Matthew III Csák
In present-day Slovakia, most of the castles were owned by two powerful aristocrats (Amade Aba and Matthew III Csák) or their followers. Following the extinction of the Árpád dynasty (1301), both of them pretended to follow one of the claimants for the throne, but, in practice, they governed their territories independently. Amade Aba governed the eastern parts of present-day Slovakia from his seat in Gönc. He was killed by Charles Robert of Anjou's assassins at the south gate in Košice in 1311.
