[1] The Provisional Governing Commission had been formed on 12 October 1920, following Żeligowski's Mutiny, in which forces from Poland, under the command of general Lucjan Żeligowski, had ceased Vilnius Region from Lithuania, and established the Republic of Central Lithuania, as the puppet state of Poland.
The formation of the executive government had been announced by Żeligowski, the commander-in-chief of Army of Central Lithuania, who de facto acted as the leader of the state.
It included Witold Abramowicz, Leon Bobicki, Mieczysław Engiel, Jerzy Iwanowski, Vatslav Ivanóvskiy, Teofil Szopa, and Aleksander Zasztowt.
[4] The Provisional Governing Commission formally ceased to exist on 6 April 1922, when the Legislative Sejm of Poland voted for the resolution to incorporate Central Lithuania into Polish territory.
Their deputy was the vice-chairperson, who deputized the chairperson in their responsibilities connected to running the Provisional Governing Commission.
