The Polish People's Army (Ludowe Wojsko Polskie pronounced [luˈdɔvɛ ˈvɔi̯skɔ ˈpɔlskʲɛ], LWP) 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 (from 1952, the Polish People's Republic), 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 official name of those formations were: Armia Polska w ZSRR (Polish Army in the USSR) from 1943–1944, Wojsko Polskie (Polish Troops) and Siły Zbrojne Rzeczpospolitej Polskiej (Armed Forces of the Republic of Poland) from 1944–1952 and from 1952 Siły Zbrojne Polskiej Rzeczypospolitej Ludowej (Armed Forces of the Polish People's Republic).
After the war the Polish Army was reorganized into six (later seven) military districts. These were the Warsaw Military District, headquartered (HQ) in Warsaw, the Lublin Military District, HQ in Lublin, the Kraków Military District, HQ in Kraków, the Łódź Military District, HQ in Łódź, the Poznań Military District, HQ in Poznań, the Pomeranian Military District, HQ in Toruń, and the Silesian Military District, HQ in Katowice.
In the late 1940s and early 1950s, the Polish Army was under the command of Marshal of the Soviet Union, Marshal of Poland and Minister of Defense of Poland Konstantin Rokossovsky. It was increasingly integrated into Soviet military structures. This process was mitigated in the aftermath of the Polish October of 1956, when Władysław Gomułka formalized aspects of Poland's military relationship with the Soviet Union.
