The history of the Israeli–Palestinian conflict traces back to the late 19th century when Zionists sought to establish a homeland for the Jewish people in Ottoman-controlled Palestine, a region roughly corresponding to the Land of Israel in Jewish tradition. The Balfour Declaration of 1917, issued by the British government, endorsed the idea of a Jewish homeland in Palestine, which led to an influx of Jewish immigrants to the region. Following World War II and the Holocaust, international pressure mounted for the establishment of a Jewish state in Palestine, leading to the creation of Israel in 1948.
The establishment of Israel, and the war that followed and preceded it, led to a major demographic change in the form of displacement of hundreds of thousands of Palestinians.
