The Polish resistance refers to various underground movements that opposed the occupation of Poland during World War II, primarily by Nazi Germany and the Soviet Union. These groups engaged in sabotage, intelligence gathering, and armed conflict to undermine the occupiers and support the Allied forces. The most notable organization was the Home Army (Armia Krajowa), which coordinated efforts to resist both German and Soviet control. The resistance also included cultural and educational initiatives to preserve Polish identity and heritage. Members of the resistance faced severe reprisals, including imprisonment and execution, but their efforts played a crucial role in maintaining Polish sovereignty and morale during the war.
