Quaid-e-Azam Muhammad Ali Jinnah began to participate in the meetings of the All-India Muslim League in various parts of India during the early months of 1913. He also began to share his views regarding policy and politics. He guided the objectives of the All-India Muslim League towards the national objectives. However, the membership of the All-India Muslim League for Jinnah was to come a little later, specifically on 10 October 1913 in London, where he signed the pledge for membership.
