The territory today known as England became inhabited more than 800,000 years ago, as the discovery of stone tools and footprints at Happisburgh in Norfolk have indicated. The earliest evidence for early modern humans in Northwestern Europe, a jawbone discovered in Devon at Kents Cavern in 1927, was re-dated in 2011 to between 41,000 and 44,000 years old. Continuous human habitation in England dates to around 13,000 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, 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. They introduced the Old English language, which largely displaced the previous Brittonic language. The Anglo-Saxons warred with British successor states in western Britain and the Hen Ogledd (Old North; the Brittonic-speaking parts of northern Britain), 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. In 1066, a Norman expedition invaded and conquered England. The Norman dynasty, established by William the Conqueror, ruled England for over half a century before the period of succession crisis known as the Anarchy (1135–1154). Following the Anarchy, England came under the rule of the House of Plantagenet, a dynasty which later inherited claims to the Kingdom of France. During this period, Magna Carta was signed and Parliament became established. Anti-Semitism rose to great heights, and in 1290, England became the first country to permanently expel the Jews.: 44–45 : 1  A succession crisis in France led to the Hundred Years' War (1337–1453), a series of conflicts involving the peoples of both nations. Following the Hundred Years' Wars, England became embroiled in its own succession wars between the descendants of Edward III's five sons. The Wars of the Roses broke out in 1455 and pitted the descendants of the second son (through a female line) Lionel of Antwerp known as the House of York against the House of Lancaster who descended from the third son John of Gaunt and his son Henry IV, the latter of whom had overthrown his cousin Richard II (the only surviving son of Edward III"s eldest son Edward the Black Prince) in 1399. In 1485, the war ended when Lancastrian Henry Tudor emerged victorious from the Battle of Bosworth Field and married the senior female Yorkist descendant, Elizabeth of York, uniting the two houses. Under the Tudors and the later Stuart dynasty, England became a colonial power. During the rule of the Stuarts, the English Civil War took place between the Parliamentarians and the Royalists, which resulted in the execution of King Charles I (1649) and the establishment of a series of republican governments—first, a Parliamentary republic known as the Commonwealth of England (1649–1653), then a military dictatorship under Oliver Cromwell known as the Protectorate (1653–1659). The Stuarts returned to the restored throne in 1660, though continued questions over religion and power resulted in the deposition of another Stuart king, James II, in the Glorious Revolution (1688). England, which had subsumed Wales in the 16th century under Henry VIII, united with Scotland in 1707 to form a new sovereign state called Great Britain. Following the Industrial Revolution, which started in England, Great Britain ruled a colonial Empire, the largest in recorded history. Following a process of decolonisation in the 20th century, mainly caused by the weakening of Great Britain's power in the two World Wars; almost all of the empire's overseas territories became independent countries.
