GUALTERIO, FILIPPO ANTONIO. – Statesman and historian, born in Orvieto on 6 July 1819, died in Rome on 10 February 1874.
Noted for his scholarly publications in history and archaeology, he served as general intendant of the Papal army in the Veneto during the 1848 campaign; and the following year, having refused to adhere to the Roman Republic, he first moved to Florence and then to Turin, where he composed the book *Gli ultimi rivolgimenti italiani* (Florence 1815), which brought him widespread renown. He carried out important missions on behalf of Cavour, played a major role in the Tuscan revolution of 1859 and in the Perugian uprising of the same year, and prepared the annexation of Umbria to the Kingdom of Sardinia. As deputy for Cortona and prefect in several important posts, he served as Minister of the Interior in the Menabrea cabinet in the autumn of 1867, not without assuming significant responsibility for the movement against the Papal State that culminated in the battle of Mentana.
Victor Emmanuel II appointed him Minister of the Royal Household, and in that capacity he advised the sovereign to arrange the marriage of the heir apparent to his cousin Margherita. An outspoken opponent of Rattazzi and disliked by Lanza, upon the formation of the Lanza-Sella ministry he withdrew into private life, working toward a peaceful resolution of the “Roman Question.” Disavowed, he lost his reason and died at the age of fifty-four.
