Shiv Sena (Marathi) is a Marathi chauvinistic and Hindu nationalist political organisation in India founded on 19 June 1966 by political cartoonist Bal Thackeray. The party originally emerged from a movement in Mumbai demanding preferential treatment for Maharashtrians over migrants to the city. The party has a powerful hold over the Bollywood film industry.It is currently headed by Thackeray's son, Uddhav Thackeray. Members of Shiv Sena are referred to as Shiv Sainiks. The group has been seen by some as a terror group,and has been linked directly with the 1970 communal violence in Bhiwandi, 1984 Bhiwandi riots, and violence in the 1992-1993 Bombay riots.
