Boudica, Celtic warrior queen.
"In stature she was very tall, in appearance most terrifying, in the glance of her eye most fierce, and her voice was harsh," Roman historian Dio Cassius wrote of Iceni Queen Boudica. Suetonius Paulinus, Roman Governor of Britain, who led the final attack against Boudica's forces called her a "treacherous lioness." Today, Boudica is revered as a symbol of British independence.
After her husband's death, the occupying Roman forces stripped the Iceni of autonomy and publicly raped Boudica's two daughters while she was forced to watch. Then in AD 60, Boudica rallied a force of 20,000 Celtic tribesmen and revolted. Led by the warrior queen, the rebels razed three cities, including the Rome's capital in Britain located in present-day London, killing an estimated 70,000 soldiers and civilians in the process. Roman Governor Suetonius Paulinus overthrew the Boudica's army, after which point Boudica is thought to have poisoned herself.
