After Offa's death in 796, Mercian power over England was weakened. There was a period of three years when some West Saxons tried to break free of Mercian control. But Beorhtric and Cenfulf, the new king, signed a peace treaty. From that time on Wessex remained subordinate to Mercia. Three West Saxon coins have survived from Beorhtric's reign. In style they are very similar to coins struck by Offa. They were probably minted at Southampton after Offa's death.
