In 1936, following a wave of violence initiated by the Arabs against the Jewish Yishuv, the British sent a royal commission to Palestine, headed by Lord Peel (the Peel Commission). This recommended partitioning Palestine into two states: a small Jewish state in the Galilee, the northern valleys and the coastal plain; an Arab state in the rest of the country, and a British "corridor" that would include Jaffa, Jerusalem and everything in between. The Arabs rejected the royal commission proposal; some Jews believed that it should be approved, and this caused bitter argument at the Twentieth Zionist Congress. In any case, the British went back on their proposal and adopted an anti-Zionist policy (the White Paper of 1939).
