Wenceslaus III was King of Hungary and Croatia between 1301 and 1305, and King of Bohemia and Poland from 1305. He was the son of Wenceslaus II, King of Bohemia, who was later also crowned king of Poland, and Judith of Habsburg.

Still a child, Wenceslaus was betrothed to Elizabeth, the sole daughter of Andrew III of Hungary. Wenceslaus was crowned king of Hungary on 27 August 1301. He signed his charters under the name Ladislaus in Hungary. His rule was the only nominal because a dozen powerful lords held sway over large territories in the kingdom. His father realized that Wenceslaus's position could not be strengthened and took him back from Hungary to Bohemia in August 1304. Wenceslaus succeeded his father in Bohemia and Poland on 21 June 1305. He abandoned his claim to Hungary in favour of Otto III of Bavaria on 9 October.

His coins depict the king on horseback on the side and crowned griffin or eagle on the other side. Here is an image of Wenceslaus's silver denarius. Image Source: Wikipedia.org
