On November 29, 1781, the crew of a British slave ship called The Zong, murdered over one hundred African slaves that were bound for Jamaica. The crew threw the 133 slaves overboard so that they could claim insurance for the “lost cargo”. The Zong’s first mate refused to participate in the massacre and he later testified against the crew at trial. Following the Zong affair there was a strong public outcry. The public’s reaction to this genocide helped to hasten the United Kingdom’s eventual prohibition of slavery.
