Piotrków Kujawski [ˈpʲɔtrkuf kuˈjafskʲi] is a town in Radziejów County, Kuyavian-Pomeranian Voivodeship, Poland,[1] with 4,463 inhabitants (2004).

[2] After the joint German–Soviet invasion of Poland, which started World War II, Piotrków Kujawski was occupied by Germany from 1939 to 1945.

[3] In 1939, the Germans carried out a massacre of 22 Poles, including 8 Catholic priests, in the town.

[4] Under the German occupation, the Jews, whose pre-war population numbered between 800 and 900, were placed in a ghetto, stripped of their possessions, and forced to do unpaid labor.

In April 1942, the remaining Jews were rounded up and sent in trucks to the Chełmno extermination camp where they were immediately murdered.
