During the Ottoman-Russian War of 1853-1856, a great Kurdish revolt broke out against the Ottomans with the support of local Christian communities. Yazdan Shir, the leader of this revolt, attempted to co-ordinate his military efforts with the Russian armies. But he failed to establish a direct communication line with Russian forces. According to Ahmad, the Ottoman forces succeeded, with direct British support, in suppressing this revolt.
