Solution:The Muslims of India considered the Sultan of Turkey as the Khalifa (Caliph) of the Islamic empire. In the First World War, Turkey was fighting against allied countries. Before the war, the British Government had promised fair treatment to Turkey to win the support of Indian Muslims.Turkey was dismembered, and the Khalifa was stripped of his post. This act of the British angered Indian Muslims. As a result, they started a movement to defend the Ottoman Empire of Turkey and to retain the Khalifa in his post.
The Khilafat Movement started to protest against the partition of Turkey and acquired an aggressive approach with the joining of Gandhi in the movement.
