The First Battle of Langensalza was fought on 9 June 1075 between forces of King Henry IV of Germany and several rebellious Saxon noblemen on the River Unstrut near Langensalza in Thuringia. The battle was a complete success for Henry, resulting in the subjugation of the Saxons shortly before the Investiture Controversy commenced. In Germany the battle is known as the Schlacht bei Homburg an der Unstrut, after a nearby Kaiserpfalz and monastery.
