Lothair III, sometimes numbered Lothair II and also known as Lothair of Supplinburg (c. June 1075 – 4 December 1137), was Holy Roman Emperor from 1133 until his death. He was appointed Duke of Saxony in 1106 and elected King of Germany in 1125 before being crowned emperor in Rome. The son of the Saxon count Gebhard of Supplinburg, his reign was troubled by the constant intriguing of the Hohenstaufens, Duke Frederick II of Swabia and Duke Conrad of Franconia. He died while returning from a successful campaign against the Norman Kingdom of Sicily.
