This timeline traces the key events in the history of the UK, from ancient times through its rise as a global superpower and into the modern era.
Prehistoric and Roman Britain (circa 8000 BCE – 410 CE)
Early Human Settlement (circa 8000 BCE – 2000 BCE)
The history of Britain begins in prehistoric times, with evidence of human habitation as early as the Paleolithic period:
- The first modern humans (Homo sapiens) arrived in Britain around 8000 BCE after the end of the last Ice Age.
- Neolithic peoples constructed monumental structures like Stonehenge and Avebury during this period, indicating the development of complex societies and religious practices.
- Bronze Age (circa 2500 BCE) and Iron Age (circa 800 BCE) cultures developed, marked by the emergence of tribal societies and early metalworking.
Celtic Tribes and Early Kingdoms (600 BCE – 43 CE)
By the 6th century BCE, the island was home to Celtic tribes, known for their warrior culture and intricate art forms:
- These tribes established early kingdoms and hill forts, particularly in southern and western Britain.
- Celtic languages, which survive today in Welsh, Scottish Gaelic, and Irish, dominated the island.
Roman Conquest and Occupation (43 CE – 410 CE)
The Romans invaded Britain under Emperor Claudius in 43 CE, beginning almost four centuries of Roman rule:

Viking Invasions and the Danelaw (800 CE – 1066 CE)
Starting in the late 8th century, Viking raids began to devastate Anglo-Saxon England:
- Viking warriors from Scandinavia conducted frequent raids, eventually leading to settlements in the north and east of England, known as the Danelaw.
