A sufficiently accurate idea of this state of things may be gleaned from the accounts of contemporary witnesses, who were summoned at various times to furnish authentic details as to the condition of the country. Those sent to report upon the monastery of Rosano describe it as being subject to Count Guido, who was continually driven to defend it "against the warden of Montegrossoli, other Teutons, and the Florentine Consuls," all of whom tried to exercise authority there. They also describe how at Monte di Croce, the Consuls of that place and the vice comites all held command simultaneously, and were compelled to defend themselves from the Teutonici, and against the encroachments of the Consuls and other officers of the Florentine Commune.157
On another occasion an equally chaotic state of things is described in the reports on the castle and valley of Paterno, of which Florentines and Siennese disputed the dominion. One witness tells us that in his day he saw a certain Pipino, Potestas Florentiae, holding sway there, and over all the rest of the Florentine contado. Another records how he visited the Paterno valley and the whole of the contado, together with the consuls of the Commune and a Teutonico. Several declare to have gone there now with Pipino, now with other Teutonici, and at other times with the Consuls, and that all received obedience and levied taxes in the same way. Then we have the curious deposition of one Giovanni de Citinaia, who gives a long account of recent events in the district. He tells us how a big pillar was uprooted by a priest, who, not knowing for what purpose it had been planted, wanted to use it for the church he was building. But it was so heavy that even with a cart and two oxen he failed to remove it. And some peasants who were looking on, cried out to him: "Domini sacerdos, male fecisti, quia est terminus inter Florentinos et Senenses" ("Master priest, thou hast done ill, for this is the boundary stone between Florence and Sienna"). After this, the witness continues, two persons went to the warden of Montegrossoli, and said that if he would help them to rebuild the Castle of Paterno, they would furnish him with proofs of his right over it. The warden cheerfully hastened to Florence to get the permission of the authorities, but quickly returned, saying that the building could not go on, for the Florentines refused consent, because the Archbishop Christian of Mayence was already in Lombardy on the way to Tuscany. Thereupon the Siennese made use of the favourable opportunity to demolish the neglected works, and play the masters themselves. It is certainly impossible to conceive a greater multiplicity and confusion of contrasting rights and authorities.158
Hence the only course open to Florence and the Tuscan communes in general was to seize every convenient occasion of asserting their rights either by craft or by violence. The war between Pisa and Lucca had already broken out, and as Count Guido, the foe of the Florentines, had joined with Lucca, they formed an alliance with Pisa. This treaty was very advantageous to their commerce, but it pledged them to an active share in the war.159 They willingly undertook this, for it was an opportunity of fighting not only the Lucchese, but also the latter's patrons, Count Guido and Christian of Mayence. At first it seemed as though Pisa would be forced to make peace, for on March 23, 1173, Christian declared that city to be under ban of the Empire, thus stripping it of all the privileges it had previously enjoyed. In fact, on the 23rd of May an agreement was concluded (witnessed also by the Florentines) to the effect that Pisa and Lucca should proceed to an exchange of prisoners. The ban was raised on the 28th of the same month, and peace was solemnly proclaimed in Pisa on the 1st of June.
But two months afterwards an unexpected event caused the war to be speedily renewed. The archbishop had invited the Consuls of Pisa and Florence to come to San Genesio on the 4th of August, and on their arrival had them promptly seized and cast into prison. What could have caused an act rendering war unavoidable, after such strenuous efforts to establish peace? Many explanations have been suggested, but one fact alone is well ascertained. Certain men of San Miniato, having been expelled as rebels to the Empire, had sought the Bishop of Florence160 in his palace, and sworn not only to make common cause with the Pisans and Florentines, but to cede them the territory of San Miniato, should they succeed in retaking it, and even if the fortress remained in the hands of the Germans.161 This is certainly true, for the document containing the agreement is still extant. It is no regular treaty, being unwitnessed by Consuls, and lacking the proper legal formulas. But the fact of its having been sworn to and signed in the bishop's palace; of some leading citizens, including one of the Uberti,162 having been parties to it; and of the document being preserved in the Archives,163 proves that the rulers of the two cities were not unaware of the agreement, but merely preferred to hide, or rather disguise the real importance of it. All this, joined to their reluctance and delay as to the exchange of prisoners, persuaded Christian that they were trying to trick and betray him by a fictitious peace. Accordingly, his patience being exhausted, he was led to commit an imprudent and ill-considered action, that destroyed all hope of the peace he was so anxious to conclude.
In fact, by August the Florentines were already at Castel Fiorentino, and, reinforced by a contingent of 225 horse, accompanied by two Consuls from Pisa, encamped at Pontedera. Christian quickly marched against them, together with Guido and the Lucchese, but the latter were obliged to forsake him, for the Pisans, by advice of the Florentines, had entered the Lucca territory and were laying it waste. Notwithstanding his diminished force he attacked the enemy, and valiantly defended his banner, but was worsted in the fight. How the war went on is unknown to us; but it is certain that Christian soon took his departure, that in 1174 the rebels of San Miniato returned with honour to their native town, and that finally in the following year peace was concluded between the three hostile cities.164
Meanwhile the Florentines continued to subject the towns and castles of the territory to their rule.165 Before this, in 1170, they had wrung hard conditions from the Aretines,166 who were friendly to Count Guido, and they now marched against Asciano, a walled town near Arezzo, partly under their rule and partly under that of the Siennese, who were now trying to get full possession of it. The latter were routed on July 7, 1174, and leaving a thousand prisoners in the enemy's hands were accordingly obliged to submit to very disadvantageous terms.167 The negotiations were carried on slowly, but peace was concluded at last in 1176.
The Florentines were acknowledged as the legitimate masters of the whole contado of Fiesole and Florence, and obtained part of the Siennese possessions at Poggibonsi, the said Siennese being bound to help them in all wars,168 save against the emperor or his envoys, and likewise pledged to use every endeavour to conciliate the latter in favour of Florence. Several more of the conditions were particularly harsh.169 That the Florentines could extort such terms as these after the petty war of Asciano is an undeniable proof of their increased power; but it is equally certain that unless the Siennese were hopelessly ruined, this was only a fictitious peace, concluded after great hesitation, and for the sole purpose of securing the release of the prisoners.
III.
Nevertheless, these triumphs abroad were counteracted by unforeseen events in Florence itself. Owing to the prevalence of the popular party in the consular government, powerful houses in general, and the Uberti faction in particular, were increasingly excluded from public affairs, and naturally showed signs of discontent. At this moment we seldom find any of their names at the head of the Commune.170 Meanwhile, however, many neighbouring castles and lands having been reduced to submission, the number of nobles of the contado dwelling in the city had been greatly augmented. These, being merely counted as assidui habitatores or cives salvatichi, could have no share in the government, but there was nothing to prevent them from joining the disaffected party and swelling its numbers and strength. And when, in course of time, they became full citizens, their power of action was enlarged. Accordingly, at last, in 1177, the Uberti were encouraged to hazard the revolution that first initiated civil war in Florence.
