In February 1945, at the conference at Yalta, Stalin demanded a Soviet sphere of political influence in Central Europe. Stalin eventually was convinced by Churchill and Roosevelt not to dismember Germany. Stalin stated that the Soviet Union would keep the territory of eastern Poland they had already taken via invasion in 1939, and wanted a pro-Soviet Polish government in power in what would remain of Poland. After resistance by Churchill and Roosevelt, Stalin promised a re-organization of the current pro-Soviet government on a broader democratic basis in Poland. He stated that the new government's primary task would be to prepare elections.
