''Florence originated as a Roman city, and later, after a period as a flourishing trading and banking medieval commune, it was the birthplace of the Italian Renaissance (or the "Florentine Renaissance"). According to the Encyclopædia Britannica, it was politically, economically, and culturally one of the most important cities in Europe and the world from the 14th century to the 16th century.
The language spoken in the city there during the 14th century was, and still is, accepted as a pan-Italian language. Almost all the writers and poets in the Italian literature of thegolden age are somewhat connected with Florence, leading ultimately to the adoption of the Florentine dialect above all the local dialects, as a literary language of choice.
Starting from the late Middle Ages, Florentine money – in the form of the gold florin – financed the development of industry all over Europe, from Britain to Bruges, to Lyon and Hungary. Florentine bankers financed the English kings during the Hundred Years War, as well as the papacy, including the construction of their provisional capital ofAvignon and, after their return to Rome, the reconstruction and Renaissance embellishment of the latter.
Florence was home to the Medici, one of history's most important noble families.Lorenzo de' Medici was considered a political and cultural mastermind of Italy in the late 15th century. Two members of the family, were popes as Leo X and Clement VII in the early 16th century. Catherine de Medici, married king Henry II of France and, after his death in 1559, reigned as regent in France. The Medici reigned Grand Dukes of Tuscanystarting with Cosimo I de' Medici in 1569, until the death of Gian Gastone de' Medici in 1737.''
