Long ago, Mercia was a powerful kingdom in England.
Many kings ruled Mercia. King Offa was one of the most famous. He ruled from 757 to 796. He was a very strong leader. He made gold coins for his people. He also built a long wall. This was called Offa's Dyke. It marked the border with Wales.
Mercia was also a place for religion. In the year 656, King Peada became a Christian. The kingdom built many churches. The city of Lichfield became a center for the church. 
Things changed in the late 800s. A group called the Vikings came to fight. They were known as the Great Heathen Army. They took much of the Mercian land. This area became part of the Danelaw. By the year 1016, Mercia was no longer a free kingdom. It was joined with other lands to make England.
Mercia was a major kingdom in early medieval England. It sat in a region we now call the Midlands. The kingdom grew around the River Trent and its many branches. Its name likely means "boundary folk." This is because it sat on a frontier between different groups.
Religion played a huge role in how Mercia worked. In 656, King Peada became a Christian. This led to the start of the Diocese of Mercia. The first bishop was named Diuma, and he stayed at Repton. Later, in 669, Saint Chad moved the center to Lichfield. 
Mercia had a very successful time known as the Mercian Supremacy. This lasted for three hundred years between 600 and 900. During this Golden Age, Mercia was the strongest land in the south. King Offa was the most famous leader of this era. He ruled from 757 to 796. He was so powerful that he even talked to leaders like Charlemagne as an equal.
Many kings fought to keep Mercia strong and independent. King Penda ruled for a long time starting around 626. He was a warrior who fought many battles against other kingdoms. Later, King Æthelbald ruled from 716 to 757. He worked hard to keep control over other Anglo-Saxon groups. Even with all these leaders, the kingdom faced many hard jobs. 
Eventually, the kingdom began to change forever. In the late 9th century, the Great Heathen Army arrived. These were Viking invaders who took much of the Mercian land. This area became part of the Danelaw. The last king was Ceolwulf II, who died in 879. After that, Mercia was ruled by leaders under the king of Wessex. By 1016, the different kingdoms were joined to form England. 
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.
