There were only 230 Jews in Tuliszków at the onset of war, around 10% of the general population. In December 1939 the invading Germans ordered the creation of a "Judenrat" and forced all adult Jews to wear the Star of David; the community was stripped of money and valuables. Within weeks the ghetto was formed, and electricity was cut off from it in the dead of winter. Stronger Jews were pressed to forced labour. The ghetto was liquidated in October 1941 and all Jews – men, women and children – deported to transit ghetto in Kowale Pańskie. Some escaped from that ghetto and returned to Tuliszkow to hide. Others were sent to forced labor camps near Poznan or to Lodz. Most of those in the Kowale Pańskie ghetto were sent to Chełmno extermination camp. Only one Tuliszkow Jew is known to have survived the war.
