Explanation:

Between 1916 and 1918, when the World War-I was gradually approaching an end, prominent Indians like Muhammad Ali Jinnah, Bal Gangadhar Tilak, Sir S. Subramania Iyer, Annie Besant decided to organise a national alliance of leagues across India. It was specifically to demand Home Rule, or self-government within the British Empire for all of India. It was run separately from both parties. Some members of both INC and AIML joined the Home Rule movement. In 1920, the All India Home Rule League elected Mahatma Gandhi as its President. In a year, the body would merge into the Indian National Congress to form a united Indian political front.
