Mercia

• 1. Introduction

  ›

  Mercia was an early medieval English kingdom whose name meant, literally, "boundary folk" - people defined by the edges they occupied. For roughly three centuries, from around 600 to 900, Mercia dominated England south of the Humber estuary, annexing or receiving submissions from five of the six other Anglo-Saxon kingdoms. Yet it left no fixed capital, no royal city you could point to on a map. Its kings moved constantly through the land they controlled, holding court wherever the season demanded.

  Who were these borderland rulers, and how did a kingdom whose identity was built on frontiers become the most powerful force in early England? The answers move through warrior kings and pagan holdouts, Danish invaders and a remarkable woman who governed in her own name, and a dialect of Old English that shaped one of the most beloved fictional worlds of the twentieth century.

• 2. Kings of the Frontier

  ›

  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, and that site became the seat of Mercia's kings. His son Pybba succeeded him in 593. Cearl, a kinsman of Creoda, followed Pybba in 606, and in 615 he gave his daughter Cwenburga in marriage to Edwin, king of Deira - a man he had sheltered while Edwin was still an exiled prince.

  The Mercian kings carried one distinction no other Anglo-Saxon ruling house could claim: they alone traced a direct family link to a pre-migration Continental Germanic monarchy. This connection to an older, continental world set the Mercian royal genealogy apart from the start.

  The most formidable of the early kings was Penda, who ruled from about 626 or 633 until 655. Much of what survives about Penda comes from Bede, who disliked him as both a pagan and an enemy of Northumbria. Even Bede, however, admitted that Penda freely allowed Christian missionaries from Lindisfarne into Mercia and did not stop them from preaching. In 633, Penda and his ally Cadwallon of Gwynedd defeated and killed Edwin, who had become ruler of unified Northumbria and bretwalda - high king over the southern kingdoms. When the next Northumbrian king, Oswald, claimed the same overlordship, Penda and his allies defeated and killed him too, in 642 at the Battle of Maserfield.

  Penda's end came in 655. He brought thirty sub-kings to fight the Northumbrian king Oswiu at the Battle of Winwaed, and there he lost both the battle and his life. The kingdom briefly collapsed under Northumbrian pressure before Penda's son Wulfhere drove out the northerners in 658 and restored Mercian independence.

• 3. Offa and the Golden Age

  ›

  After the murder of King Æthelbald by one of his own bodyguards in 757, a civil war broke out that ended with the victory of Offa, a descendant of Pybba. Offa reigned from 757 to 796, and he transformed Mercia into something England had not seen before. He won battles across southern England, founded market towns, and oversaw the first major issues of gold coins in Britain.

  Offa took an active role in the Catholic Church, sponsoring the short-lived archbishopric of Lichfield, which ran from 787 to 799. He negotiated with Charlemagne as a political equal - an extraordinary position for any English ruler of the period. Historian Sir Frank Stenton and others have argued that the unification of England south of the Humber was effectively achieved during Offa's reign.

  The most enduring physical monument of his rule is Offa's Dyke, a boundary earthwork that marked the border between Mercia and the Welsh kingdoms. Nicholas Brooks wrote that "the Mercians stand out as by far the most successful of the various early Anglo-Saxon peoples until the later ninth century". That judgment rests heavily on what Offa built.

  Offa worked hard to secure the succession for his son Ecgfrith of Mercia. Ecgfrith survived his father by only five months after Offa's death in July 796, and the kingdom passed to a distant relative named Coenwulf in December 796. In July 2009, a farmer named Terry Herbert discovered the Staffordshire Hoard of Anglo-Saxon gold in a field at Hammerwich, near Brownhills in Staffordshire - not far from Lichfield, the religious centre of Mercia. Scholars Svante Fischer and Jean Soulat tentatively dated the artefacts to the 7th-8th centuries, placing them squarely in the era when Mercian power was at its height.

• 4. The Faith Takes Hold

  ›

  Mercia's first kings were pagans, and they held out against Christianity longer than any other kingdom in the Anglo-Saxon world. Crucially, this did not stop them from forming military alliances with Christian Welsh rulers when it suited their political interests.

  The first foothold Christianity gained in Mercian territory came not through royal conversion but through conquest. After the Battle of Cirencester in 628, Penda incorporated the formerly West Saxon territories of Hwicce into his kingdom - a region that was already Christian. The actual conversion of the Mercian royal line came when Oswiu of Northumbria supported Penda's son Peada as sub-king of the Middle Angles, requiring him to marry Oswiu's daughter Alchflaed and accept her religion. Peada had converted at Repton in 653.

  The Diocese of Mercia was established in 656, with an Irish monk named Diuma serving as its first bishop, based at Repton. After thirteen years there, in 669, Saint Chad became the fifth bishop and moved the bishopric to Lichfield, where it has been based ever since. Chad was given land by King Wulfhere to build a monastery there. Evidence suggests the Lichfield Gospels were produced in the city around 730.

  Chad was given a central role in formalising the new faith's administration across the region. The current bishop of the Diocese of Lichfield, Michael Ipgrave, is the 99th to hold the position since the diocese was established - a line of succession stretching back to Diuma in the year Mercia first accepted a bishop.

• 5. Æthelflæd and the Danish Reckoning

  ›

  Danish invaders occupied Nottingham in 868. By 874, they had driven King Burgred from his kingdom entirely. The last Mercian king, Ceolwulf II, took his place and reigned with the western half of Mercia until 879, when the eastern portion became part of the Danelaw. At its height, Danelaw included London, all of East Anglia, and most of the North of England.

  From about 883 until his death in 911, Æthelred, Lord of the Mercians, governed what remained under the overlordship of Alfred the Great of Wessex. Alfred adjusted his own title from "king of the West Saxons" to "king of the Anglo-Saxons" to reflect his authority over all of southern England not under Danish rule. Every coin struck in Mercia after Ceolwulf's disappearance around 879 bore the name of the West Saxon king.

  Æthelred had married Æthelflæd, born around 870, daughter of Alfred the Great. When Æthelred became ill in his final years, she assumed power. After his death in 911, she governed in her own right as "Lady of the Mercians". Together with her brother Edward the Elder, she continued Alfred's policy of building fortified settlements called burhs. By 918, they had conquered the southern Danelaw in East Anglia and recovered Danish Mercia.

  When Æthelflæd died on the 12th of June 918, her daughter Ælfwynn succeeded as "Second Lady of the Mercians". Within six months, Edward had stripped Ælfwynn of all authority and taken her to Wessex. Mercian independence, in any meaningful sense, was finished.

• 6. A Dialect Tolkien Loved

  ›

  The name Mercia is a Latinisation of the Old English word Merce, meaning "borderland". The dialect that developed in this region thrived between the 8th and 13th centuries. In 1387, John Trevisa described it this way: that the people of middle England, positioned between north and south, could understand both northern and southern speech better than northerners and southerners could understand each other.

  J. R. R. Tolkien is among the scholars who studied and promoted Mercian Old English, and he went further than study: he wove Mercian terms into his legendarium. The Kingdom of Rohan in his fiction, otherwise known as the Mark, takes its name from a word cognate with Mercia itself. Tolkien built the language spoken by the Riders of Rohan on the Mercian dialect, and several of its kings share names with monarchs from the actual Mercian royal genealogy, including Fréawine, Fréaláf, and Éomer.

  Tolkien scholar Tom Shippey has also argued that the Middle Kingdom in Tolkien's story Farmer Giles of Ham, whose central conflict involves a dragon named Chrysophylax, is based on Mercia - the part of England where Tolkien grew up. Shippey notes that "the Mark" was once the common term for central England, and in the Mercian dialect would have been written and pronounced "marc" rather than the West Saxon "mearc" or the Latinised "Mercia".

  Mercia was also, during the ninth century, a major centre for the production of Old English prose texts. Translations produced there included Bede's Ecclesiastical History, Felix's Life of Guthlac, Gregory the Great's Dialogues, and works such as the Old English Martyrology.

• 7. Symbols and Survival

  ›

  The gold-on-blue saltire that serves as Mercia's attributed heraldry has no authenticated ancient origin - heraldry as a recognisable system did not exist until the High Middle Ages. The saltire may have been associated with King Offa's era, but by the 13th century it had become the attributed arms of the kingdom. Offa founded the Abbey of St Albans, and that institution subsequently used the device; when the abbey was dissolved, the arms passed to the borough of St Albans and were formally recorded at a heraldic visitation in 1634.

  The wyvern, a type of legless dragon, became associated with Mercia through a more unusual route. The Midland Railway adopted a white wyvern from the Leicester and Swannington Railway and claimed it was the ancient standard of Mercia. The symbol appeared on railway stations across the region, and all uniformed employees wore it as a silver badge. In 1897, the Railway Magazine noted there appeared "to be no foundation that the wyvern was associated with the Kingdom of Mercia". Its actual origin traces to Thomas, 2nd Earl of Lancaster and Leicester, born around 1278 and died 1322, who used it as his personal crest - centuries after Mercia had ceased to exist as a kingdom.

  Bram Stoker drew on both strands of this symbolism in his 1911 novel The Lair of the White Worm, set explicitly in a contemporary Mercia. Stoker transformed the Midland Railway's white wyvern into the monstrous creature at the centre of his story.

  Today the saltire flies from Tamworth Castle, the ancient seat of Mercian kings, and appears on street signs welcoming visitors to the town. The Flag Institute formally recognised it as the Mercian flag in 2014. The Mercian Regiment, founded in 2007 and recruiting across Cheshire, Derbyshire, Nottinghamshire, Worcestershire, and parts of Greater Manchester and the West Midlands, carries the name forward in the British Army - a direct institutional descendant of the Mercian Brigade that existed from 1948 to 1968.
