Boudica or Boudicca was a queen of the British Iceni tribe who led an uprising against the conquering forces of the Roman Empire in AD 60 or 61. According to Roman sources, shortly after the uprising failed, she poisoned herself or died of her wounds, although there is no actual evidence of her fate. She is considered a British folk hero.

In AD 60 or 61, when the Roman governor Gaius Suetonius Paulinus was campaigning on the island of Mona (modern Anglesey) on the northwest coast of Wales, Boudica led the Iceni, the Trinovantes, and others in revolt. They destroyed Camulodunum (modern Colchester), earlier the capital of the Trinovantes but at that time a colonia, a settlement for discharged Roman soldiers and site of a temple to the former Emperor Claudius.

Upon hearing of the revolt, Suetonius hurried to Londinium (modern London), the 20-year-old commercial settlement that was the rebels' next target. He lacked sufficient numbers to defend the settlement, and he evacuated and abandoned Londinium. Boudica led a very large army of Iceni, Trinovantes, and others against a detachment of the Legio IX Hispana, defeating them, and burning Londinium and Verulamium (a town southwest of the modern city of St Albans).
