The history of England concerns the study of the human past in one of Europe's oldest and most influential national territories. What is now England, a country within the United Kingdom, was inhabited by Neanderthals 230,000 years ago. Continuous human habitation dates to around 12,000 years ago, 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, but also by some Belgae 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 through to the 5th century.
