In 1937, following the Great Arab Revolt, the partition plan proposed by the Peel Commission was rejected by both the Palestinian Arab leadership and the Zionist Congress. As a result, believing that their position in the Middle East in the event of a war depended on the support of the Arab states, Britain abandoned the idea of a Jewish state in 1939 in favour of a unitary state with a Jewish minority. The White Paper of 1939 capped Jewish immigration for five years, with further immigration dependent on the agreement of the Arabs. In the event, limited Jewish immigration was permitted until the end of the mandate.
