Cartimandua was the queen of the Brigantes tribe between A.D. 43 and A.D. 69. She helped the Romans suppress the Catuvellauni tribe, another British tribe. She remained loyal to the Romans throughout her reign. In fact, in A.D. 69 the tribe overthrew Cartimandua, and she had to call in the Romans to restore her to the throne. There was a second rebellion as well when the Romans came to her rescue once again, but this time they were only able to save her life and failed to put her back on the throne. By A.D. 74, she had been subdued for good by the Brigantes tribe.
