Ladislaus IV, King of Hungary, is assassinated at the castle of Körösszeg (modern-day Cheresig in Romania).

Ladislaus IV, also known as Ladislaus the Cuman, was King of Hungary and Croatia from 1272 to 1290. His mother, Elizabeth, was the daughter of a chieftain from the pagan Cumans who had settled in Hungary. At the age of seven, he married Elisabeth, a daughter of King Charles I of Sicily. Ladislaus was only 9 when a rebellious lord, Joachim Gutkeled, kidnapped and imprisoned him.

The King of Hungary was the ruling head of state of the Kingdom of Hungary from 1000 to 1918. The style of title "Apostolic King of Hungary" was endorsed by Pope Clement XIII in 1758 and used afterwards by all monarchs of Hungary.
