In a letter that British Foreign Secretary Balfour sent to Lord Rothschild, Britain offers to facilitate the growth of a national home for the Jewish people in Palestine with caveats that it will not prejudice civil and religious rights of the non-Jewish population there, or the political rights of Jews residing elsewhere. Chaim Weizmann is key to securing the letter. In 1922, the Declaration receives international legitimacy when its wording is incorporated into the League of Nations Mandate. Zionists fiercely defend the Mandate’s contents, while the Arab community in Palestine opposes it. (source)
