During the 1936–1939 Arab revolt in Palestine, Ben-Gurion instigated a policy of restraint ("Havlagah") in which the Haganah and other Jewish groups did not retaliate for Arab attacks against Jewish civilians, concentrating only on self-defense. In 1937, the Peel Commission recommended partitioning Palestine into Jewish and Arab areas and Ben-Gurion supported this policy. This led to conflict with Ze'ev Jabotinsky who opposed partition and as a result Jabotinsky's supporters split with the Haganah and abandoned Havlagah.
