A rebellion in 1857 called the Sepoy mutiny of Bengal was the region's major armed struggle against the British. Divergence in the relationship between Hinduism and Islam created a major rift in British India that led to motivated religious violence in British India. The language controversy further escalated the tensions between Hindus and Muslims. The Hindu renaissance witnessed an awakening of intellectualism in traditional Hinduism and saw the emergence of more assertive influence in the social and political spheres in British India. A Muslim intellectual movement, founded by Sir Syed Ahmed Khan to counter the Hindu renaissance, envisioned, as well as advocated for the two-nation theory, and led to the creation of the All-India Muslim League in 1906. In contrast to the Indian National Congress's anti-British efforts, the Muslim League was a pro-British movement whose political program inherited the British values that would shape Pakistan's future civil society.

The largely non-violent independence struggle led by the Indian Congress engaged millions of protesters in mass campaigns of civil disobedience in the 1920s and 1930s against the British Empire.
