Explanation:

by the Khilafat Conference

The growing indignation against the British rule led to the launching of the Khilafat and Non-Cooperation movement. Turkey had fought against Britain in the First World War. Turkey, which was one of the defeated countries, suffered injustices at the hands of Britain. In 1919, a movement was organised under the leadership of Mohammad Ali and Shaukat Ali (popularly known as Ali brothers), Abul Kalam Azad, Hasrat Mohani and others to force the Britain government to undo these injustices. The Khilafat committee which was set up to conduct this movement was joined by Gandhi. The sultan of Turkey was also considered the Caliph or Khalifa, the religious head of the Muslims. Therefore the movement over the question of the injustice done to Turkey was called the khilafat movement. It gave a call for non-cooperation. The movement on the Khilafat question soon merged with the movement against the repression in Punjab and for swaraj.
