Boudica was queen of a Celtic tribe in Britain when the Roman Empire was present there. Her husband kept a stable peace and independence between himself and the Roman Empire. When he died, the Romans ignored his wishes and annexed his lands. Boudica was beaten, and her daughters were abused by Roman soldiers. Afterwards she led a revolt and caused massive havoc for the Roman Empire. She almost caused Rome to leave Britain but that was lost when she was defeated (and killed) with her forces at the Battle of Watling Street
