Haiti had historically occupied what is now the Dominican Republic from 1822 to 1844. Encroachment by Haiti was an ongoing process, and when Trujillo took over, specifically the northwestern border region had become increasingly "Haitianized." The border was poorly defined. In 1933, and again in 1935, Trujillo met the Haitian President Sténio Vincent to settle the border issue. By 1936, they reached and signed a settlement. At the same time, Trujillo plotted against the Haitian government by linking up with General Calixte, Commander of the Garde d'Haiti, and Élie Lescot, at that time the Haitian ambassador in Ciudad Trujillo (Santo Domingo). After the settlement, when further border incursions occurred, Trujillo initiated the Parsley Massacre.
