==Mikołajczyk's resignation, Provisional Government==

In October, Churchill and [[Anthony Eden]] went to Moscow, as did Mikołajczyk, Grabski and Romer. They negotiated again with Bierut, Osóbka-Morawski and Rola-Żymierski. Mikołajczyk resisted the British and Soviet pressure to accept the communist territorial and other demands. In November in London, the Polish government rejected the Curzon Line border again. President Roosevelt disappointed the Poles by designating the Polish, British and Soviet governments as the proper forum for border discussions, but Prime Minister Mikołajczyk, unable to convince his colleagues of the need for further compromises, resigned on 24 November 1944. The Polish government, now led by [[Tomasz Arciszewski]], was no longer seriously considered by the Allies.<ref name="Brzoza 364–374"/>

On 31 December 1944, the State National Council converted the PKWN to the [[Provisional Government of the Republic of Poland]], with Osóbka-Morawski as the prime minister. The Soviet Union recognized the new institution and the Western Allies did not object.<ref name="Brzoza 364–374"/> The KRN and the Provisional Government gradually strengthened their position, as the Soviet [[NKVD]] facilitated the process by performing large scale arrests of opponents of communist rule.<ref name="Brzoza 387–396"/>

The Provisional Government signed a 20-year friendship, alliance and cooperation treaty with the Soviet Union on 21 April 1945.<ref name="Czubiński historia Polski 229-233"/>
