At this time on the Icenian throne was a king by the name of Antedious. He had made a treaty with Rome and had become a client state or client kingdom since the invasion.
A client state or a client kingdom was a state or kingdom under Roman Control. However the king or leader of this state or kingdom remained in power after the Romans had conquered them or the Enemy had submitted to their supreme fighting force which was said to be the best in the world at the time. This meant that the Roman empire would find it eayser to control the citizens or people of that state or kingdom, the King or leader of that state would still have some independence but the would awnser to Rome. It was important that the Iceni were a client state as they controlled the sea routes into the wash. .
The Romans were using the Iceni to control themselves! I think that this is a bit ironic because they also had to pay tributes to Rome for this privilege. This must have angered the Iceni and they would have thought that they were being used.
The Iceni were situated in the east of Britain and had borders with the Cativenllani and the Trinobantes (see map on the top right) both the Cativenllani and the Trinobantes had important trade links with the Roman Empire. However the Iceni tribe refused to play any part in this. The Iceni by doing this were going to be in for a big shock later on when they were forced to play a part in Roman culture etc. by excluding themselves from roman culture I think that they weren't doing themselves any favours.
Evidence gathered from the Roman pottery backs this idea up. The jugs on the left were called amphoras or amphorai in Latin, have been found all over Britain. These jugs were made in the Roman Empire and would have contained wine. However very few of these jugs have been found where the Iceni used to be situated compared with other places such as South Britain, where hundreds of these jugs were found.
