Balfour Declaration and the Mandate for Palestine Lobbying by Russian Jewish immigrant Chaim Weizmann, together with fear that American Jews would encourage the US to support Germany in the war against Russia, culminated in the British government's Balfour Declaration of 1917. It endorsed the creation of a Jewish homeland in Palestine, as follows: In 1922, the League of Nations adopted the declaration, and granted to Britain the Palestine Mandate: Weizmann's role in obtaining the Balfour Declaration led to his election as the Zionist movement's leader. He remained in that role until 1948, and then was elected as the first President of Israel after the nation gained independence. A number of high-level representatives of the international Jewish women's community participated in the First World Congress of Jewish Women, which was held in Vienna, Austria, in May 1923. One of the main resolutions was: "It appears ... to be the duty of all Jews to co-operate in the social-economic reconstruction of Palestine and to assist in the settlement of Jews in that country."

The Arabs opposed the partition plan and Britain later rejected this solution and instead implemented the White Paper of 1939. This planned to end Jewish immigration by 1944 and to allow no more than 75,000 additional Jewish migrants. At the end of the five-year period in 1944, only 51,000 of the 75,000 immigration certificates provided for had been utilized, and the British offered to allow immigration to continue beyond cutoff date of 1944, at a rate of 1500 per month, until the remaining quota was filled.
