Mandate Palestine, also known as British Palestine, was a geopolitical entity that existed from 1922 to 1948 in the Middle East. However, there are several synonyms for Mandate Palestine, including British-administered Palestine, Mandatory Palestine, and even Historical Palestine. These terms describe the same area, which includes the modern-day territories of Israel, the West Bank, and Gaza Strip. The notion of Mandate Palestine arose after the end of World War I, when the League of Nations awarded Britain a mandate to oversee the region on behalf of its inhabitants. While the term Mandate Palestine may no longer be in use, its legacy lives on in the ongoing Israeli-Palestinian conflict and the division of the region to this day.
