Why was queen boudica angry at the Romans?

Queen Boudica was angry at the Romans due to their harsh treatment of her people, the Iceni tribe, after her husband's death. The Romans annexed Iceni lands, imposed heavy taxes, and publicly humiliated Boudica and her daughters. This mistreatment ignited her rebellion against Roman rule, leading to a significant uprising in AD 60-61. Boudica's anger was fueled by both personal loss and the broader oppression faced by her people.
