Debt: The First 5,000 Years

by David Graeber

The Venetians were only the most famous in this regard. They created a veritable mercantile empire over the course of the eleventh century, seizing islands like Crete and Cyprus and establishing sugar plantations that eventually—anticipating a pattern eventually to become all too familiar in the New World—came to be staffed largely by African slaves.133 Genoa soon followed suit; one of their most lucrative businesses was raiding and trading along the Black Sea to acquire slaves to sell to the Mamluks in Egypt or to work mines leased from the Turks.134 The Genoese republic was also the inventor of a unique mode of military financing, which might be known as war by subscription, whereby those planning expeditions sold shares to investors in exchange for the rights to an equivalent percentage of the spoils. It was precisely the same galleys, with the same “merchant adventurers” aboard, who would eventually pass through the pillars of Hercules to follow the Atlantic coast to Flanders or the Champagne fairs, carrying cargoes of nutmeg or cayenne, silks and woolen goods—along with the inevitable bills of exchange.
