Although both the Turks and the British used Kurdish tribes to instigate cross-border conflicts, local shaykhs recruited Kurds to revolt against the regional powers. The first of these Kurdish call-to-arms occurred in British controlled Southern Kurdistan in May 1919. Shortly before being appointed governor of Sulaymaniyah, Shaykh Mahmud Barzanji ordered the arrest of all British political and military officials in the region. After seizing control of the region, Barzanji raised a military force from his Kurdish tribal followers in Iran and proclaimed himself "Ruler of all of Kurdistan".
