Political Engagement

Piekałkiewicz entered organized politics in 1926 through the Polish People's Party 'Piast'. By 1931, he was active in the People's Party, eventually serving on its Main Council between 1938 and 1939. Following the German occupation of Poland, he remained active within the People's Party 'Roch'. In December 1940, he assumed the role of Deputy to the Polish Underground State's Government Delegate, succeeding Cyryl Ratajski as the primary Delegate in 1942.

Wartime Leadership and Death

As Government Delegate, Piekałkiewicz oversaw the establishment of the Council to Aid Jews, known as Żegota, and mandated the documentation of Nazi crimes against Poles and Jewish citizens. He communicated intelligence regarding the Holocaust to Western Allies and drafted plans for post-war Polish borders. His work in the underground press served to mobilize civilian resistance and warn collaborators of impending justice. On 19 February 1943, German authorities arrested Piekałkiewicz. Following a period of torture, he was murdered on 19 June 1943. He is buried at the Powązki Cemetery and was posthumously awarded the Order of the White Eagle in 1995.
