Balfour Declaration, a British policy statement made in 1917 concerning Palestine. It reads:

His Majesty's Government view with favor the establishment in Palestine of a national home for the Jewish people, and will use their best endeavors to facilitate the achievement of that object. It being understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.

The declaration was first stated in a letter from Arthur James Balfour, the British foreign secretary, to Baron Rothschild, a leader of British Jewry. After World War I the League of Nations endorsed the policy and made Palestine a British mandate.
