Ladislaus III (1201-1205) was king of Hungary from 1204 to 1205. He was the son of Emeric of Hungary and Constance of Aragon, daughter of Alfonso II of Aragon. Ladislaus was crowned in 1204 while his father was still alive. Constance escaped to Vienna with Ladislaus when Ladislaus' uncle Andrew II became king. Ladislaus died there but was buried in Székesfehérvár in Hungary. Constance never returned to Hungary; instead she married Frederick II, Holy Roman Emperor. Andrew II was crowned king in 1205.
