The Balfour Declaration was a statement issued by the British government on November 2, 1917. It expressed support for the establishment of a national home for the Jewish people in Palestine, while also emphasizing that the rights of existing non-Jewish communities should not be prejudiced. This declaration was part of Britain's efforts during World War I to gain support from Jewish communities worldwide. The declaration was named after Arthur Balfour, the British Foreign Secretary at the time. It was later incorporated into the Mandate for Palestine, which was approved by the League of Nations in 1922. The Balfour Declaration is considered a significant milestone in the history of the Israeli-Palestinian conflict.
