On the Caribbean island of Curacao, Dutch Jews may have accounted for the resale of at least 15,000 slaves landed by Dutch transatlantic traders, according to Seymour Drescher, a historian at the University of Pittsburgh. At one point, Jews controlled about 17 percent of the Caribbean trade in Dutch colonies, Drescher said.

"Jews were so influential in those colonies that slave auctions scheduled to take place on Jewish holidays often were postponed, according to Marc Lee Raphael, a professor of Judaic studies at the College of William & Mary.

"In the United States, the Jewish role in the slave trade has been a matter of scholarly debate for nearly two decades, prompted in part by efforts to refute the Nation of Islam’s claim that Jews dominated the Atlantic slave trade. But in Holland, the issue of Jewish complicity is rarely discussed.
