Coluccio Salutati (16 February 1331 – 4 May 1406) was an Italian humanist and man of letters, and one of the most important political and cultural leaders of Renaissance Florence; as chancellor of the Republic and its most prominent voice, he was effectively the permanent secretary of state in the generation before the rise of the Medici.
Salutati was born in Stignano, a tiny commune near Buggiano (today's province of Pistoia, Tuscany). After studies in Bologna, where his father lived in exile after a Ghibelline coup in Buggiano, the family returned to Buggiano, which had become more securely part of the Republic of Florence. There he worked as notary and pursued his literary studies, coming into contact with the Florentine humanists Boccaccio and Francesco Nelli. The refined and masterful classical Latin of his letters to Florentine scholars earned him the admiring nickname of "Ape of Cicero", In 1367 Coluccio was appointed chancellor of Todi in the Papal States. Papal secretary Francesco Bruni took Salutati with him to Rome from 1368 to 1370, as assistant in the Papal curia of Pope Urban V recently returned from Avignon. In 1370, through his connections in the curia he was made chancellor of the powerful Tuscan city of Lucca, a post he quickly lost in internecine struggles there.
In 1374 Coluccio received an appointment in Florence and the following year was appointed Chancellor of Florence, the most important position in the bureaucracy of the Florentine Republic. In his position, Salutati was responsible for the widely circulated official correspondences with other states, drafting confidential instructions to ambassadors, conducting diplomacy and negotiating treaties: "in its chancellor Florence had someone truly exceptional, endowed not only with legal knowledge, political cunning and diplomatic skill, but also with psychological penetration, a gift for public relations, and unusual literary skill." His abilities as a statesman were soon tested as Florence was immediately faced with war with the papacy. Salutati was charged with addressing Pope Gregory XI to assure him that Florence was still a loyal member of the Guelf party. Although he failed to prevent war with the papacy, Salutati soon became the most celebrated chancellor in all of Italy and a master of the formal letter. Florence's principal nemesis during his tenure, Giangaleazzo Visconti, Duke of Milan, once remarked that one of Salutati's letters could "cause more damage than a thousand Florentine horsemen." During his life, Florence warred twice against its powerful northern rival, Giangaleazzo Visconti. His treatise De tyranno ("On the tyrant") published in 1400, has, most likely, its model in Visconti, although in it Salutati (despite being a republican) remains a supporter of the providential universal monarch already put forward by Dante. Occasionally his letters had unintended consequences. When he wrote to the people of Ancona in 1376, inciting them, in the name of their freedom, to revolt against the governor imposed by the pope, he called to mind the evils Italy had suffered on behalf of the French. Word of his nasty tone got to the King of France, which prompted a most conciliatory letter from Salutati, assuring the King that he meant no harm and that Florence would always be a friend to France.
