Bird's-eye View Of Jerusalem, Israel

The Third (1919–1923) and Fourth Aliyahs (1924–1929) brought an additional 100,000 Jews to Palestine. Finally, the rise of Nazism in the 1930s led to the Fifth Aliyah, with an influx of a quarter of a million Jews. This caused the Arab revolt of 1936–1939 and led the British to cap immigration with the White Paper of 1939. With countries around the world turning away Jewish refugees fleeing the Holocaust, a clandestine movement known as Aliyah Bet was organized to bring Jews to Palestine. By the end of World War II, the Jewish population of Palestine had increased to 33% of the total population.
Independence and first years
After 1945, Britain found itself in fierce conflict with the Jewish community, as the Haganah joined Irgun and Lehi in armed struggle against British rule. At the same time, thousands of Jewish refugees from Europe sought shelter in Palestine and were turned away or rounded up and placed in detention camps by the British. In 1947, the British government withdrew from the Mandate of Palestine, stating it was unable to arrive at a solution acceptable to both Arabs and Jews. The newly created United Nations approved the Partition Plan for Palestine (United Nations General Assembly Resolution 181) on November 29, 1947, which sought to divide the country into two states—one Arab and one Jewish. Jerusalem was to be designated an international city—a corpus separatum—administered by the UN.
The Jewish community accepted the plan, but the Arab League and Arab Higher Committee rejected it. On December 1, 1947, the Arab Higher Committee proclaimed a three-day strike, and Arab bands began attacking Jewish targets. Jews were initially on the defensive as civil war broke out, but they gradually moved onto the offensive. The Palestinian Arab economy collapsed and 250,000 Palestinian-Arabs fled or were expelled.
