The Frescobaldi are a prominent Florentine noble family that have been involved in the political, social, and economic history of Tuscany since the Middle Ages. Originating in the Val di Pesa in the Chianti, they appear holding important posts in Florence in the twelfth century. Early history From an early economic base in the Italian community of cloth merchants in Bruges, the Frescobaldi expanded their banking interests to their home city of Florence in the 13th century. Their power base in the city's affairs lay in their participation in the small network that controlled the great cloth-working Arti: the Arte della Lana, the Arte di Calimala, the guild of cloth finishers and merchants in foreign cloth, and the Cambio, or money exchange. In Florence the Frescobaldi found themselves on the wrong side in the attempted power coup of the Grandi in 1343 and were henceforth barred from public service in the Republic, but the Frescobaldi remained prominent in the lesser offices still open to them, such as podestà in the small towns governed from Florence, and through the web of marriage connections among the Florentine ruling class. As bankers, the Frescobaldi financed ventures for numerous members of European royal families, notably their financial conquest of England, which Fernand Braudel has signalled as the greatest achievement of the Florentine firms, "not only in holding the purse-strings of the kings of England, but also in controlling sales of English wool which was vital to continental workshops and in particular to the Arte della Lana of Florence." In the 1270s the Frescobaldi opened an office in London and began financing the wars of King Edward I, eventually supplanting the pioneering Riccardi of Lucca, who were driven to bankruptcy by unpaid loans made to Edward. The Frescobaldi were receivers of the customs of England from 1307, and also served as papal tax gatherers in England, helping to finance the Crusades. With the king's death in 1307, leaving a debt to all creditors that amounted to £30,000 Amedeo de' Frescobaldi continued in the favoured but dangerous position under Edward II; with the fall of Walter Langton, the royal treasurer, at the outset of the new reign, the bishop's debtors, many of them Italians, were instructed to render their debts to Frescobaldi; in 1309 he was granted all the wool customs from Ireland and Scotland.
