Uther has ruled Camelot and its Kingdom for at least 21 years. After discovering his wife Igraine was unable to bear a child to suceed the throne it appears he sent Gaius to the Isle of the Blessed to ask Nimueh for help. As a consequence of using magic Igraine had to die during the birth to preserve the balance of Life and Death (Excalibur)

Uther threw Nimueh from Court and killied all users of magic he could hunt down in The Great Purge. This ended with the capture of The Great Dragon who was imprisoned under Camelot Castle to serve as an example.
