Wulfhere of Mercia

Wulfhere or Wulfar (died 675) was King of Mercia from 658 until 675 AD. He was the first Christian king of all of Mercia, though it is not known when or how he converted from Anglo-Saxon paganism. His accession marked the end of Oswiu of Northumbria's overlordship of southern England, and Wulfhere extended his influence over much of that region. His campaigns against the West Saxons led to Mercian control of much of the Thames valley. He conquered the Isle of Wight and the Meon valley and gave them to King Æthelwealh of the South Saxons. He also had influence in Surrey, Essex, and Kent. He married Eormenhild, the daughter of King Eorcenberht of Kent.

Wulfhere's father, Penda, was killed in 655 at the Battle of Winwaed, fighting against Oswiu of Northumbria. Penda's son Peada became king under Oswiu's overlordship but was murdered six months later. Wulfhere came to the throne when Mercian nobles organized a revolt against Northumbrian rule in 658 and drove out Oswiu's governors.

By 670, when Oswiu died, Wulfhere was the most powerful king in southern England. He was effectively the overlord of England south of the Humber from the early 660s, although not overlord of Northumbria as his father had been. In 674, he challenged Oswiu's son Ecgfrith of Northumbria, but was defeated. He died, probably of disease, in 675. Wulfhere was succeeded as King of Mercia by his brother, Æthelred. Stephen of Ripon's Life of Wilfrid describes Wulfhere as "a man of proud mind, and insatiable will".

England in AD 600 was ruled almost entirely by the Anglo-Saxon peoples who had come to Britain from northwestern Europe over the previous 200 years. The monk Bede, writing in about AD 731, considered the Mercians to be descended from the Angles, one of the invading groups; the Saxons and Jutes settled in the south of Britain, while the Angles settled in the north. Little is known about the origins of the kingdom of Mercia, in what is now the English Midlands, but according to genealogies preserved in the Anglo-Saxon Chronicle and the Anglian collection the early kings were descended from Icel; the dynasty is therefore known as the Iclingas. The earliest Mercian king about whom definite historical information has survived is Penda of Mercia, Wulfhere's father.

According to Bede's Historia ecclesiastica gentis Anglorum, a history of the English church, there were seven early Anglo-Saxon rulers who held imperium, or overlordship, over the other kingdoms. The fifth of these was Edwin of Northumbria, who was killed at the Battle of Hatfield Chase by a combined force including Cadwallon, a British king of Gwynedd and Penda. At the time of this victory, Penda was probably not yet king of Mercia. His children included two future kings of Mercia: Wulfhere and Æthelred.

After Edwin's death, Northumbria briefly fell apart into its two constituent kingdoms - Bernicia and Deira. Within a year Oswald killed Cadwallon and reunited the kingdoms, and subsequently re-established Northumbrian hegemony over the south of England. However, on 5 August 642, Penda killed Oswald at the Battle of Maserfield, probably at Oswestry in the northwest midlands. Penda is not recorded as overlord of the other southern Anglo-Saxon kings, but he became the most powerful of the Anglo-Saxon kings after he defeated Oswald. On Oswald's death, Northumbria was divided again: Oswald's son Oswiu succeeded to the throne of Bernicia, and Osric's son Oswine to Deira, the southern of the two kingdoms.

The main source for this period is Bede's History, completed in about 731. Despite its focus on the history of the church, this work also provides valuable information about the early pagan kingdoms. For other kingdoms than his native Northumbria, such as Wessex and Kent, Bede had an informant within the ecclesiastical establishment who supplied him with additional information. This does not seem to have been the case with Mercia, about which Bede is less informative than about other kingdoms. Further sources for this period include the Anglo-Saxon Chronicle, compiled at the end of the 9th century in Wessex. The Chronicle's anonymous scribe appears to have incorporated much information recorded in earlier periods.

Wulfhere was the son of Penda of Mercia. Penda's queen, Cynewise, is named by Bede, who does not mention her children; no other wives of Penda are known and so it is likely but not certain that she was Wulfhere's mother. The Anglo-Saxon Chronicle gives Penda's age as fifty in 626, and credits him with a thirty-year reign, but this would put Penda at eighty years old at the time of his death, which is generally thought unlikely as two of his sons (Wulfhere and Æthelred) are recorded as being young when he was killed. It is thought at least as likely that Penda was 50 years old at his death, rather than at his accession. Wulfhere's date of birth is unknown, but Bede describes him as a youth at the time of his accession in 658, so it is likely he was in his middle teens at that time; Penda would then have been in his thirties at the time Wulfhere was born.
