With the German invasion of Poland and the outbreak of the Second World War in September 1939, Turek was occupied by the Wehrmacht and annexed by Nazi Germany. It was administered as part of the county or district (kreis) of Turek within newly formed province of Reichsgau Wartheland. The Polish population was subjected to expulsions, confiscation of property, deportations to Nazi concentration camps and murder (see Nazi crimes against the Polish nation). In autumn of 1939, the Einsatzgruppe VI carried out a number of executions of Poles at the local market.[6] Teachers from Turek were among Polish teachers murdered in the Mauthausen concentration camp.[7] The first expulsion of 160 Poles was carried out in December 1939, and the expellees' shops, workshops and houses were then handed over to German colonists as part of the Lebensraum policy.[8] A transit camp for Poles expelled from the region was operated in the town.[9] During the German occupation, the nearly 3,000 Jews in Turek were brutalized, forced into an overcrowded ghetto in 1940, starved, and robbed of all their possessions. In 1941, some men were sent to forced labour camps near Poznań, but the majority of Turek's Jews were sent to a rural ghetto in Kowale Pańskie. In July 1942, most of them were sent to the Chełmno extermination camp where they were gassed immediately. Only around 30 Turek Jews survived the war.
