History

In 1827, Komorowo had a population of 185, which by the 1880s grew to 385. In the interbellum, barracks of the Polish 18th Light Artillery Regiment were located in Komorowo. Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the village was occupied by Germany. In 1941–1943, the Germans operated the Stalag 333 prisoner-of-war camp in the pre-war barracks.
