False. Boudicca, also known as Boadicea, was a Celtic tribal queen who led a major uprising against the Roman Empire in Britain. She did not fight the Vikings as they were a different historical group that arrived in the British Isles several centuries after Boudicca's time. Boudicca's rebellion occurred in AD 60 or 61, primarily targeting Roman forces and settlements in the province of Britannia. The Viking Age, characterized by Viking raids and invasions, began in the late 8th century AD, several centuries after Boudicca's uprising.
