Hindu Munnani
Hindu Munnani is a right-wing Hindu nationalist organisation based in the Indian state of Tamil Nadu. Hindu Munnani was set up by Rashtriya Swayamsevak Sangh (RSS) The organisation was founded in 1980 by Ramagopalan, a member of RSS and since its formation served as the platform for RSS and its subsidiaries known as the Sangh Parivar. The organisation promoted a Hindu identity and used it as a political mobilisation strategy. The AIADMK government in the 1990s was in alliance with the Hindutva aligned Bharatiya Janata Party which enabled Hindu Munnani in organizing Vinayaka Chathurthi processions in major cities of Tamil Nadu. The state government's support of Rama Gopalan's activity made him a follower of Jayalalitha. Due to the proximity, a faction of the group broke away and found another group named Hindu Makkal Katchi in 1993. The militants of the Hindu Munnani used vituperative and abusive language against the Muslims. The provocative speeches against Islam and Prophet Muhammad polarized the social atmosphere of the region. Their anti-Muslim speeches and activities led to formation of radical muslim terrorist organisation  Al Umma. The activities of R.S.S., Hindu Munnani and Hindu Makkal Katchi continued uninterrupted under Jayalalitha. The BJP alliance with AIADMK led to further spread of RSS ideology in Tamil Nadu. Activities
The Hindu Munnani first gained public awareness in 1982 when it began to incite the Hindu population of Ramanathapuram district against the Meenakshipuram conversions by Ishaatul Islam Sabha of South India. However, the most remarkable achievement of the Hindu Munnani was the organisation of Vinayaka Chathurthi processions in Tamil Nadu. On 16 May 2006, the Hindu Munnani organised the Silver Jubilee celebrations of the installation of the shivalinga in the Jalakanteswarar temple in Vellore. The Vinayaga Chathurthi celebrations organised by the Hindu Munnani were often accompanied by sporadic incidents of communal violence. In 1993, there were bomb attacks made on the R.S.S. state headquarters at Chintadripet, Chennai. Islamic organisations were found guilty for the blasts and a crackdown was launched on extremist Islamic organisations. 1997 Coimbatore riots occurred between 29 November 1997 and 1 December 1997 in Coimbatore triggered by a murder of a police constable allegedly by some Muslim youth over a dispute of detention of Al-Ummah functionaries by the police. The policemen revolted in response to the murder of the constable and in concert with the members of Hindu Munnani and Hindu Makkal Katchi, attacked Muslims and Muslim-owned properties. Clashes erupted between both the communities and the police reportedly opened fire targeting the Muslims killing ten. Many Muslim youth were beaten to death or burnt alive. Muslim-owned businesses in different parts of the city were looted and burnt down. At the end of the riots, 18 Muslims and 2 Hindus lost their lives. During the visit of Bharatiya Janata Party (BJP) leader L. K. Advani and Indian Prime Minister Atal Bihari Vajpayee to Coimbatore in 1998, a series of thirteen blasts rocked the city, killing over fifty-eight people. The Coimbatore bombings were considered a response to the 1997 Coimbatore riots. In 2007, there were clashes between the Hindu Munnani and the Dravida Munnetra Kazhagam (DMK) over the remarks made by BJP leader Vedanti on DMK President and Chief Minister Karunanidhi. DMK cadres attacked the Hindu Munnani state headquarters in Chennai on motorbikes. In September 2017, Six members of Hindu Munnani were arrested in connection with the murder of CPI member K.
