In 1665, the presence of French people on the island had the official approval of the French king Louis XIV and he named Bertrand d'Ogeron as the governor of the western part of Hispaniola (in French, Saint-Domingue). By the Treaty of Ryswick, Spain gave the western third of the island to France and kept the eastern part. The development of the French "Saint-Domingue" was very fast, both in wealth and population, and it became the richest colony in the Caribbean. The eastern, Spanish colony of "Santo Domingo" remained poor and with a very low population.
