In September 1939, Poland was invaded by Nazi Germany and the Soviet Union, starting World War II. The war's end in 1945 marked not the true liberation of the country, but the beginning of a period of Soviet domination that ended only in 1989. As a result, for forty-five years of Polish history, the alliance made by the Hitler with Stalin in 1939 and its tragic consequences for Poland were taboo across society. Polish filmmakers presenting the beginning of World War II were constrained by realities of the Communist state and its own historical narratives. These films reflect what happened to their country in 1939 and highlight the political changes that occurred within Poland under Communist rule, as well as the impact of shifts in the regime itself. The most significant period in this regard was 1945-67, when the outbreak of war was first presented following the end of Stalinism, emerging as a component of national memory both generally and for the Communist authorities.
