Israel is located in a region known as the Land of Israel, synonymous with the Palestine region, the Holy Land, and Canaan. In antiquity it was home to the Canaanite civilisation, followed by the kingdoms of Israel and Judah. Situated at a continental crossroad, the region experienced demographic changes under the rule of empires from the Romans to the Ottomans. European antisemitism in the late 19th century galvanised Zionism, which sought a Jewish homeland in Palestine and gained British support. After World War I, Britain occupied the region and established Mandatory Palestine in 1920. Increased Jewish immigration in the lead-up to the Holocaust and British foreign policy in the Middle East led to intercommunal conflict between Jews and Arabs, which escalated into a civil war in 1947 after the United Nations (UN) proposed partitioning the land between them.
