What places in Britain were taken over by the Romans?

The Romans invaded Britain in AD 43 and established control over much of the island. Key areas included modern-day England, particularly the southeast, where they founded cities such as London (Londinium), Bath (Aquae Sulis), and York (Eboracum). They also extended their influence into Wales and parts of northern England and southern Scotland, although their control fluctuated over time. The Romans constructed extensive roads, forts, and Hadrian's Wall to defend their territory from the tribes in the north.
