The Polish People's Army constituted the second formation of the Polish Armed Forces in the East in 1943–1945, and in 1945–1989 the armed forces of the Polish communist state, ruled by the Polish Workers' Party and then the Polish United Workers' Party. The communist-led Polish armed forces, allowed and facilitated by Joseph Stalin, were the result of efforts made in the early 1940s in the Soviet Union by Wanda Wasilewska and Zygmunt Berling.

The Constitution of the Polish People's Republic was a supreme law passed in communist-ruled Poland on 22 July 1952. It superseded the post-World War II provisional Small Constitution of 1947, which in turn replaced the pre-war April Constitution of 1935.
