In February 1917 the tsar was overthrown and Alexander Kerensky became Prime Minister of the Russian Empire. Jews were prominent in the new government and the British hoped that Jewish support would help keep Russia in the war. In June 1917 the British army, led by Edmund Allenby, invaded Palestine. The Jewish Legion participated in the invasion and Jabotinsky was awarded for bravery. Arab forces conquered Transjordan and later took over Damascus.
