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.
