[8] When on 10 January 1920 the regulations of the Treaty of Versailles became effective, the village together with the former Kreis Tuchel became part of the Second Polish Republic, which regained independence after World War I.

On September 30, 1939, members of the German minority from Selbstschutz committed a massacre of 48 people in the village, including two Poles and 46 Jews.

Among the Germans following names were identified: Helmut Bratsch, Hans Briske, Walter Klos, Kurt Merten-Feddler and Willy Müller.

On November 26, 1939, Nowa Tuchola was annexed into the newly formed province of Reichsgau Danzig-West Prussia – in the new administrative district of Regierungsbezirk Bromberg.

After the end of the war the village was restored to Poland, although with a Soviet-installed communist regime, which stayed in power until the Fall of Communism in the 1980s.
