Włoszczowa was first mentioned in 1154, when Prince Henryk Sandomierski handed the village known then as Vloszcova to the Sovereign Military Order of Malta monks. It received its town charter in 1539, when King Zygmunt Stary handed the document to the starosta of Chęciny, Hieronim Szafraniec. The town remained the property of the Szafraniec family until the late 18th century.
