The historian Marcus Rediker opens “The Slave Ship: A Human History” with a harrowing reconstruction of the journey, for a captive, from shore to ship:

An estimated 12.5 million people endured some version of this journey, captured and shipped mainly from the western coast of Africa to the Western Hemisphere during the four centuries of the trans-Atlantic slave trade. Of that number, about 10.7 million survived to reach the shores of the so-called New World.

It is thanks to decades of painstaking, difficult work that we know a great deal about the scale of human trafficking across the Atlantic Ocean and about the people aboard each ship. Much of that research is available to the public in the form of the SlaveVoyages database. A detailed repository of information on individual ships, individual voyages and even individual people, it is a groundbreaking tool for scholars of slavery, the slave trade and the Atlantic world. And it continues to grow. Last year, the team behind SlaveVoyages introduced a new data set with information on the domestic slave trade within the United States, titled “Oceans of Kinfolk.”
