 After US forces left in 1934, Dominican dictator Rafael Trujillo used anti-Haitian sentiment as a nationalist tool.In an event that became known as the Parsley Massacre, he ordered his army to kill Haitians living on the Dominican side of the border.Few bullets were used – instead, 20,000–30,000 Haitians were bludgeoned and bayonetted, then herded into the sea, where sharks finished what Trujillo had begun.
