 In 1592 Gianfrancesco Monaldeschi was found guilty of harbouring brigands and rebels against Papal power, and Pope Clement VIII confiscated in favour of the Papal treasury, half of the Monaldeschi holdings in Trevinano, selling three-quarters of the remainder to Giacomo Cardinal Simoncelli, bishop of Orvieto, 26 June 1598.With the cession to the Papal States of Torre Alfina in 1664, the Monaldeschi ceased to play a part in the politics of Central Italy, though the marchese Gian Rinaldo Monaldeschi was reputed to be the lover of Christina of Sweden in her Roman retirement.When she discovered that Monaldeschi had betrayed her plans to take the Kingdom of Naples to the Pope, she had him assassinated 10 November 1657, in her presence at Fontainebleau, where the queen was staying in her passage through France.
