34. Celtic Britain might have been safe- if King Cogidubnus of the Atrebates had not sold out to the Romans
In 43 BC, Emperor Claudius succeeded whereas Julius Caesar failed by successfully invading Celtic Britain. The emperor’s troops landed on the south coast and after beating back resistance, established their capital at Camulodunum. Claudius’s invasion succeeded because the Romans had already gained a foothold in Britain by winning over some southern tribes. Key to their campaign was King Cogidubnus of the Atrebates. Cogidubnus loved all things Roman, and so he sold out to the Romans, allowing them to build military bases in Atrebate territory where they could mass troops and cavalry. His reward was riches not seen again in Britain until the middle ages.
