The 'two-nation theory', a key political concept in the history of the Indian subcontinent, was principally championed by the Muslim League. This theory posited that Muslims and Hindus constituted two separate nations, each possessing unique customs, religious beliefs, and traditions, and thus, Muslims were entitled to their own distinct nation.
