During the third quarter of this fourteenth century--the years which still saw the Popes remaining in their Babylonian exile at Avignon--the Florentines gradually regained their lost supremacy over the cities of Tuscany: Colle di Val d'Elsa, San Gemignano, Prato, Pistoia, Volterra, San Miniato dei Tedeschi. They carried on a war with the formidable tyrant of Milan, the Archbishop Giovanni Visconti, whose growing power was a perpetual menace to the liberties of the Tuscan communes. They made good use of the descent of the feeble emperor, Charles IV., into Italy; waged a new war with their old rival, Pisa; and readily accommodated themselves to the baser conditions of warfare that prevailed, now that Italy was the prey of the companies of mercenaries, ready to be hired by whatever prince or republic could afford the largest pay, or to fall upon whatever city seemed most likely to yield the heaviest ransom. Within the State itself the _popolo minuto_ and the Minor Guilds were advancing in power; Florence was now divided into four quarters (San Giovanni, Santa Maria Novella, Santa Croce, Santo Spirito), instead of the old Sesti; and the Signoria was now composed of the Gonfaloniere and _eight_ Priors, two from each quarter (instead of the former six), of whom two belonged to the Minor Arts. These, of course, still held office for only two months. Next came the twelve Buonuomini, who were the counsellors of the Signoria, and held office for three months; and the sixteen Gonfaloniers of the city companies, four from each quarter, holding office for four months. And there were, as before, the two great Councils of the People and the Commune; and still the three great officers who carried out their decrees, the Podestà, the Captain, the Executor of Justice. The feuds of Ricci and Albizzi kept up the inevitable factions, much as the Buondelmonti and Uberti, Cerchi and Donati had done of old; and an iniquitous system of "admonishing" those who were suspected of Ghibelline descent (the _ammoniti_ being excluded from office under heavy penalties) threw much power into the hands of the captains of the Parte Guelfa, whose oppressive conduct earned them deadly hatred. "To such arrogance," says Machiavelli, "did the captains of the Party mount, that they were feared more than the members of the Signoria, and less reverence was paid to the latter than to the former; the palace of the Party was more esteemed than that of the Signoria, so that no ambassador came to Florence without having commissions to the captains."
