The liberation of Warsaw refers to several different historical events, but the most notable is likely that of World War II. In 1944, the Polish resistance, primarily represented by the Home Army (Armia Krajowa), launched an armed uprising against the German occupation of Warsaw.
This uprising, known as the Warsaw Uprising, began on August 1, 1944. The fighting was intense and fierce, but unfortunately, the Polish forces were quickly overwhelmed by the German firepower. Despite initial support from the Allies, who had encouraged the uprising, no significant aid was provided to the Polish forces.
After 63 days of fighting, the Polish forces surrendered on October 2, 1944. This event was followed by a brutal German crackdown, with thousands of civilians killed and the city of Warsaw largely destroyed. The liberation of Warsaw only occurred in January 1945 when the Soviet Red Army finally drove out the German forces from the city.
However, the liberation by the Soviets did not mean true freedom for Poland, as it was followed by the establishment of a communist regime supported by Moscow, which lasted until 1989.
