The Raj was slow to allow self-rule in the colonial subcontinent. It established the Bengal Legislative Council in 1862, and the council's native Bengali representation increased during the early 20th century. The Bengal Provincial Muslim League was formed in 1913 to advocate civil rights for Bengali Muslims within a constitutional framework. During the 1920s, the league was divided into factions supporting the Khilafat movement and favouring co-operation with the British to achieve self-rule. Segments of the Bengali elite supported Mustafa Kemal Atatürk's secularist forces. In 1929, the All Bengal Tenants Association was formed in the Bengal Legislative Council to counter the influence of the Hindu landed gentry, and the Indian Independence and Pakistan Movements strengthened during the early 20th century. After the Morley-Minto Reforms and the diarchy era in the legislatures of British India, the British government promised limited provincial autonomy in 1935. The Bengal Legislative Assembly, British India's largest legislature, was established in 1937.
