmingly Muslim. Zionism until today Through the Paris Peace Conference, the British took control of Palestine in 1920. The Jewish population began growing through the Zionist Movement after the 1880s, which sought to establish a Jewish state in Palestine. Rising anti-Semitism in Europe accelerated this in the interwar period, and in the aftermath of the Holocaust, many European Jews chose to leave the continent. The United Nations tried facilitating the foundation of separate Jewish and Arab states, yet neither side was willing to concede territory, leading to a civil war and a joint invasion from seven Arab states. Yet the Jews maintained control of their territory and took large parts of the proposed Arab territory, forming the Jewish-majority state of Israel in 1948, and acheiving a ceasefire the following year. Over 750,000 Palestinians were displaced as a result of this conflict, while most Jews from the Arab eventually fled to Israel. Since this time, Israel has become one of the richest and advanced countries in the world, however, Palestine has been under Israeli military occupation since the 1960s and there are large disparities in living standards between the two regions.

The world's Jewish population has had a complex and tumultuous history over the past millennia, regularly dealing with persecution, pogroms, and even genocide. The legacy of expulsion and persecution of Jews, including bans on land ownership, meant that Jewish communities disproportionately lived in urban areas, working as artisans or traders, and often lived in their own settlements separate to the rest of the urban population. This separation contributed to the impression that events such as pandemics, famines, or economic shocks did not affect Jews as much as other populations, and such factors came to form the basis of the mistrust and stereotypes of wealth (characterized as greed) that have made up anti-Semitic rhetoric for centuries. Development since the Middle Ages The concentration of Jewish populations across the world has shifted across different centuries. In the Middle Ages, the largest Jewish populations were found in Palestine and the wider Levant region, with other sizeable populations in present-day France, Italy, and Spain. Later, however, the Jewish disapora became increasingly concentrated in Eastern Europe after waves of pogroms in the west saw Jewish communities move eastward. Poland in particular was often considered a refuge for Jews from the late-Middle Ages until the 18th century, when it was then partitioned between Austria, Prussia, and Russia, and persecution increased. Push factors such as major pogroms in the Russian Empire in the 19th century and growing oppression in the west during the interwar period then saw many Jews migrate to the United States in search of opportunity.

In 1995, Israel had a Jewish population of approximately 4.5 million people, of whom approximately 1.75 million were born abroad. Over one million of these immigrants were born in Europe, with over 650,000 of these born in the former Soviet Union. Despite Poland having the largest Jewish population in the world in the pre-WWII years, the number of Polish Jewish migrants and descendents in Israel was relatively small in 1995 when compared to the USSR due to the impact of the Holocaust.

Outside of Europe, Morocco had the largest number of Jewish immigrants and descendents in Israel by 1995. Morocco had the largest Jewish population in the Muslim world when Israel was founded in 1948, with over 250,000 people. Many Moroccan Jews sought to emigrate to Israel at this time, but often faced resistance from authorities and local populations who believed the Jews would join in the fight against the Arab forces seeking to establish a Muslim state in Palestine. The government of Morocco then officially prohibited emigration to Israel after gaining independence from France in 1956, however this policy was reversed in 1961 whereby the Moroccan government began facilitating Jewish emigration to Israel in return for payments from Jewish organizations in the U.S. and Israel. By the 1970s, Morocco's Jewish population had fallen to less than 15 percent of its size in 1948.

Since the terrorist organization Hamas launched its attacks on Israeli soil on October 7, 2023, around 1,200 Israelis died, and 5,431 were injured. Through retaliation attacks by the Israeli armed forces against Hamas in Gaza, 61,158 Palestinians were killed, and 151,442 were injured. As of August 2025, the number of Palestinian deaths in the West Bank was 955, due to the on going conflict. Information on the data situation Data on the number of fatalities and injuries are based on the UNOCHA (United Nations Office for the Coordination of Humanitarian Affairs) reporting by both parties to the conflict. The respective data sources were named for the purpose of transparency. It must be stated that in the case of wars and other conflicts, objective data collection is almost impossible, and reports are based on estimates. At the same time, it needs to be noted that some parties to the conflict may use numbers and data selectively for their own agenda. Hamas attacks on Israel on October 7th, 2023 Before October 2023, there had been four wars between Israel and Hamas. The current conflict is already the deadliest, and the death toll is certain to rise. The new escalation of violence in the Middle East started after the militant Palestinian group Hamas attacked Israel in the early hours of October 7, 2023. An estimated 2,200 rockets were fired by Hamas from Gaza toward Israeli targets, hitting civilian buildings and military facilities. Hamas fighters entered the Israeli territory, killing around 1,200 of Israeli citizens. In the weeks that followed, the Israeli military conducted an aerial bombardment and launched a ground offensive in Gaza. Humanitarian pauses allowed aid to get into Gaza, but fighting has continued since a weeklong cease-fire ended on December 1, 2023. Operation Iron Swords and the humanitarian situation of Gaza Initially, Israel reacted to the Hamas attacks with further isolation of the Gaza Strip, cutting off the supply of electricity, fuel, and drinking water. As of November 6, 2023, water supply to parts of the Gaza Strip has been resumed. The Israeli Defense Forces (IDF) summoned the Palestinians to evacuate the northern part of the Gaza Strip towards the south of Gaza in the direction of the Egyptian border. This affects around 1.93 million people out of the 2.06 million inhabitants of Gaza. According to the UN, over one million people are internally displaced inside the Gaza Strip. Some trucks with relief supplies could infrequently enter the territory via the Rafah border from Egypt. This Israeli military operation is one of the longest-lasting in Gaza, and over 6,000 bombs were already dropped by the IDF.
