Hindutva ("Hinduness", a word coined by Vinayak Damodar Savarkar in his 1923 pamphlet entitled Hindutva: Who is a Hindu? ) is used to describe movements advocating Hindu nationalism.

The former ruling party in India, the Bharatiya Janata Party (BJP) is closely associated with a group of organizations that promote Hindutva. They collectively refer to themselves as the "Sangh Parivar" or family of associations, and include the Rashtriya Swayamsevak Sangh, Bajrang Dal and the Vishwa Hindu Parishad.

This ideology has existed since the early 20th century, forged by freedom fighter Vinayak Damodar Savarkar popularly known as Veer Savarkar (Veer means brave), but came to prominence in Indian politics in the late 1980s, when two events attracted a large number of mainstream Hindus to the movement. The first of these events was the Rajiv Gandhi government's use of its large Parliamentary Majority to overturn a Supreme Court verdict granting alimony to an old woman that had angered many Muslims (see the Shah Bano case). The second was the dispute over the 16th century Mughal Babri Mosque in Ayodhya — built by Babur after his first major victory in India. The Supreme Court of India refused to take up the case in the early 1990s, leading to a huge outcry. Tempers soon flared, and Hindutva supporters razed the mosque in late 1992. The razing of the mosque and subsequent conflict arguably lifted the BJP and Hindutva to international prominence.
