Boudīkā

Boudīkā was a priestess of the goddess Andrasta. Queen consort to Prasutagos, she became Queen on his death in 60 AD, when the Romans betrayed their pact with her husband, that they would inherit half of the kingdom of the Iceni and Prasutagos' two daughters the other half. Boudīkā led a revolt, razing three major cities, that nearly drove the Romans out of Britain.

Rebellion
Prasutagos had made a pact with the Romans.
