The British Mandate for Palestine was a legal commission for the administration of the territory of Palestine, established by the League of Nations after World War I. It began in 1920 and aimed to prepare the region for self-governance while facilitating the establishment of a national home for the Jewish people, as outlined in the Balfour Declaration of 1917. During the mandate, tensions grew between the Jewish and Arab populations, leading to conflicts and uprisings. The British faced challenges in balancing these competing national aspirations, ultimately leading to the end of the mandate in 1948, when the state of Israel was established.
