Pre-Roman Britain saw various Celtic groups migrate to and settle the islands. The Romans then invaded in 43 AD and governed Britain for over 300 years. After the Romans left in 410 AD, Anglo-Saxon tribes were invited to defend against Pictish and Scottish raids and eventually dominated most of England, establishing the kingdom of England. The Vikings then began invading in the 9th century, with many battles between the Danes and Anglo-Saxons before Alfred the Great of Wessex defeated the Danes in the late 9th century. The Norman conquest of 1066 established a strong monarchy and feudal system in England.
