What order did the groups of people appear in England?

In England, the chronological order of significant groups includes the Celts, who were the earliest known inhabitants, followed by the Romans who invaded in AD 43. After the Roman withdrawal in the early 5th century, the Anglo-Saxons arrived, establishing their kingdoms. Later, the Vikings launched raids and settled in parts of England, and finally, the Normans invaded in 1066, marking a significant shift in English history.
