Hindu–Muslim unity is a religiopolitical concept in the Indian subcontinent which stresses members of the two largest faith groups there, Hindus and Muslims, working together for the common good. The concept was championed by various persons, such as leaders in the Indian independence movement, namely Mahatma Gandhi and Khan Abdul Ghaffar Khan, as well as by political parties and movements, such as the Indian National Congress, Khudai Khidmatgar and All India Azad Muslim Conference. Those who opposed the partition of colonial India often adhered to the doctrine of composite nationalism.
