Mercia

history Maturity 11-13 Next article →

Mercia was a powerful early medieval English kingdom. It was one of the seven kingdoms of the Anglo-Saxon period. The kingdom was centered on the River Trent and its many tributaries. Most of this land is in the region we now call the Midlands. The name "Mercia" comes from Mercian Old English. It likely means "boundary folk." This suggests the kingdom formed along a frontier. Some historians believe it was a border between the Welsh and the Anglo-Saxons. Others suggest it was a border between Northumbria and the Trent river valley.

Unlike many modern nations, Mercia had no single fixed capital city. The royal court moved around the kingdom instead. Some locations were more important than others. Tamworth was a major seat for the kings. King Creoda, who rose to power around 584, built a fortress there. King Offa also favored Tamworth for his residence. Repton was another vital location. It served as an important royal estate for many years. The Great Heathen Army even deposed the King of Mercia from Repton in 873–874.

Religion transformed the Mercian way of life. In 656, King Peada converted to Christianity. This led to the creation of the Diocese of Mercia. The first bishop was a man named Diuma. He was based at Repton. By the late 7th century, Christianity was firmly established. In 669, Saint Chad moved the bishopric to Lichfield. This made Lichfield the religious center of the kingdom. In 691, the diocese became the Diocese of Lichfield. For a short time between 787 and 799, it even served as an archbishopric.

Between the years 600 and 900, Mercia experienced a "Golden Age." This era is often called the Mercian Supremacy. During this time, Mercia dominated England south of the Humber estuary. The kingdom gained control or submission from five other kingdoms. These included East Anglia, Essex, Kent, Sussex, and Wessex. King Penda was a major figure in this early era. He ruled from roughly 626 or 633 until 655. He was a warrior king who fought many battles against Northumbria.

King Offa was perhaps the greatest leader in Mercian history. He reigned from 757 to 796. Offa was a very successful administrator. He founded market towns and oversaw the first major issues of gold coins in Britain. He even negotiated with the famous leader Charlemagne as an equal. Offa is also known for building Offa's Dyke. This was a massive boundary between Mercia and the Welsh kingdoms. His reign showed how much influence a Mercian king could hold.

Changes in power eventually led to the decline of the kingdom. In the 9th century, the Great Heathen Army arrived. These were Viking invaders who changed the map of England. The Danes seized much of Mercian territory. This area became part of the Danelaw. At its highest point, the Danelaw included London and East Anglia. The last king of Mercia was Ceolwulf II. He died in 879, and the kingdom lost its political independence. After this, Mercia was often ruled by lords under the kings of Wessex.

By 1016, the era of separate kingdoms was ending. Wessex conquered and united all the kingdoms into the Kingdom of England. Mercia became a province and later an earldom until 1071. We still learn about this period through amazing discoveries. In 2009, a massive collection of gold objects was found in Staffordshire. This is known as the Staffordshire Hoard. It was found near Lichfield in a field. These objects help us understand the wealth and art of the Anglo-Saxon people.
