Home Army
The Home Army (Polish: Armia Krajowa, pronounced [ˈarmja kraˈjɔva]; abbreviated AK) was the dominant resistance movement in German-occupied Poland during World War II. The Home Army was formed in February 1942 from the earlier Związek Walki Zbrojnej (Armed Resistance) established in the aftermath of the German and Soviet invasions in September 1939. Over the next two years, the Home Army absorbed most of the other Polish partisans and underground forces.
