With the imperialists ravening like hell-hounds in Rome and Florence in revolt against the Medici, Pope Clement soon had his hands too full of more deadly business to interfere with Siena. But the Sienese returned to their mad factions. Some of the _fuorusciti_ under Giovanni Martinozzi harried the Valdichiana, and Francesco Petrucci made a temporary reappearance upon the scenes, threatening Massa. Within the city the Popolani, led by the Libertini, were attempting to keep down the Noveschi. In July 1527--practically on the anniversary of the great victory of the past year--there was a sanguinary tumult, in which the populace sacked the houses of the leading Noveschi, murdered the younger Pietro Borghesi and a number of others in cold blood. The Monte de' Nove was deprived of any share in the government and annulled, the old Monte de' Riformatori being revived in its stead, and the government was divided between the three Monti--Popolani, Gentiluomini (with Dodicini), Riformatori. Some of the Noveschi were incorporated into the two latter Monti, but the greater part--the Petrucci, Borghesi, Bichi, Placidi, Bellanti, Bulgarini, and the like--was "for ever" admonished and excluded. A number of them were declared rebels and their goods confiscated. Thus permanently ended the supremacy of the Monte de' Nove in the Republic of Siena, the State remaining in the hands of the Popolani and Riformatori. Several of the leaders of the Noveschi were given offices in the Papal States, Aldello Placidi being made Senator of Rome and Fabio Petrucci Governor of Spoleto. Alfonso Piccolomini d'Aragona, Duke of Amalfi, a grand-nephew of Pius III., who was a _persona gratissima_ with the people, was now appointed Captain-General of the forces of the Republic. Siena threw herself into the arms of the Caesarian Majesty of the Emperor and the Catholic Majesty of Spain, combined in the person of Charles V. The Emperor--to whom Siena was the key of Tuscany--sent a garrison of Spanish soldiers, with a series of vicars or governors, beginning with Don Lopez de Soria, who reformed the government again and readmitted the Noveschi, headed by Francesco Petrucci. These, however, no longer held their old position, and were only allowed a fourth part of the Balìa. There were furious tumults again in 1530, when Francesco Petrucci and Giovanni Maria Pini (the hero of the victory at the Porta Camollia) led the Noveschi, and Mario Bandini, as usual, headed the popular opposition, which readily got the upper hand. In one of these Giovanni Martinozzi was killed. An imperial army under the command of the overbearing young Ferrante Gonzaga threatened the city in consequence; Ferrante arrested Mario Bandini, who had come out to confer with him on behalf of the Popolani and Riformatori, but he was unable to reform the government in the favour of the Noveschi. His successor, the popular Marchese del Vasto, succeeded in effecting a compromise.
