Mercia was an early medieval Anglo-Saxon kingdom, one of the seven kingdoms of the Anglo-Saxon period. It was centred on the River Trent and its tributaries, in a region now known as the Midlands of England.
The royal court moved around the kingdom without a fixed capital city. Early in its existence Repton seems to have been the location of an important royal estate. According to the Anglo-Saxon Chronicle, the Great Heathen Army deposed the King of Mercia from Repton in 873–874. Slightly earlier, King Offa seems to have favoured Tamworth. He was crowned there, and Tamworth is where he resided during multiple Christmases.
For the three centuries between 600 and 900, known as Mercian Supremacy or the "Golden Age of Mercia", having annexed or gained submissions from five of the other six kingdoms of the Heptarchy (East Anglia, Essex, Kent, Sussex and Wessex), Mercia dominated England south of the Humber estuary. During King Offa's reign, a dyke was created as the boundary between Mercia and the Welsh kingdoms. Nicholas Brooks noted that "the Mercians stand out as by far the most successful of the various early Anglo-Saxon peoples until the later ninth century", and some historians, such as Sir Frank Stenton, believe the unification of England south of the Humber estuary was achieved during Offa's reign.
King Peada converted to Christianity around 656. The Diocese of Mercia was founded in this year, with the first bishop (Diuma) based at Repton. The religion was firmly established in the kingdom by the late 7th century. After 13 years at Repton, in 669, Saint Chad (the fifth bishop) moved the bishopric to Lichfield and, in 691, the Diocese of Mercia became the Diocese of Lichfield. There has been a diocese based in the city ever since. For a brief period between 787 and 799 or 803 the diocese was an archbishopric. The current bishop, Michael Ipgrave, is the 99th since the diocese was established.
At the end of the 9th century, following the invasions of the Vikings and their Great Heathen Army, Danelaw absorbed much of the former Mercian territory. Danelaw at its height included London, all of East Anglia and most of the North of England.
The final Mercian king, Ceolwulf II, died in 879 with the kingdom appearing to have lost its political independence. Initially, it was ruled by a lord or ealdorman under the overlordship of Alfred the Great, who styled himself "King of the Anglo-Saxons". The kingdom had a brief period of independence in the mid-10th century and in 1016, by which time it was viewed as a province with temporary independence. Wessex conquered and united all the kingdoms into the Kingdom of England. The kingdom became an earldom until 1071.
History
Early history
Mercia's exact evolution at the start of the Anglo-Saxon era remains more obscure than that of Northumbria, Kent, or even Wessex. Mercia developed an effective political structure and was Christianised later than the other kingdoms. Archaeological surveys show that Angles settled the lands north of the River Thames by the 6th century. The name "Mercia" is Mercian Old English for "boundary folk" (see Welsh Marches), and the traditional interpretation is that the kingdom originated along the frontier between the native Brythonic-speaking Romano-British Welsh and the Anglo-Saxon invaders. However, Peter Hunter Blair argued an alternative interpretation: that they emerged along the frontier between Northumbria and the inhabitants of the Trent river valley.
Although its earliest boundaries remain obscure, a general agreement persists that the territory that was called "the first of the Mercians" in the Tribal Hidage covered much of south Derbyshire, Leicestershire, Nottinghamshire, Northamptonshire, Staffordshire and northern Warwickshire.
The earliest person named in any records as a king of Mercia is Creoda, said to have been the great-grandson of Icel. Coming to power around 584, he built a fortress at Tamworth which became the seat of Mercia's kings. His son Pybba succeeded him in 593. Cearl, a kinsman of Creoda, followed Pybba in 606; in 615, Cearl gave his daughter Cwenburga in marriage to Edwin, king of Deira, whom he had sheltered while he was an exiled prince.
The Mercian kings were the only Anglo-Saxon Heptarchy ruling house known to claim a direct family link with a pre-migration Continental Germanic monarchy.
Penda and the Mercian Supremacy
The next Mercian king, Penda, ruled from about 626 or 633 until 655. Some of what is known about Penda comes from the hostile account of Bede, who disliked him – both as an enemy to Bede's own Northumbria and as a pagan. However, Bede acknowledges that Penda freely allowed Christian missionaries from Lindisfarne into Mercia and did not restrain them from preaching. In 633 Penda and his ally Cadwallon of Gwynedd defeated and killed Edwin, who had become not only ruler of the newly unified Northumbria, but bretwalda, or high king, over the southern kingdoms. When another Northumbrian king, Oswald, arose and again claimed overlordship of the south, he too was defeated and killed at the hands of Penda and his allies – in 642 at the Battle of Maserfield. In 655, after a period of confusion in Northumbria, Penda brought 30 sub-kings to fight the new Northumbrian king Oswiu at the Battle of Winwaed, in which Penda in turn lost the battle and his life.
The battle led to a temporary collapse of Mercian power. Penda's son Peada, who had converted to Christianity at Repton in 653, succeeded his father as king of Mercia; Oswiu set up Peada as an under-king; but in the spring of 656 he was murdered and Oswiu assumed direct control of the whole of Mercia. A Mercian revolt in 658 threw off Northumbrian domination and resulted in the appearance of another son of Penda, Wulfhere, who ruled Mercia as an independent kingdom (though he apparently continued to render tribute to Northumbria for a while) until his death in 675. Wulfhere initially succeeded in restoring the power of Mercia, but the end of his reign saw a serious defeat by Northumbria. The next king, Æthelred, defeated Northumbria in the Battle of the Trent in 679, settling once and for all the long-disputed control of the former kingdom of Lindsey. Æthelred was succeeded by Cœnred, son of Wulfhere; both these kings became better known for their religious activities than anything else, but the king who succeeded them in 709, Ceolred, is said in a letter of Saint Boniface to have been a dissolute youth who died insane. So ended the rule of the direct descendants of Penda.
At some point before the accession of Æthelbald in 716 the Mercians conquered the region around Wroxeter, known to the Welsh as Pengwern or as "The Paradise of Powys". Elegies written in the persona of its dispossessed rulers record the sorrow at this loss.
The next important king of Mercia, Æthelbald, reigned from 716 to 757. For the first few years of his reign he had to face two strong rival kings, Wihtred of Kent and Ine of Wessex. But when Wihtred died in 725, and Ine abdicated in 726 to become a monk in Rome, Æthelbald was free to establish Mercia's hegemony over the rest of the Anglo-Saxons south of the Humber. Æthelbald suffered a setback in 752, when the West Saxons under Cuthred defeated him, but he seems to have restored his supremacy over Wessex by 757.
In July 2009, the Staffordshire Hoard of Anglo-Saxon gold was discovered by Terry Herbert in a field at Hammerwich, near Brownhills and close to Lichfield in Staffordshire. Lichfield functioned as the religious centre of Mercia. The artefacts have tentatively been dated by Svante Fischer and Jean Soulat to the 7th–8th centuries. Whether the hoard was deposited by Anglo-Saxon pagans or Christians remains unclear, as does the purpose of the deposit.
Reign of Offa and rise of Wessex
After the murder of Æthelbald by one of his bodyguards in 757, a civil war broke out which concluded with the victory of Offa, a descendant of Pybba. Offa (reigned 757 to 796) had to build anew the hegemony which his predecessor had exercised over the southern English, and he did this so successfully that he became the greatest king Mercia had ever known. Not only did he win battles and dominate Southern England, but also he took an active hand in administering the affairs of his kingdom, founding market towns and overseeing the first major issues of gold coins in Britain; he assumed a role in the administration of the Catholic Church in England (sponsoring the short-lived archbishopric of Lichfield, 787 to 799), and even negotiated with Charlemagne as an equal. Offa is credited with the construction of Offa's Dyke, which marked the border between Wales and Mercia.
Offa exerted himself to ensure that his son Ecgfrith of Mercia would succeed him, but after Offa's death in July 796 Ecgfrith survived for only five months, and the kingdom passed to a distant relative named Coenwulf in December 796. In 821 Coenwulf's brother Ceolwulf succeeded to the Mercian kingship; he demonstrated his military prowess by his attack on and destruction of the fortress of Deganwy in Gwynedd. The power of the West Saxons under Egbert (King of Wessex from 802 to 839) grew during this period, however, and in 825 Egbert defeated the Mercian king Beornwulf (who had overthrown Ceolwulf in 823) at Ellendun.
The Battle of Ellendun proved decisive. At this point, Mercia lost control of Kent, Sussex, Surrey, and possibly also Essex. Beornwulf was slain while suppressing a revolt amongst the East Angles, and his successor, a former ealdorman named Ludeca (reigned 826–827), met the same fate. Another ealdorman, Wiglaf, subsequently ruled for less than two years before Egbert of Wessex drove him out of Mercia. In 830 Wiglaf regained independence for Mercia, but by this time Wessex had clearly become the dominant power in England. Circa 840 Beorhtwulf succeeded Wiglaf.
Arrival of the Danes
In 852, Burgred came to the throne, and with Ethelwulf of Wessex subjugated North Wales. In 868 Danish invaders occupied Nottingham. The Danes drove Burgred from his kingdom in 874 and Ceolwulf II took his place. In 877 the Danes seized the eastern part of Mercia, which became part of the Danelaw. Ceolwulf, the last king of Mercia, left with the western half, reigned until 879. From about 883 until his death in 911 Æthelred, Lord of the Mercians, ruled Mercia under the overlordship of Wessex. Alfred changed his title from 'king of the West Saxons' to 'king of the Anglo-Saxons' to reflect the acceptance of his overlordship of all southern England not under Danish rule. All coins struck in Mercia after the disappearance of Ceolwulf in c. 879 were in the name of the West Saxon king. Æthelred had married Æthelflæd (c. 870 – 12 June 918), daughter of Alfred the Great of Wessex (r. 871–899), and she assumed power when her husband became ill at some time in the last ten years of his life.
After Æthelred's death in 911 Æthelflæd ruled as "Lady of the Mercians", but Alfred's successor as King of the Anglo-Saxons, Edward the Elder (r. 899–924), took control of London and Oxford, which Alfred had placed under Æthelred's control. Æthelflæd and her brother continued Alfred's policy of building fortified burhs, and by 918 they had conquered the southern Danelaw in East Anglia and Danish Mercia.
Loss of independence
When Æthelflæd died in 918, Ælfwynn, her daughter by Æthelred, succeeded as "Second Lady of the Mercians", but within six months Edward had deprived her of all authority in Mercia and taken her to Wessex. Edward was succeeded as king of the Anglo-Saxons by his eldest son Æthelstan (r. 924–939), who had been brought up in Mercia, and he was immediately accepted as king, but not in Wessex until the following year. In 927 he conquered Northumbria and thus became the first king of all England. Mercia briefly regained a political existence separate from Wessex in 955–959, when Edgar became king of Mercia, and again in 1016, when Cnut and Edmund Ironside divided the English kingdom between themselves, with Cnut taking Mercia. Mercia maintained its separate identity as an earldom until the Norman Conquest in 1066.
Mercian Old English
The name 'Mercia' is a Latinisation of an Old English word derived from the Mercian Old English, Merce, meaning "borderland". The dialect thrived between the 8th and 13th centuries and was referred to by John Trevisa, writing in 1387:
For men of the est with men of the west, as it were undir the same partie of hevene, acordeth more in sownynge of speche than men of the north with men of the south, therfore it is that Mercii, that beeth men of myddel Engelond, as it were parteners of the endes, understondeth better the side langages, northerne and southerne, than northerne and southerne understondeth either other...
J. R. R. Tolkien is one of many scholars who have studied and promoted the Mercian dialect of Old English and introduced various Mercian terms into his legendarium – especially in relation to the Kingdom of Rohan, otherwise known as the Mark (a name cognate with Mercia). The Mercian dialect is the basis of Tolkien's language of Rohan, and a number of its kings are given the same names as monarchs who appear in the Mercian royal genealogy, e.g., Fréawine, Fréaláf and Éomer (see List of kings of the Angles).
Mercian prose
During the ninth century, Mercia was a major centre for the production of Old English prose texts, including translations of Bede's Ecclesiastical History, Felix's Life of Guthlac and Gregory the Great's Dialogues, as well as works such as the Old English Martyrology.
Mercian religion
The first kings of Mercia were pagans, and they resisted the encroachment of Christianity longer than other kingdoms in the Anglo-Saxon Heptarchy.
Mercian rulers remained resolutely pagan until the reign of Peada in 656, although this did not prevent them joining coalitions with Christian Welsh rulers to resist Northumbria. The first appearance of Christianity in Mercia, however, had come at least thirty years earlier, following the Battle of Cirencester of 628, when Penda incorporated the formerly West Saxon territories of Hwicce into his kingdom.
The conversion of Mercia to Christianity occurred in the latter part of the 7th century, and by the time of Penda's defeat and death, Mercia was largely surrounded by Christian states. Diuma, an Irish monk and one of Oswiu's missionaries, was subsequently ordained a bishop – the first to operate in Mercia. Christianity finally gained a foothold in Mercia when Oswiu supported Peada as sub-king of the Middle Angles, requiring him to marry Oswiu's daughter, Alchflaed, and to accept her religion.
