Boadicea is probably the best known of the Celtic Queens. Referred to in ancient testaments as Boudicca, she was the wife of King Prasutagus of the Iceni tribe.
After the Roman invasion of Britain, Prasutagus became a `client` King, acknowledged by the Romans as a ruler but no longer with any real power. After his death in 60 A.D. Boadicea and her tribe were maltreated by the Romans, Boadicea herself was flogged, her daughters raped and their lands confiscated. Boadicea lead the Iceni in a rebellion against the Romans and with the help of the Celtic tribes along the way they sacked Colchester, even then a large town, and defeated the Ninth Legion; they then went on to sack Verulamium, now called St.Albans, and even London itself.
Their rebellion was only stopped after the majority of the Roman army was called back from campaigning in Wales to deal with them. After a heavy battle Boadiceas' troops were defeated, Boadicea took her own life by poison shortly afterwards.
It was the most serious rebellion that the Romans ever faced in Britain and came near to ending Roman domination after only seventeen years. Contempory reports suggest that on her rampage through the Roman towns Boadicea and her tribe were responsible for the death of 70,000 Romans.
