British History

Roman Britain, AD 43–early fifth century

Rome conquered much of Britain after AD 43, creating towns, roads, forts and systems of taxation. Provincial society combined local traditions with practices drawn from across the empire; it was never simply a contest between 'Romans' and 'Britons'.

Anglo-Saxon kingdoms and Viking settlement

After Roman government ended, political authority became more local and new kingdoms developed. Migration from the North Sea world, Christian conversion and later Viking raiding and settlement reshaped language, landholding and power. By the tenth century, kings of Wessex and their successors ruled a kingdom recognisable as England.

The Norman Conquest and the medieval kingdoms

William of Normandy's victory in 1066 replaced much of England’s ruling elite and connected England more closely to continental Europe. England, Scotland and Wales remained separate political communities. English rulers conquered Wales and repeatedly tried to extend their power in Scotland and Ireland, meeting resistance in each.

Tudor England and Wales

The Tudor period brought disputed successions, Henry VIII’s break with Rome and repeated changes to official religion. Laws passed under Henry VIII joined England and Wales more closely under one system of government. The English state also expanded its war and colonisation in Ireland, which belongs to the connected but distinct history of English rule in Ireland.

Stuart rule and civil war

James VI of Scotland inherited the English throne in 1603, so one monarch ruled separate kingdoms. Disputes over taxation, religion and royal power contributed to wars in England, Scotland and Ireland. Charles I was executed in 1649, the monarchy returned in 1660, and the events of 1688–89 placed clearer limits on royal power without creating modern democracy.

Great Britain, the United Kingdom and empire

The 1707 Acts of Union joined England and Scotland in the Kingdom of Great Britain. A further union in 1801 created the United Kingdom of Great Britain and Ireland. Trade, slavery, colonial expansion and warfare increased the state’s power and wealth, but the gains and costs were shared very unequally in Britain, Ireland and overseas.

Industrial and Victorian Britain

Industrialisation transformed work, cities, transport and the environment in Britain. Reform Acts gradually gave more men the vote, while campaigners challenged unsafe work, overcrowding and inequality. Ireland was then part of the United Kingdom but had a distinct experience of British rule; the Great Famine and its political consequences are explained fully in the Irish History guide.

World wars and mass democracy

The world wars required unprecedented mobilisation and drew on troops and resources from across the empire. The Representation of the People Acts of 1918 and 1928 created near-universal adult suffrage. After 1945, welfare reform, the National Health Service and nationalisation changed the relationship between citizen and state.

Decolonisation, migration and modern Britain

Indian independence in 1947 was followed by the end of most formal British colonial rule. Migration from the Caribbean, South Asia, Africa and elsewhere changed British society, while racism and disputes over citizenship shaped migrants’ lives. Devolution created separate legislatures in Scotland and Wales, while the history and politics of Northern Ireland remained distinct within the United Kingdom.

Key developments and why they matter

AD 43 marks roman conquest began. The emperor Claudius's invasion established a province across much of Britain. 1066 marks norman conquest. William defeated Harold at Hastings and replaced the English ruling elite. These dates matter because each development grew from earlier events and changed what people could do next.

1215 marks magna carta. King John accepted a baronial peace settlement that was later repeatedly reissued and reinterpreted. 1534 marks act of supremacy. Henry VIII was recognised as supreme head of the Church of England. Reading these events together connects political decisions with changes in war, work and everyday life.

1642–1651 marks wars of the three kingdoms. Civil wars transformed England, Scotland and Ireland and led to the execution of Charles I. 1688–1689 marks bill of rights and a new political settlement. James II was displaced and the Bill of Rights limited key royal powers. Reading these events together connects political decisions with changes in war, work and everyday life.

1707 marks acts of union. The English and Scottish Parliaments created the Kingdom of Great Britain. 1801 marks united kingdom created. Great Britain and Ireland were joined in the United Kingdom of Great Britain and Ireland. Together, these later events show how British History developed over time and why its consequences lasted.

How historians explain this topic

A timeline shows what happened, but it does not explain every cause. To understand British History, historians compare political decisions, available resources, ideas and the experiences of people in different places.

Important questions include how and when did england, scotland and wales become part of one state; how did the political relationship between britain and ireland change over time; how did empire affect people in britain and in the places britain ruled. Answering them requires evidence, not just a list of dates or the actions of one famous person.
