Hindutva is the predominant form of Hindu nationalism in India. The term Hindutva was first used by Chandranath Basu in 1892 and later the term was popularised by Vinayak Damodar Savarkar in 1923. It is championed by the Hindu nationalist volunteer organisation Rashtriya Swayamsevak Sangh (RSS), the Vishva Hindu Parishad (VHP), the Bharatiya Janata Party (BJP) and other organisations, collectively called the Sangh Parivar. The Hindutva movement has been described as a variant of "right-wing extremism" and as "almost fascist in the classical sense", adhering to a disputed concept of homogenised majority and cultural hegemony. Some dispute the fascist label, and suggest Hindutva is an extreme form of "conservatism" or "ethnic absolutism".
