What medieval city was famously a center for banking in Italy?

The story behind the answer

Florence’s great merchant-banking houses—Bardi, Peruzzi, Strozzi, and later the Medici—dominated European finance from the 1200s to the 1400s. They moved money for the papacy, financed kings, and spread the use of bills of exchange that let merchants settle accounts across borders without hauling coin. Its gold florin, first minted in 1252, became a trusted reference currency for international trade.

Banking wealth reshaped the city: families turned financial power into political control and artistic patronage, funding works by Brunelleschi and Botticelli. Earlier crashes—like Edward III’s default in the 1340s—show the reach and risk of Florentine credit networks. While Venice and Genoa ruled the seas, Florence’s looms and ledgers made it Europe’s financial nerve center in the late Middle Ages.
