England became inhabited more than 800000 years ago as the discovery of flint tools and footprints at Happisburgh in Norfolk has revealed.The earliest evidence for early modern humans in North West Europe a jawbone discovered in Devon at Kents Cavern in 1927 was re-dated in 2011 to between 41000 and 44000 years old. Continuous human habitation in England dates to around 13000 years ago (see Creswellian) at the end of the last glacial period. The region has numerous remains from the Mesolithic Neolithic and Bronze Age such as Stonehenge and Avebury. In the Iron Age England like all of Britain south of the Firth of Forth was inhabited by the Celtic people known as the Britons including some Belgic tribes (e.g. the Atrebates the Catuvellauni the Trinovantes etc.) in the south east. In AD 43 the Roman conquest of Britain began; the Romans maintained control of their province of Britannia until the early 5th century.

The end of Roman rule in Britain facilitated the Anglo-Saxon settlement of Britain which historians often regard as the origin of England and of the English people. The Anglo-Saxons a collection of various Germanic peoples established several kingdoms that became the primary powers in present-day England and parts of southern Scotland.[3] They introduced the Old English language which largely displaced the previous British language. The Anglo-Saxons warred with British successor states in Wales Cornwall and the Hen Ogledd (Old North; the Brythonic-speaking parts of northern England and southern Scotland) as well as with each other. Raids by Vikings became frequent after about AD 800 and the Norsemen settled in large parts of what is now England. During this period several rulers attempted to unite the various Anglo-Saxon kingdoms an effort that led to the emergence of the Kingdom of England by the 10th century.
