The British Mandate was a legal commission for the administration of the territories of Palestine and Transjordan after World War I. Established by the League of Nations in 1920, it aimed to prepare these regions for self-governance. The mandate allowed Britain to govern and develop the area while addressing the needs of its diverse populations. During the mandate period, tensions grew between the Jewish and Arab communities, largely due to conflicting national aspirations. The British faced challenges in balancing these interests, leading to various uprisings and political unrest. The mandate officially ended in 1948, paving the way for the establishment of the state of Israel.
