The Iceni were a Celtic tribe who lived in Great Britain, in the area of modern-day Norfolk and Suffolk. Emperor Claudius invaded Great Britain in the year 43 AD. After that, the Iceni became allies of Rome. At that time, Antedios was the ruler of the Iceni. There was little economic exchange between the Iceni and the Romans: The Iceni feared a loss of cultural identity. This meant, that the Romans saw the relationship with the Iceni as a bad one. The Roman governor, Publius Ostorius Scapula, decided to disarm the tribes the Romans had bad relations with, in the year 47, and to build new Roman fortifications.
