Carolina is the first mass influx. HOPE THIS HELPS YOU!
Carolina was the colony that was populated by the first mass influx of slaves.
Slavery in the colonial area developed from complex factors. Slavery was driven by Europe's American colonies' need for labor, particularly for the labor-intensive plantation economies of the sugar colonies in the Caribbean, operated by Great Britain, France, Spain, and the Dutch Republic.
Most slaves were brought or kidnapped to the Thirteen British colonies.

Slavery in America started in 1619, when a Dutch ship brought 20 African slaves ashore in the British colony of Jamestown, Virginia. Throughout the 17th century, European settlers in North America turned to African slaves as a cheaper, more plentiful labour source than indentured servants, who were mostly poor Europeans.
