The Romans conquered Britain over 2000 years ago. They were attracted by resources and wanted to stop British aid to their enemies in Gaul. Under Julius Caesar and later Emperor Claudius, the Romans established control over southern Britain and built roads, towns, and walls. However, resistance continued in northern and western Britain. A major rebellion led by Boudica destroyed Roman towns before being defeated. Over centuries of rule, Roman culture influenced the Britons through language, religion, architecture and urban life. The Romans withdrew from Britain in the 5th century, leaving a lasting legacy.
