The Romans ruled Britain for about 350 years.
The Romans first invaded Britain in 55 BC. In 43 AD they officially annexed it. In this nearly 100 year span, Romans were living in and trading with Britain.
The only enemies who were forced to become allies of the Romans were the Samnite and Lucanians of southern Italy. The Romans could do so because they defeated them. All the other alliances Rome had were not with enemies. They were with peoples who decided to become friends and allies of Rome.
