The Anglo-Saxons were a cultural group that inhabited much of what is now England in the Early Middle Ages, and spoke Old English. They traced their origins to Germanic settlers who came to Britain from mainland Europe in the 5th century. Although the details are not clear, their cultural identity developed out of the interaction of these settlers with the pre-existing Romano-British culture. Over time, most of the people of what is now southern, central, northern and eastern England came to identify as Anglo-Saxon and speak Old English. Danish and Norman invasions later changed the situation significantly, but their language and political structures are the direct predecessors of the medieval Kingdom of Engl and the Middle English language. Although the modern English language owes somewhat less than 26% of its words to Old English, this includes the vast majority of words used in everyday speech.
