A Vengeance Stirred by Roman Atrocity
Boudica’s husband Prasutagus had in his lifetime reached an agreement with Rome, seeking to preserve the tribe’s autonomy by bequeathing part of his property to the Roman emperor, but after his death the Roman authorities tore up the agreement, not only confiscating all the tribe’s land and property but publicly flogging Boudica herself and letting the soldiers abuse her two daughters — this series of atrocities became the direct spark igniting the large-scale revolt of the British tribes Boudica led against Roman rule.
The Burning of Three Roman Strongholds
Boudica led the allied rebel army to take in turn three important Roman strongholds in Britain: Colchester (then the provincial capital), Londinium (present-day London), and Verulamium, and the rebels carried out an exceedingly savage retaliatory slaughter of Roman civilians and locals who supported Roman rule, the death toll reaching seventy to eighty thousand by Roman sources, and the layer of clear burn marks, the "Boudican destruction layer," excavated by archaeologists beneath London is still direct material evidence of this devastating revolt.
