The Zorg is the most consequential slave ship of the 18th century whose voyage changed the course of history, yet the story remains largely unknown.

Drawing on a trove of archival materials, New York Times bestselling author Siddharth Kara uncovers new details of the Zorg's voyage and takes the reader on a gripping journey from the Netherlands to Africa’s Gold Coast where it was captured by a British privateer before loading its human cargo and heading onto Jamaica on its ill-fated journey to fuel the lucrative sugar trade.

A series of unpredictable weather events and mistakes in navigation left the ship drastically off course, running out of food and water. To save the crew and the most valuable of the slaves, the captain decided to throw 140 slaves, mostly women and children, overboard.

What followed is a fascinating legal drama in England’s highest court that turned the brutal business of slavery into front page news. For the first time, concepts such as human rights and morality entered the discourse on slavery, in a notorious case that boiled down to a simple but profound question: were the Africans on board the Zorg people or cargo?

The case of the Zorg catapulted the nascent anti-slavery movement to one of the most consequential moral campaigns that changed the course of history.
