About the Early Medieval Period

The early medieval period saw the collapse of Roman authority and the emergence of Anglo-Saxon kingdoms across what became England. Viking raids from the late eighth century onwards reshaped the political landscape, creating the Danelaw and fuelling the resistance of Alfred the Great. The period closes with the Norman Conquest of 1066 — itself set in motion by battles at Fulford Gate, Stamford Bridge, and Hastings in a single extraordinary year.
