Long ago, there was a land called Northumbria. 
Long ago, a land called Northumbria grew.
Two kings fought for a long time. Then, one king joined them. Now, the two lands were one.
Later, new people came from far away. These people were called Vikings. They attacked a place called Lindisfarne. 
The Vikings took some of the land. They made a new kingdom in York. This changed how the land was ruled.
Many years passed. The old kingdom changed into new parts. It is fun to learn about old lands! 
Northumbria was a kingdom in early England.
At first, Northumbria was two separate lands. One was called Bernicia in the north. The other was Deira in the south. They often fought each other. In 651, the kings joined the lands together. One king ruled them as one.
Later, new people came to the area. These were the Vikings. They began raiding in the year 793. They attacked a place called Lindisfarne. 
In 866, a large group called the Great Heathen Army arrived. They took control of York. This split the land again. The Vikings made the Kingdom of York. They ruled the southern parts. In the north, English leaders still held some power. 
Eventually, the old kingdom changed. It became parts of Scotland and England. It is amazing to see how lands change over time.
Northumbria was a powerful kingdom in early medieval England. It lasted from the year 654 until 1066. The name means the people living north of the Humber River.
In the beginning, Northumbria was actually two separate kingdoms. One was named Bernicia in the north. The other was called Deira in the south. They were often at war with one another. The two lands finally joined together in 651. This happened after the last king of Deira was killed. From then on, kings from Bernicia ruled the whole unified land. 
History tells us about the people who lived there first. It is possible that native British people lived in these areas. We know this because some place names sound British. For example, a hill fort called Yeavering Bell shows signs of very old settlements. 
New groups of people arrived and changed the kingdom forever. In 793, Viking raiders attacked the holy island of Lindisfarne. 

Over many years, the borders of Northumbria kept shifting. The land north of the River Tweed became part of Scotland. The land south of the river became part of England. It became the counties of Northumberland and Durham. 
Northumbria was a significant Anglo-Saxon kingdom in early medieval England. It existed from 654 AD until 1066 AD. The name comes from Old English words meaning "the people north of the Humber."
Before it was one kingdom, the region consisted of two separate states. These were Bernicia in the north and Deira in the south. The River Tees served as a rough boundary between them. Bernicia's power centers included areas like Bamburgh, Lindisfarne, and Carlisle. Deira's political heartland was located in the East Riding of Yorkshire, including the important city of York. 
Archaeological evidence suggests the land had deep roots before the Anglo-Saxons arrived. It is possible that native Celtic British kingdoms existed in these areas first. We see clues of this in many regional place names. For example, the name Yeavering likely comes from the British word "gefrin." 
The unification of the two kingdoms was a long and often violent process. In the mid-seventh century, the two states were frequently in conflict. A king named Æthelfrith was the first to rule both Bernicia and Deira. Later, King Edwin ruled both kingdoms from 616 to 633 AD. 
In the late eighth century, the kingdom faced a new and massive challenge from Viking invaders. In 793 AD, a band of raiders attacked the holy island of Lindisfarne. This event marked the beginning of significant Viking activity in the region. 
The Viking invasions eventually split the old kingdom into two distinct parts. The Norse established the Kingdom of York in the southern provinces. This kingdom covered the area between the River Tees and the Humber. It lasted until 954 AD, when the last Scandinavian king, Eric, was driven out. 
As the era of independent Northumbrian kings ended, the land was divided by new borders. The territory north of the River Tweed was eventually absorbed into the Kingdom of Scotland. The area south of the Tweed became part of the Kingdom of England. This southern portion was organized into the county of Northumberland and the County Palatine of Durham.
