Why was there tension within India's independence movement?

Gandhi led a non-violent revolution.

Explanation:

His methods were revolutionary. He was the first to lead his people to the revolution by non-violent methods. Civil disobedience was the main method of India's revolutionary path. However, this revolutionary path had many obstacles and even casualties. Thus, on one occasion, during a peaceful march of the Indian people in Amritsar, British General Dyer ordered the opening of fire on the people. About 4,000 people were killed and several thousand wounded. Gandhi also practiced a hunger strike on his revolutionary path, thus seriously endangering his health several times.
