The provided records detail various historical milestones in Poland.

On July 22, the Polish Committee of National Liberation (PKWN) issued its manifesto in 1944, which served as the founding act of the Polish People’s Republic. This date was later used in 1983 to mark the lifting of martial law and the issuance of a broad amnesty after 19 months of the state of emergency.

August 20 is noted for several other events, including the 1920 retaking of Przasnysz from Bolshevik troops during the Battle of Warsaw and the 1944 capture of the PAST-a building by the ‘Kiliński’ battalion during the Warsaw Uprising. The date also marks the 1968 Warsaw Pact intervention in Czechoslovakia and the 1980 strikes that preceded the formation of the Solidarity movement.
