The Sangh Parivar refers, as an umbrella term, to the collection of Hindutva organisations spawned by the Rashtriya Swayamsevak Sangh (RSS), which remain affiliated to it. These include the political party Bharatiya Janata Party, religious organisation Vishva Hindu Parishad, students union Akhil Bharatiya Vidyarthi Parishad (ABVP), religious militant organisation Bajrang Dal that forms the youth wing of the Vishva Hindu Parishad (VHP), and the worker's union Bharatiya Kisan Sangh. It is also often taken to include allied organisations such as the Shiv Sena, which share the ideology of the RSS.
