AK (Armia Krajowa)

Armia Krajowa (AK), or the Home Army, was the primary Polish resistance organization during World War II (1939–1945). It operated secretly within Nazi-occupied Poland, engaging in sabotage, intelligence gathering, and assisting Allied efforts. The AK aimed to resist German control, restore Poland's independence, and support underground education and culture. It was highly organized, with thousands of members risking their lives to oppose the occupiers. Although its main military actions declined after 1944, the AK symbolized Polish patriotism and resilience during a challenging period of occupation and war.
