The Balfour Declaration was a public statement issued by the British government in 1917 during the First World War announcing support for the establishment of a “national home for the Jewish people” in Palestine then an Ottoman region with a small minority Jewish population.
The Balfour Declaration which resulted in a significant upheaval in the lives of Palestinians was issued on November 2 1917. The declaration turned the Zionist aim of establishing a Jewish state in Palestine into a reality when Britain publicly pledged to establish “a national home for the Jewish people” there.
