I am currently, ambitiously, slooooowly reading a history of the Roman invasion of Britain in The Story of Britain by Rebecca Fraser. Yesterday, it was Caratacus, who avenged his land, got caught, asked to be freed, was freed, end of story. But today is about Queen Boudica.
Queen Boudica was the wife of Prasutagus, ruler of the Iceni tribe. In Prasutagus' will, he wanted his land to be left jointly to his two daughters and the Roman Emperor. Following his death, the empire ignored his wishes and the Queen was flogged and his daughters were raped.
Boudica was pissed and led the Icenis and neighboring tribes on a roaring rampage of revenge in 60 A.D. They destroyed three cities, including Londinium (London) and killed supposedly 70-80,000 people.
She was finally defeated at the Battle of Watling Street due to poor planning and an ineffective use of the land. Her rampage was enough for Emperor Nero to debate on whether to withdraw Roman forces from Britain entirely. Unfortunately, her loss ended up marking the end of resistance to Roman rule in the southern half of the island until 410 A.D.
Queen Boudica and her daughters, wanting to avoid their inevitable fate, drank poison rather than be captured.
