The roots of modern capitalism go back to the Italian banking system of the late Middle Ages and the Renaissance. In the fifteenth century, the Medici Bank succeeded in overshadowing its competitors, the Bardi and the Peruzzi, who were the giants of the fourteenth century, and grew into a vast establishment with branches in most of the large cities of Western Europe. A study of its operations is essential to an understanding of the economic conditions in Europe in the fifteenth century. From a careful study of pertinent documents, including a set of libri segreti (confidential ledgers) discovered in 1950, Professor de Roover has reconstructed the details of the bank's organization and operating methods; its loan policies, which reflected the Church's doctrine on usury; its trading and industrial investments; its roles within the Florentine gild system and tax structure; and its activities as financial agent of the Church. He covers every aspect of the bank's history, from its early years under the management of Giovanni di Bicci de' Medici to its collapse with the expulsion of the Medici from Florence.
« The Medici name exerted goodwill from its customers » explains the rise of the bank from having a great reputation so much so that all princes and nobles wanted to do business with the bank. This would explain why despite being smaller than other notable banks such as the Bardi bank they had higher profits. But like Cosimo’s advice on his deathbed for the family to take modest dress in public, his advice of not lending to princes was under our suspicion to be also taken with a grain of salt, such as one would when reading French. As this ended up being the downfall of the bank where Lorenzo was not able to keep track of balance sheets to the point he could surreptitiously decipher when one of his branch managers was lending to a prince. Perhaps like the advice on modest dress the best way to approach this was by focusing on the princes accounts and having negotiators to keep track of their current tab. Extravagant spending nailed the final coffin on the bank with Lorenzo’s son who was pope.
This is a great description of the origins of commerce and banking as we know them. The Medici Bank was headquartered in Florence, Italy, and had branches all over Europe. It has interesting implications for banking centralization and decentralization and I used it as required reading when I used to take student groups to Italy. It is well-referenced and fairly readable for those of us interested in the topic.
A comprehensive narrative and economic analysis of the Medici Bank. de Roover is second to none in his approach to economic history and presents a wealth of data to support his argument.
