During the 12th and 13th centuries, Topoľčany was owned by the Csak family, its best-known member being Matthew III Csák. In the 15th century, the castle was conquered and held by the Hussites for 3 years, who returned it for a fee of 9000 ducats in 1434. In 1443 the countryside was pillaged by a rogue noble who had captured the castle, but was later evicted by the king and sent to Moravia. In the same year, and again in 1444, the town (and much of Carpathia) was struck by an earthquake.
