Facts and Events
Wiglaf (died 839) was King of Mercia from 827 to 829 and again from 830 until his death. His ancestry is uncertain: the 820s were a period of dynastic conflict within Mercia and the genealogy of several of the kings of this time is unknown. Wigstan, his grandson, was later recorded as a descendant of Penda of Mercia, so it is possible that Wiglaf was descended from Penda, one of the most powerful seventh-century kings of Mercia.
Wiglaf succeeded Ludeca, who was killed campaigning against East Anglia. His first reign coincided with the continued rise of the rival Anglo-Saxon kingdom of Wessex under Egbert. Egbert drove Wiglaf from the throne in 829, and ruled Mercia directly for a year. Wiglaf recovered the kingdom in 830, probably by force although it may be that Wiglaf remained subject to Egbert's overlordship. Mercia never regained the south-eastern kingdoms, but Berkshire and perhaps Essex came back into Mercian control. The causes of the fluctuating fortunes of Mercia and Wessex are a matter of speculation, but it may be that Carolingian support influenced both Egbert's ascendancy and the subsequent Mercian recovery. Although Wiglaf appears to have restored Mercia's independence, the recovery was short-lived, and later in the century Mercia was divided between Wessex and the Vikings.
