Czemierniki was granted
town rights in 1509 by King
Sigismund I the Old thanks to efforts of heir
Mikołaj Firlej. In 1622, Bishop of Płock
Henryk Firlej erected a palace with adjent gardens, thanks to which, according to the 19th-century
Geographical Dictionary of the Kingdom of Poland, Czemierniki was "famous as one of the most beautiful towns in Poland". Following the joint German-Soviet
invasion of Poland, which started
World War II in September 1939, the town was
occupied by Germany. Around 1,000 Jews were put into the Czemierniki
ghetto, established by the Nazis in 1940. In 1942, Czemierniki Jews were sent to the
Parczew ghetto, and then to the
Treblinka concentration camp. Few Jews survived. ==References==
