The Medici Bank — the family that invented modern banking
From money changers in Florence, the Medici built Europe's most powerful bank and produced three popes and two queens. How did they do it?
In the 15th century, the Medici family of Florence turned a small currency-exchange business into Europe's largest bank. They had branches from Rome to London and managed the money of the Pope himself.
The invention that changed everything
The Medici perfected the bill of exchange — a kind of international check. A merchant deposited florins in Florence and collected the equivalent in another currency in London, without carrying gold along robber-filled roads. They also pioneered double-entry bookkeeping, the basis of every bank today.
Money and power
With their amassed fortune, the Medici funded artists, ruled Florence and produced popes and queens. It is history's clearest proof that whoever controls money controls much else — and why understanding how a bank works is a power in itself.
The Medici conquered not with the sword, but with the ledger. Knowledge of money was their weapon.
