Boudicca was the queen of the Iceni tribe who led a major rebellion against Roman rule in AD 61 after the Romans demanded taxes and her throne following her husband's death. She gathered a large army from the Iceni and other Celtic tribes and sacked the Roman settlements of Colchester, London, and other towns, killing thousands. However, the Roman army eventually defeated Boudicca's forces in a decisive battle, and rather than be captured, Boudicca took poison and died to avoid living under Roman rule.
