What caused Boudicca’s rebellion against Roman rule?
Boudicca’s rebellion in 60–61 CE was primarily triggered by the Roman Empire’s failure to honor the will of her husband, Prasutagus, the king of the Iceni tribe.12
Prasutagus had ruled as a client king under Roman suzerainty and, upon his death, left his kingdom and private wealth to his two daughters and the Roman emperor Nero in an attempt to secure protection for his family. Instead of honoring these terms, Roman authorities annexed the kingdom, plundered the assets of the chief tribesmen, and committed severe atrocities against the royal family, including the flogging of Boudicca and the rape of her daughters.13
These acts of humiliation and violence, combined with the broader Roman policy of seizing tribal lands, prompted Boudicca to lead a massive uprising of the Iceni and the allied Trinovantes tribe against Roman rule in East Anglia.123
