 In 1749, the city of Port-au-Prince was established on the West coast, which in 1770 took over as the capital of the colony from Cap-Français, however that same year the 1770 Port-au-Prince earthquake and tsunami destroyed the city killing 200 people immediately, and 30,000 later from famine and disease brought on by the natural disaster.This was the second major earthquake to hit Saint-Domingue as it followed the 1751 Port-au-Prince earthquake which had left only a single stone built building standing in the town.Prior to the Seven Years' War (1756–63), the economy of Saint-Domingue gradually expanded, with sugar and, later, coffee becoming important export crops.
