The Medici summary

At the height of their power, the Medici would recount the tale of their noble origins, claiming descent from a legendary knight called Averardo who fought for Charlemagne way back in the eighth century. According to family mythology, Averardo slayed a giant while passing through Mugello, which explained their origins in the region. 

But the reality was far more ordinary. In the 1200s, the Medici were small farmers working land along the river Sieve in the hills about twenty five miles northeast of Florence. In the small town of Cafaggiolo, they were peasants, not knights, and part of the vast agricultural backbone of medieval Italy. 

Italy at this time was not a unified nation but a patchwork of competing city-states, each fiercely protective of its trade routes and political independence. Florence, Venice, Genoa, and Milan jostled for dominance while smaller cities like Lucca and Siena fought to maintain autonomy. The Pope wielded enormous temporal power from Rome, and foreign empires circled like wolves, eyeing Italy's wealth.

Florence in the 1300s was far from the most powerful Italian city. Venice controlled Mediterranean trade routes, Milan boasted military might, and Rome held spiritual authority. But Florence discovered something more valuable than armies or ports. It figured out how to create wealth through textile production and financial innovation. 

Florentine wool guilds mastered the art of transforming raw English fleece into luxury cloth that commanded extraordinary prices across Europe and the Levant. This economic engine would eventually fund a cultural explosion that transformed Western civilization.

Sometime in the early 1300s, the Medici abandoned farming and migrated to Florence, arriving as this commercial energy was being built. Wool and silk guilds controlled the economy, and merchant families competed ruthlessly for market share. Florence operated as a republic in name, governed by guild representatives rather than kings or emperors, but real power belonged to whoever controlled the money. 

The Medici started small, running a modest money-changing operation. In an era before standardized currency, travelers needed to exchange the coins of dozens of different cities and kingdoms. A sharp eye for metal content and exchange rates could yield steady profits.

By the mid-1300s, Vieri di Cambio de' Medici had transformed this humble business into something more substantial. Vieri understood that real wealth came not from exchanging coins but from lending money at interest. The Catholic Church officially condemned usury, citing biblical prohibitions against profiting from loans. But clever bankers developed theological arguments to navigate this restriction. 

They reasoned that interest compensated not for the loan itself but for the risk of loss and the opportunity cost of capital deployed elsewhere. They disguised charges as fees for currency exchange or penalties for late payment. These intellectual gymnastics satisfied enough clerics to allow banking to flourish.
