Queen Boudicca was married to Prasutagus ruler of the Iceni of East Anglia. When the Romans conquered southern England in AD 43, they allowed Prasutagus to continue to rule. However, when Prasutagus died the Romans decided to ignore his will, which left his kingdom shared between his daughters and the Romans, and to rule the Iceni directly. They confiscated his property and are also said to have stripped and flogged Boudicca and raped her daughters. These actions exacerbated widespread resentment at Roman rule.
In 60 AD, while the Roman governor Gaius Suetonius Paullinus was on campaign in North Wales, the Iceni led by Boudicca, rebelled and were joined by other tribes. In response the Ninth Legion based at Longthorpe Fortress and led by Quintus Petillius Cerialis marched to meet her army, but they were defeated and she went on to destroy Camulodunum (Colchester) the capital of Roman Britain.
Boudicca's warriors then destroyed London and Verulamium (St Albans) killing thousands. Suetonius marched back from Wales and finally defeated her. She is thought to have poisoned herself to avoid capture. The site of the battle, and of Boudicca's death, are unknown.
