[6][12] The party was founded on 19 March 2007 by Silesian activists Dariusz Jerczyński, Grzegorz Kot and Marcela Tampa.

[1] The Silesian Separatist Movement was registered as a political association on 19 March 2007, with Grzegorz Kot, Dariusz Jerczyński and Marcela Tampa listed as the leadership of the party.

The Movement was closely associated with Związek Ludności Narodowości Śląskiej (People of the Silesian Nation) and was to be a branch of the organisation.

In autumn 2007, Dariusz Jerczyński made contact with the leaders of the Federation for the Development of Silesia - Grzegorz Kot and Marceli Potempa, to create a new Silesian National Movement on the basis of their former organisation.

Because the local district court objected to this name, the organisation was finally registered under the name Silesian Separatist Movement, and Jerczyński became its general secretary.

In 2007, Grzegorz Kot participated in the Polish parliamentary election, where he ran for a seat in the Senate of Poland on behalf of the People of the Silesian Nation; he obtained 385 votes.

Kot also participated in the 2010 Polish local elections, running for the Katowice city council as a candidate of the Silesian Autonomy Movement; he won 51 votes.

Naturski referred to the Silesian Autonomy Movement as separatist and denounced its proposals to federalize Poland as a scheme to fracture the Polish state.

[9] The movement supported the 2015 Polish referendum and stated its belief that Silesia should adopt a system of direct democracy similar to that of Switzerland.

The leader of the party, Dariusz Jerzyński, published a controversial book "History of the Silesian people" which argued that Silesia is culturally separate from Poland and had undergone different socioeconomic, political and historical developments.
