Boudica

 was a Celtic queen who ruled a portion of what would become Great Britain — specifically the Iceni kingdom — in the 1st century AD. Unusually, she inherited essentially half the kingdom when her husband, Prasutagas died. The other half was bequeathed to the Roman Empire, thus effectively making the Iceni have two sovereigns:  and the Roman emperor of the day.

When some Romans later raped the Iceni women, 's response was swift and bloody. She ordered that the agents be, according to Seventh Doctor pretending to be John Smith, "skinned alive and impaled on posts with their intestines . . . in their mouths." Since believed these Romans were following orders from the Roman Governor Paulinus, she set the Iceni on a course of general war against the Roman Empire. Ultimately, her rebellion failed, her kingdom was defeated, and she was forced to kill herself.

Nevertheless, she was a heroine of Queen Victoria. (NA: Human Nature)
