Ladislaus III of Hungary

Ladislaus III (Hungarian: László; 1201-7 May 1205) was King of Hungary from 1204 to 1205. He was the son of King Emeric of Hungary and Constance of Aragon, daughter of Alfonso II of Aragon. Ladislaus was crowned on 26 August 1204 while his father was still alive. With that, the old king wanted to ensure his sons power and guarantee the succession to the throne. Emeric made his brother, Andrew promise that he will protect the child and help him in the governance until he is an adult. Andrew promised this, but just after Emeric's death, he grabbed all power to him and made the life of the little child and his mother, Constance hard.

Constance escaped to Vienna to Leopold VI with Ladislaus. Just after that, Ladislaus' uncle Andrew II became king of Hungary. Ladislaus died in Vienna 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.

Ladislaus III was a king of Hungary, who, because of his short life, hardly had any influence on the Hungarian history.
