Wenceslaus III
Wenceslaus III was king of Bohemia and Poland. He briefly was also the king of Hungary and Croatia. His Czech name was Vaclav. His Hungarian name was Vencel, although he often used the name Ladislaus in Hungary.
History
Wenceslaus III was the only surviving son of Wenceslaus II.
In 1298 he was betrothed to Elizabeth, the only daughter and heir of Andrew III, king of Hungary.
Reign
Hungary
After Andrew III died in 1301, the kingdom of Hungary and Croatia began to disintegrate. A set of oligarchs were de facto rulers across the realm: Matthew Csak in modern Slovakia, Amadeus Aba in the northeast, Ivan Koszegi in Transdanubia, and Ladislaus Kan in Transylvania. Paul I, the ban of Croatia, arranged for Charles I to travel to Split. He was crowned in Esztergom on May 13.
The local nobility instead elected Wenceslaus III, and crowned him in Szekesfehervar. In Hungary he was referred to as either Wenceslaus I or Ladislaus.
Wenceslaus II invaded and occupied most of Hungary to keep the kingdom for his son.
Bohemia
Wenceslaus II died on June 21, 1305. Now Wenceslaus III held three kingdoms, two of which were in rebellion. He renounced his claims to the kingdom of Hungary and Croatia in favor of Otto III, so that he could focus on Poland without allowing Charles I too much power. Wladyslaw I however quickly advanced and occupied Krakow.
Wenceslaus III was assassinated on August 4, 1306.
