Prasutagus was a first-century ruler of the Iceni in eastern Britain who maintained a client relationship with Rome. He is known principally from Tacitus, who describes him as wealthy and as the husband of Boudica.
According to Tacitus, Prasutagus attempted to protect his dynasty by naming both the Roman emperor and his daughters as heirs. After his death Roman officials seized property and abused his family, actions that helped trigger the great Iceni-led revolt under Boudica in AD 60 or 61.
In Marion Zimmer Bradley’s Ravens of Avalon, before the Roman conquest hardens into occupation, young Boudica studies on Mona and befriends the priestess Lhiannon. Called home to marry Prasutagus, king of the Iceni, Boudica attempts to preserve her family’s position under Roman rule while Lhiannon and the Druids resist the destruction of their sanctuaries. In K. M. Ashman’s The Wrath of Boudicca, in AD 60 the death of Prasutagus leaves the Iceni exposed to Roman confiscation and abuse. Boudica answers the treatment of her family by uniting discontented communities and leading an uprising against the province. Prasutagus is treated fictionally in Rosemary Sutcliff’s Song for a Dark Queen.
