Which Roman emperor launched the conquest of Britain in 43 CE?

Roman emperor Claudius launched the conquest of Britain in 43 CE.

The invasion followed earlier Roman expeditions by Julius Caesar in 55 and 54 BCE, but those campaigns did not establish a permanent Roman province. Claudius sent a large force under the general Aulus Plautius, and the invasion provided the emperor with a major military triumph and political prestige.

Claudius briefly travelled to Britain after the initial victories and received the submission of several local rulers. Rome gradually extended control over much of present-day England and Wales, although resistance continued for decades.

The conquest was not completed in a single campaign. Boudica’s revolt in 60 or 61 CE caused severe destruction in Roman Britain, while northern Britain remained contested. Roman rule ended in the early fifth century as imperial forces withdrew.
