The Provisional Government of the Republic of Poland (Rząd Tymczasowy Rzeczypospolitej Polskiej, RTRP) was created by the State National Council (Krajowa Rada Narodowa) on the night of 31 December 1944. The Provisional Government of the Republic of Poland was created to take the place of the previous governmental body, the Polish Committee of National Liberation (Polski Komitet Wyzwolenia Narodowego or PKWN). Because of its location in Lublin, the PKWN was also known as the "Lublin Committee". The establishment of the RTRP was an important step in strengthening the control of the Polish Workers' Party and the Soviet Union in Poland. On 1 January 1945, the Polish Committee of National Liberation became the Provisional Government of Republic of Poland. In London, the Polish government-in-exile protested. They issued a declaration that the Soviet Union had "taken over the sovereign political rights of the Polish nation." The governments of Winston Churchill and Franklin D. Roosevelt also issued formal protest, but they took no further action. The Provisional Government of the Republic of Poland did not recognize the Polish government-in-exile and proclaimed itself to be the legitimate government of Poland. Initially, the RTRP was only officially recognized by the Soviet Union. But before the Yalta Conference, Joseph Stalin conveyed his intention to the Western Allies that Poland was under the control of the Soviet Union and that he intended for it to stay that way. The RTRP was given control of the Polish territories seized by the Red Army as it advanced westward. The RTRP was chaired by the previous Prime Minister of PKWN, Edward Osóbka-Morawski. The Deputy Prime Ministers of the RTRP were Władysław Gomułka of the Polish Workers' Party (PPR, for Polska Partia Robotnicza) and Stanisław Janusz from People's Party. The Minister of defense was Michał Rola-Żymierski. The Minister of Security was Stanisław Radkiewicz. The Polish Workers' Party declared that the RTRP was to be a coalition, but in practice all key posts were controlled by PPR.
