The terrible pestilence, known as the Black Death, that swept over Europe in 1348, devastated Siena for nearly six months. Even when we remember Boccaccio’s pages, we still read the account in the Cronica Senese with a fresh thrill of horror.[12] It raged from May to October. Men and women felt the fatal swelling, “and suddenly, crying out, they died. The father hardly stayed to see his son; one brother fled the other; the wife abandoned her husband; for it was said that this disease was caught by looking, and in the breath.” So great was the mortality that none could be hired to bury the dead. No sooner was a man’s breath out of his body, than his friends took him to the church and buried him, without any funeral service, as best they could. Huge trenches were dug in different parts of the city, and the dead thrown in, indiscriminately, in great heaps. “And I, Agnolo di Tura called Grasso, buried five of my sons in one trench with my own hands; and many others did the like. And also there were some that were so badly covered up that the dogs dragged them out, and ate many bodies in the city. No bells tolled, and no one wept at any misfortune that befel, for almost every person expected death; and the thing went in such wise that folk thought that no one would remain on live, and many men believed and said: This is the end of the world. Here no physician availed, nor medicine, nor any defence; rather it seemed that the more precaution a man took, the sooner he died.” About three quarters of the inhabitants of city and contado perished, though the “more than 80,000 persons” of Agnolo di Tura must be an exaggeration. While the pestilence raged most fiercely, Bernardo Tolomei and his white robed Olivetani came down from their cloistered retreat to tend the stricken people of their native city, and almost all, including Bernardo, died with them. In the following year the Sienese who survived gave themselves up to feasting and riotous living. They all behaved for a while like brothers and relations, says the chronicler; each one felt as though he had won back the world, and no one could settle down to doing anything. And for a long while Siena seemed uninhabited, per Siena non pareva che fusse persona.

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 next day all Siena was in arms. The Emperor rode through vast acclaiming throngs in the Campo to confer with the Nine in the Palace, while louder and louder rose the deafening roar, “Long live the Emperor and death to the Nine!”—the nobles instigating the populace to further efforts. In the Palace the Caesar received the abdication of the Nine, forced them to renounce all the privileges he had granted them, to annul the oath he had sworn to their ambassadors—while the younger nobles, shouting and cheering, led the populace to sack the palaces of the Provveditori di Biccherna and Consoli di Mercanzia, and the houses of the wool merchants, to release the prisoners, to hunt out the luckless Podestà and War-Captain. 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. A supreme magistracy of twelve popolani was elected, henceforth known as the Signori Dodici, four from each terzo of the city, holding office for two months, one of them to serve as Captain of the People; there was further to be a kind of subsidiary council of six gentiluomini, who were not to reside with the Signoria in the Palazzo, but without whom the Twelve could undertake nothing of importance nor open letters that concerned the state. When the Emperor returned from Rome at the beginning of May and passed through Siena again, he was received with great honours and renewed acclamations, as the Deliverer of the People, and made about sixty knights, nobles of Siena and plebeians alike—many of the latter carried bodily to him on the shoulders of the populace and knighted, amidst the wildest clamour and confusion, against their own will and to the great disgust of the imperial barons.

Hardly had the Emperor left the city than the six nobles—with the consent of their leader, Giovanni di Agnolino Salimbeni, who appears prominently during these years as a powerful influence in the Republic on the side of peace and moderation—were forced to lay down their office. The whole government now remained in the hands of the Twelve, who were mostly petty tradesmen and notaries, and whose rule was corrupt and incapable. A number of the subject towns refused to acknowledge them; Montepulciano gave itself to Perugia, and the Sienese, in revenge, persuaded the governor of Cortona to revolt against the Perugians. A fierce war between Siena and Perugia followed. The Sienese gained a creditable victory outside the walls of Cortona. The light armed cavalry of Perugia harried the Sienese contado, and even approached the gates of the city itself, and the Sienese retaliated by taking the mercenaries of Conrad of Landau into their pay—who were, however, intercepted and severely cut up by the Florentine mountaineers of the Val di Lamone—and ravaged the Perugian territories up to the walls of Perugia. Peace was made at the end of 1358, much to the advantage of Siena, who kept Cortona, while the Perugians had to set Montepulciano free at the end of five years. At the beginning of 1365 the latter town made Messer Giovanni di Agnolino their Podestà, and returned to the obedience of Siena.

During these years of the rule of the Twelve, the contado was perpetually threatened by wandering bands of mercenaries—the Compagnia Bianca, mainly Englishmen, but led by German captains; the Compagnia della Stella; the Compagnia del Cappello of Italians, under Niccolò da Montefeltro; the Compagnia di San Giorgio, which is associated with the great name of John Hawkwood. These had to be compounded with, to be guarded against by enrolling other mercenaries, to be played off against each other. In October 1363, the Sienese, led by their Conservatore or War-Captain, Ceccolo di Giordano Orsini, and stiffened by a strong force of Germans and Hungarians, overtook the Compagnia del Cappello, which was devastating the contado, in the Valdichiana, and gained a complete victory, taking its captain and other leaders prisoners. But when, in March 1367, they tried to play the same game with John Hawkwood and his company of Englishmen, near Montalcinello, there was a very different tale to tell; the Sienese were driven back to Siena in headlong rout, their Conservatore was taken prisoner, and peace had to be purchased at a goodly rate of golden florins. Within the city there was restless plotting against the Twelve, followed by banishments and executions—for this government was by no means so reluctant to lay hands upon the nobles as the Nine had been. Realising that the feeling of the city was turning against them, the Twelve sent a splendid embassy to receive Pope Urban V. when he landed at the Port of Talamone (on his way to Rome in that ineffectual, because premature, attempt to heal the leprosy of Avignon), entered into league with him, sent horsemen under Sozzo Bandinelli and Piero Piccolomini to support the cause of the Church at Viterbo and Bologna. This was good so far as it went, but it did not avert the storm that burst upon Siena in 1368.

The Twelve had split into two factions—the “Canischi” and the “Grasselli.” The Canischi sided with the Tolomei, with whom were Piccolomini, Saracini, and Cerretani; the Grasselli were allied with the Salimbeni. The Emperor was expected in Tuscany, and the most honoured citizen of Siena, Giovanni di Agnolino Salimbeni, had come from Montepulciano to head the embassy that went from Siena to greet Caesar in Lombardy. Although even the magistrates in the Signoria were at daggers drawn, Giovanni’s influence had delayed the catastrophe; but, on his return from the Emperor, he was killed by a fall from his horse on the way from Siena to Rocca d’Orcia. The nobles rose in mass, united with the adherents of the Nine, and senza colpo di spada, at the beginning of September, forced the Twelve to surrender the Palace and the entire control of the State. A new magistracy of thirteen consuls was established; one from each of the five Greater Families, five representatives of the lesser nobles, three to represent the Nine. An embassy was dispatched by this new government to the Emperor; but, in the meanwhile, the Salimbeni had made common cause with the adherents of the Twelve, and sent ambassadors on their own account. On September 24th the Salimbeni, shouting for the People and the Emperor, rushed out of their palace and gardens in arms, joined forces with the Twelve, broke open the Porta di San Prospero, and admitted Malatesta de’ Malatesta, the imperial vicar, who with 800 horse had been lying in wait. From street to street the people and nobles struggled desperately with each other; during the three weeks of their rule, the latter had fortified their houses and enrolled soldiers for this emergency, which enabled them to hold their own at first even against the trained cavalry of the imperial vicar, while their overbearing and tyrannous conduct had exasperated the people to madness. A last stand was made in the Campo round the Palazzo, where there was a grim struggle, grande e aspra battaglia, until Malatesta carried the place by storm, and the populace, rushing in after the imperial soldiery, sacked it. The nobles fled from the city with their families, carrying with them all the goods that they could save from the wreck. Malatesta fortified himself in the Poggio Malavolti, from which, until the following January, he practically ruled the city as imperial vicar; while in the Palazzo a popular council of 124 plebeians met, which was called the Consiglio de Riformatori, and created a new supreme magistracy of twelve, composed of five of the popolo minuto, four of the Twelve, three of the order of the Nine; the Signori Dodici Difensori del Popolo Senese. The same proportion of the three ordini or Monti was to hold in the general council of 650 popolani. To reward the Salimbeni for their services to the People, or, as Malavolti, the aristocratic historian of Siena, puts it, “for the perfidy they had used against the other nobles,” they were given five castles in the Sienese contado and declared popolani, so as to be eligible for the chief magistracy.

The Emperor came back to Siena on October 12th, with the Empress. He entered at the Porta Tufi, where the Twelve and the Salimbeni met him, all crowned with flowers and bearing olive branches. He alighted at the Salimbeni palace, while his followers were quartered in the deserted houses of the exiled nobles. The next day, after Mass in the Duomo, he knighted Reame and Niccolò Salimbeni—“and very little pleasure did any one take in that,” says the Sienese Chronicle grimly. An enormous present of money was made to him and the Empress, as also to Malatesta, and when the Emperor left on the 14th, the Empress remained behind for some days to induce Siena to redeem the imperial crown which had been pawned in Florence. In the meanwhile the nobles were making alarms and excursions in the contado, almost up to the gates of the city. There was another revolution in December. The lowest portion of the populace, or at least lower than those hitherto represented in the administration—“verily plebeians and entirely new men,” as Malavolti has it—assailed the Palazzo, forced their way in, hunted out the representatives of the Twelve and Nine alike. Finally by a sort of general compromise a council of 150 riformatori was appointed, who reformed the State by the creation of a supreme magistracy of Fifteen Defenders, composed of eight of the popolo minuto, four of the Twelve, three of the Nine. This was the origin of the Monte dei Riformatori, because the name was retained in the families of those popolani who took a part in this regime, the names of Nine and Twelve (Nove and Dodici) being retained in those families who belonged to these two orders and shared their fortunes. The Monti of Riformatori, Dodicini, and Noveschi were likewise known as the People of the Greater Number, the People of the Middle Number, and the People of the Lesser Number respectively.[13]

The Emperor rode again into Siena, with the Empress and a long train of knights and nobles, on December 22nd. He dismounted as before at the Palace of the Salimbeni. The nobles were still ravaging the contado and, by means of the Marquis of Montferrat, Charles made some sort of attempt to effect a reconciliation between them and the people, which was cut short by the intrigues of the Salimbeni and Dodicini, who had gained the shallow Caesar’s ear. The arrival of a papal legate, the Cardinal of Bologna, with armed men at the end of the month increased the general alarm: it was rumoured that Charles intended to sell Siena to the Pope. The Emperor demanded the surrender of the fortresses of Massa, Montalcino, Grosseto, Talamone and Casole, and implied that he meant to reform the State; the Fifteen summoned a general council of more than 800 citizens, and returned an absolute refusal. Then the Salimbeni thought that the time had come to strike. On January 18th, Niccolò Salimbeni rode furiously through the street with armed followers, shouting “Long live the People! Down with the traitors who want the nobles back!” Malatesta with his cavalry entered the Campo, drew up in front of the Palace, calling upon the Signoria in the name of Caesar to surrender, and to expel the three representatives of the Nine. Instantly the alarm was sounded from the Mangia Tower. The armed forces of the people poured into the Campo, and their captain, Matteino di Ventura Menzani, with the gonfalone in his hand, led them against the foreign cavalry. The bells were ringing a stormo from churches and palaces, clashing and clanging over the heads of republicans and imperialists, when Caesar himself, his royal helmet crowned with a garland, appeared upon the scenes. With the Salimbeni and a long train of horsemen he was making his way to the Palazzo, when the victorious people, having routed Malatesta, burst upon him at the Croce del Travaglio. The imperial banner was struck down and the imperial forces broken. At the Palazzo Tolomei “there was an incredible battle,” the imperial escort fighting desperately to cover the Caesar’s retreat. One of the Salimbeni, with an olive branch in his hand, came into the Campo in the name of Caesar to implore the Captain to grant a cessation of hostilities, but was promptly sent about his business. By the time that the unfortunate Emperor got back to the Salimbeni Palace, he had lost more than 400 killed—including two of his nephews—and all the hospitals were full of his wounded.

Before the fight had ended the Defenders sent a solemn procession to bring back the three of the Nine who had left the Palace; “with a goodly company, preceded by the trumpets, with garlands on their heads and with olive branches in their hands; they put them back in the Palace in their place, embracing them and kissing them with the greatest tenderness and craving pardon.” The Captain of the People issued a proclamation that no one should sell nor give any food to the Emperor and his folk. “The Emperor remained alone with the greatest fear that any rascal ever had. The people stared at him; he wept and made excuses, embraced and kissed every person that went to him, and said: ‘I have been betrayed by Messer Malatesta and by Messer Giovanni and by the Salimbeni and by the Twelve.’”[14] Half starved and altogether terrified, the unfortunate man promised anything the Sienese wanted, in order to get away from the
