Politically the village belonged then to the Duchy of Oświęcim, formed in 1315 in the process of feudal fragmentation of Poland and was ruled by a local branch of Piast dynasty.

In 1457 Jan IV of Oświęcim agreed to sell the duchy to the Polish Crown, and in the accompanying document issued on 21 February the village was mentioned as Charmaszy.

Following the joint German-Soviet invasion of Poland, which started World War II in September 1939, the village was occupied and annexed by Nazi Germany.

In connection with the construction of the Auschwitz II-Birkenau death camp in nearby Brzezinka, in 1941, the occupiers expelled the entire Polish population of the village, which was initially deported to the nearby Pszczyna County, and afterwards either enslaved as forced labour or deported to the General Government in the more eastern part of German-occupied Poland.

[5] Afterwards, the Germans established and operated two subcamps of the Auschwitz concentration camp, in which men and women were imprisoned as slave labour.
