After the German Invasion of Poland it was annexed into the Third Reich, from 1939 to 1945 as part of Reichsgau Danzig-West Prussia. During the German occupation, Poles were subjected to mass arrests and executions as part of the "Intelligenzaktion Pommern". The Germans established a prison in the local courthouse, in which around 200 Poles were imprisoned and tortured in September and October 1939, before being murdered in large massacres in the nearby village of Grupa. Towards the end of World War II, Nowe was captured by the Red Army and after the end of the war, it was restored to Poland.
