The first written mention of Čáslavice is in a deed of the Porta coeli Convent from 1240. It was most likely founded at the turn of the 12th and 13th centuries at the latest. The village was first part of the Rokštejn estate. At the beginning of the 15th century, the village was bought by the Waldstein family and became part of the Sádek estate. The Waldsteins owned Čáslavice until 1676, when they sold it to the Waldorf family.

In 1708, most of Čáslavice was destroyed by a large fire. The village recovered and in 1864, it was promoted to a market town. However, it later lost the title.
