Short answers, pulled from the story.
The All-India Muslim League was founded in December 1906 in Dacca, now Dhaka, during the twentieth session of the All-India Muhammadan Educational Conference, two months after a Muslim deputation met the Viceroy at Simla.
Khwaja Salimullah, the Nawab of Dacca, proposed the party and its name at the Dhaka session in December 1906, and the conference passed his motion unanimously. Sultan Muhammad Shah, the Aga Khan III, became its first honorary president, and Mohammad Ali Jauhar drafted its 1907 constitution, known as the Green Book.
The All-India Muslim League spearheaded the movement for Pakistan's creation, based on the two-nation theory associated with Syed Ahmad Khan. Under Muhammad Ali Jinnah, who joined in 1913 and led mass mobilization from 1937, it grew to over two million members and won 425 of 476 reserved Muslim seats in the 1946 provincial elections on a platform of creating Pakistan.
The All-India Muslim League wanted guaranteed political representation for Muslims apart from Hindu-majority electorates in British India's councils. It won partial separate electorates through the Indian Councils Act after protests and lobbying in London, and secured two further reserved Imperial Council seats through an Aga Khan-brokered compromise in 1909.
The All-India Muslim League was formally disbanded after the 1947 partition. It was succeeded by the Muslim League in Pakistan, later banned in 1958 and revived as the Pakistan Muslim League in 1962, and by the Indian Union Muslim League in India, which remains active in Kerala; in East Pakistan it was eventually succeeded by what is now the Awami League.
The All-India Muslim League was accused of using intimidation and coercion against Muslims who opposed partition, including attacks on scholar Hussain Ahmad Madani's rallies. In Sind, it was accused of subsidizing mobs that attacked Hindus and Sikhs in areas including Multan, Rawalpindi, and Jhelum, and its leaders issued no condemnation of that violence.
