During World War II the village was occupied by Germany. In September 1944, during the Warsaw Uprising, the Germans deported 2,000 Varsovians from the Dulag 121 camp in Pruszków, where they were initially imprisoned, to Kłomnice. Those Poles were mainly old people, ill people and women with children.
