Explain briefly how did Mahatma Gandhi try to promote Hindu-Muslim unity from the Rowlatt Satyagraha to the Third Round Table conference.

Mahatma Gandhi tried to promote Hindu-Muslim unity from the Rowlatt Satyagraha to the Third Round Table conference in the following ways:

1. Rowlatt Satyagraha — An important feature of the Rowlatt Satyagraha was Hindu-Muslim unity. This was the call given by Mahatma Gandhi, who always saw a unified India belonging to the people of all religions. He wanted that Hindus and Muslims should support each other in any just cause.
2. Khilafat movement — Gandhiji saw in the Khilafat Movement an opportunity for uniting Hindus and Muslims. He said that the Congress plea for Hindu-Muslim unity "would be an empty phrase if the Hindus hold aloof from the Muslims when their vital interests are at stake".
3. Non-Cooperation Movement — It fostered Hindu-Muslim unity which could be seen in the merger of the Khilafat issue with this Movement. It provided an opportunity to the Congress to bring the urban Muslims into the National Movement by convincing them that the nation was equally concerned with the problems affecting them.
