The order of the Nine fell in 1355, and thirteen years of tumultuous, perpetual change followed. The Emperor elect, Charles IV.--"di Lusimburgo ignominioso Carlo," as Fazio degli Uberti calls him--was on his way from Pisa to be crowned at Rome; the Sienese ambassadors, headed by Guccio Tolomei and Giovanni di Agnolino Salimbeni, had sworn fidelity to him at Pisa on behalf of the Nine, and he had sworn in return to preserve the liberties of Siena, and to make the Nine his vicars. With a thousand knights and barons, the Emperor and Empress entered Siena on March 25th, each under a baldacchino gorgeous with gold, with music playing and banners flying, and were greeted with enthusiasm. No sooner had the Caesar dismounted at the palace of the Salimbeni, than a cry arose throughout the city: "Long live the Emperor and death to the Nine!" The Piccolomini with the consent of the other magnates (excepting only Giovanni di Agnolino Salimbeni) began the rising, and the _popolo minuto_ on the following day rose in arms at their call. When night fell, on the 26th, the chains of the city were cut, and the keys brought to the Emperor; the Nine, helpless and terrified, lurked in the Palace of the Commune, while the people sacked and burned their houses.

The books of condemnation, the papers of the Nine, were burnt before the Emperor's eyes in the piazza, and their official chest was dragged through the city at the tail of an ass. Though Charles had sufficient decency to refuse to surrender the persons of the Nine to the fury of the mob outside, he let the nobles and populace avenge themselves on their houses and property, and it was not until the evening had come that he sent his soldiers to guard the Dogana del Sale, and to order every one to lay down their arms. But such was the general alarm that no one would receive any of the adherents of the luckless Nine; their servants deserted them, the very priests and religious shrank from them as though they had the plague. The Emperor caused a certain number of citizens to be elected--twelve nobles and eighteen of the _popolo minuto_ to "reform the government," and went on his way leaving his vicar, the Patriarch of Aquileia, in charge.
