In 55–54 BC, Julius Caesar arrived on the shores of Britain, but thanks to guerrilla resistance and bad weather, his conquest was not successful. Almost 100 years later, in AD 43 the emperor Claudius launched a full-scale invasion, and Britain’s Roman era began.
The Romans stayed in Britain for almost four centuries. In some parts of the country they were met with rebellion and resistance, but in more peaceful areas cities were founded, villas constructed and a network of roads developed that can still be traced today. And in AD 122, the emperor Hadrian, visiting Britain, ordered the building of his famous wall.
