In April 1915, Russia supported the establishment of the Armenian provisional government under Russian-Armenian Governor Aram Manukian, leader of the resistance in the Defense of Van. The Armenian national liberation movement hoped that Armenia could be liberated from the Ottoman regime in exchange for helping the Russian army. However, the Tsarist regime had a secret wartime agreement with the other members of the Triple Entente about the eventual fate of several Anatolian territories, named the Sykes–Picot Agreement. These plans were made public by the Armenian revolutionaries in 1917 to gain the support of the Armenian public.
