The theory and the very existence of Pakistan has caused Indian far-right extremist groups to allege that Indian Muslims "cannot be loyal citizens of India" or any other non-Muslim nation, and are "always capable and ready to perform traitorous acts". Constitutionally, India rejects the two-nation theory and regards Indian Muslims as equal citizens. The official Indian perspective maintains that the partition of India was a result of Britain's divide-and-rule policy that aimed at dividing Hindus and Muslims after they united together to fight the British in the Indian Rebellion of 1857.
