Shiv Sena (
IAST: Siva Sena) (translation;
Army of Shivaji) also known by name
Sena, is an Indian
far-right regional political party. Its ideology is based on
Marathi nationalism and Hindu nationalism (
Hindutva), 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. It is currently headed by Thackeray's son,
Uddhav Thackeray. Members of Shiv Sena are referred to as
Shivsainiks.
