Polish Underground State's Day(Poland)
Commemorates the establishment of the Polish Underground State during WWII in 1939.
Polish Underground State’s Day on September 27 honors the secret government established under Nazi occupation in 1939. This clandestine administration coordinated military resistance, education, and civil services across occupied Poland. The day features ceremonies at Warsaw’s monuments, educational programs, and veteran reunions. Schools teach about the bravery of the Home Army (Armia Krajowa) and the legacy of civilian resistance. The observance preserves the memory of those who risked their lives to maintain national sovereignty under oppression.
