What happened 933 AD

Henry (Henry the Fowler) reached a truce with the raiding Magyars, and in 933 he won a first victory against them in the Battle of Riade. The Battle of Riade or Battle of Merseburg was fought between the troops of East Francia under King Henry I and the Magyars at an unidentified location in northern Thuringia along the river Unstrut on 15 March 933. The battle was precipitated by the decision of the Synod of Erfurt to stop paying an annual tribute to the Magyars in 932.

According to Elogius Kiburger, the author of the Strättliger Chronicle, in 933 the King of Burgundy, Rudolph II, built the Castle.
