What was the period of Khilafat movement?
Khilafat movement was originally in support of Caliph who was the religious head of the Muslims. Gandhiji saw an opportunity for a Hindu-Muslim mass movement and hence joined his non-cooperation with the khilafat issue. It was started in the year 1919. The non-cooperation movement started to spread in different parts of the country.
In September 1921, the Ali brothers (Muhammad Ali and Shaukat Ali) were
arrested who had started the movement. Moreover, Gandhiji suspended the
Non-Cooperation Movement after the Chauri Chaura incident. He was
arrested in 1922.
