The success of "Maarmik" prompted Thackeray to form the Shiv Sena on 19 June 1966. The name "Shiv Sena" (Shivaji's Army) was after the 17th century Maratha king. Initially, Thackeray said it was not a political party but an army of Shivaji Maharaj, inclined to fight for the Marathi "manoos" (person). It demanded that native speakers of the state's local language Marathi (the "sons of the soil" movement) be given preferential treatment in private and public sector jobs. The early objective of the Shiv Sena was to ensure their job security competing against South Indians and Gujaratis. In its 1966 party manifesto, Thackeray primarily blamed south Indians. In "Marmik", Thackeray published a list of corporate officials from a local directory, many being south Indians, citing it as proof that Maharashtrians were being discriminated against.
