The rise of Florence

Conquered by Charlemagne in 774, Florence became part of the duchy of Tuscany, with Lucca as capital. Population began to grow again and commerce prospered. In 854, Florence and Fiesole were united in one county. Margrave Hugo chose Florence as his residency instead of Lucca at about 1000 AD. This initiated the Golden Age of Florentine art. In 1013, construction began on the Basilica di San Miniato al Monte. The exterior of the baptistry was reworked in Romanesque style between 1059 and 1128. Piazza della Repubblica in Florence.Reviving from the 10th century and governed from 1115 by an autonomous commune, the city was plunged into internal strife by the 13th-century struggle between the Ghibellines, supporters of the German emperor, and the pro-Papal Guelphs, who after their victory split in turn into feuding "White" and "Black" factions led respectively by Vieri de Cerchi and Corso Donati. (See Guelphs and Ghibellines.) These struggles eventually led to the exile of the White Guelphs, one of whom was Dante Alighieri. This factional strife was later recorded by Dino Compagni, a White Guelph, in his Chronicles of Florence. Political conflict did not, however, prevent the city's rise to one of the most powerful and prosperous in Europe, assisted by her own strong gold currency, the florin (introduced in 1252), the eclipse of her formerly powerful rival Pisa (defeated by Genoa in 1284 and subjugated by Florence in 1406), and the exercise of power by the mercantile elite following an anti-aristocratic movement, led by Giano della Bella, that resulted in a set of laws called the Ordinances of Justice (1293). Of a population estimated at 80,000 before the Black Death of 1348, about 25,000 are said to have been supported by the city's wool industry: in 1345 Florence was the scene of an attempted strike by wool combers (ciompi), who in 1378 rose up in a brief revolt against oligarchic rule in the Revolt of the Ciompi. After their suppression, Florence came under the sway (1382-1434) of the Albizzi family, bitter rivals of the Medici. Cosimo de' Medici was the first Medici family member to essentially control the city from behind the scenes. Although the city was technically a democracy of sorts, his power came from a vast patronage network along with his alliance to the new immigrants, the gente nuova. The fact that the Medici were bankers to the pope also contributed to their rise. Cosimo was succeeded by his son Piero, who was shortly thereafter succeeded by Cosimo's grandson, Lorenzo in 1469. Lorenzo was a great patron of the arts, commissioning works by Michelangelo, Leonardo da Vinci and Botticelli.
