Mandatory Palestine was a geopolitical entity established by the League of Nations after World War I. It was governed by the British Empire from 1920 to 1948, following the defeat of the Ottoman Empire. The mandate aimed to prepare the region for self-governance while addressing the conflicting national aspirations of the Jewish and Arab populations. During this period, significant events occurred, including increased Jewish immigration and the rise of nationalist movements. Tensions between the Jewish and Arab communities escalated, leading to violence and political strife. The mandate ended in 1948, paving the way for the establishment of the State of Israel.
