Why did Queen Boudicca lead a revolt against Roman rule in Britain?

Queen Boudicca led a revolt against Roman rule in 60–61 CE primarily due to the brutal treatment of her family and the violation of her late husband’s will.12

Her husband, Prasutagus, was the king of the Iceni and a client ruler under the Roman Empire. Upon his death, he left his private wealth to his two daughters and the emperor Nero, hoping to secure imperial protection for his family. Instead, Roman authorities ignored the will, annexed his kingdom, and plundered the property of the chief tribesmen. In a display of extreme cruelty, the Romans flogged Boudicca and raped her two daughters.23

These acts of violence and the systematic humiliation of her family drove Boudicca to lead the Iceni and allied tribes, such as the Trinovantes, in a widespread rebellion against Roman occupation. While the Roman governor Suetonius was away, the insurgents destroyed several major Roman centers, including Camulodunum, Verulamium, and London, before being ultimately defeated at the Battle of Watling Street.23
