On December 30 in 1906, the All India Muslim League, best known for securing India's partition into two nations, was founded. At the time of its founding, in Dhaka, the League was mostly a collective of elite Muslim men, and remained so for almost three decades. Muhammad Ali Jinnah, eventually its tallest leader, was then in the Congress. It was only in the late 1930s that it turned into a more mass organisation, and under Jinnah, spearheaded the Partition agitation. After Partition, the Muslim League was disbanded in India. In Pakistan and later in Bangladesh too, the League broke into factions and did not survive long. Here are 3 things you should know about the Muslim League, and its role in India's politics.
