Circondario di Viterbo in the province of Rome in the 19 century
The area of the province of Viterbo contained a number of Etruscan cities including Tuscania, Vetralla, Tarquinia, and Viterbo.[6] Viterbo was conquered by the Roman Republic in 310 BCE; despite this, minimal information is known of Viterbo until it was utilised in 773 CE by King of the Lombard Kingdom Desiderius as a base against the Holy Roman Empire. Matilda of Tuscany gifted the city to the papacy in the 11th century. Frederick I, Holy Roman Emperor was based in Viterbo as he planned to invade Rome in 1153, and Frederick I conquered the city in 1160 while preparing to attack Rome.[6]
