Stonehenge and other examples of prehistoric culture are all that remain of the earliest inhabitants of Britain. Celtic peoples followed. Roman invasions of the 1st century B.C. brought Britain into contact with continental Europe. When the Roman legions withdrew in the 5th century A.D. , Britain fell easy prey to the invading hordes of Angles, Saxons, and Jutes from Scandinavia and the Low Countries. The invasions had little effect on the Celtic peoples of Wales and Scotland. Seven large Anglo-Saxon kingdoms were established, and the original Britons were forced into Wales and Scotland. It was not until the 10th century that the country finally became united under the kings of Wessex. Following the death of Edward the Confessor (1066), a dispute about the succession arose, and William, Duke of Normandy, invaded England, defeating the Saxon king, Harold II, at the Battle of Hastings (1066). The Norman conquest introduced Norman French law and feudalism.
