In the spring of 1544, an Ottoman fleet under Hayreddin Barbarossa sailed into the Bay
of Naples. By the time it left, seven thousand people were gone. Here's how it happened.

Barbarossa had just spent the winter fortified in Toulon, commanding thirty thousand Turkish soldiers on French soil as part of an alliance between the Ottoman Sultan and the King of France. When spring came, he turned that fleet south. He moved through the islands and coastal towns of the Kingdom of Naples, striking one after another. There was no single battle. There didn't need to be one. Coastal villages had almost no way to fight back against a fleet that size. Boats were burned. People were rounded up and marched onto ships before help could arrive from inland. THE NUMBER Seven thousand people: taken from one stretch of coastline, in one campaign, in a matter of weeks.

That number wasn't just a tragedy for the families involved; it broke the slave market itself. Algiers had never seen an arrival like it. Slave traders had a saying for what it looked like when the ships came in: it was raining Christians in the city. Prices collapsed almost overnight. There's a recorded phrase from the time that says it plainly: a person could be traded for a single onion. That wasn't an exaggeration written for effect. It was simply what a human life was worth once seven thousand of them arrived in the same market at once. Most of those seven thousand people don't have names that survived. What survived instead is the saying. Historians still repeat it today, the way it was repeated in Algiers in 1544. "Somewhere, someone paid an onion for a person."
