Sigurd the Crusader, Norwegian king (b. 1090)
Sigurd I Magnusson (1089 – 26 March 1130), also known as Sigurd the Crusader (Old Norse: Sigurðr Jórsalafari, Norwegian: Sigurd Jorsalfar), was King of Norway from 1103 to 1130. His rule, together with his half-brother Øystein (until Øystein died in 1123), has been regarded by historians as a golden age for the medieval Kingdom of Norway. He is otherwise famous for leading the Norwegian Crusade (1107–1110), earning the eponym "the Crusader", and was the first European king to personally participate in a crusade.
