Figure 11. Postwar Territorial Adjustments, 1945

Soviet success in liberating Poland began an entirely new stage in Polish national existence. With the reluctant blessing of the Allies, the communist-dominated government was installed in 1945. During the next seven years, Poland became a socialist state modeled on the Soviet Union. Although Poland remained within this political structure through the 1980s, open social unrest occurred at intervals throughout the communist period. Protests in 1980 spawned the Solidarity (Solidarnosc) labor movement, which forced fundamental compromise in the socialist system.
