Read the passage and study the map from Sugar Changed the World . When the Haitians defeated the French armies, Napoleon lost control of the world's most productive sugar islands and with it his dream of great sugar profits. As a result, Napoleon had no use for the land in North America he had so recently obtained from Spain. Napoleon did, though, need money to pay for his wars. That is why he sold the vast Louisiana Territory to Jefferson for the bargain price of just fifteen million dollars. What textbooks call the Louisiana Purchase should really be named the Sugar Purchase. Americans obtained the middle part of what would become their nation because the Haitians achieved their freedom. But, paradoxically, that gave Haitian slave owners a new home. As sugar planters fled from the revolution in Haiti, some moved to Cuba's Oriente Province, others to North America—to Louisiana. How does the map help develop the central idea that the Louisiana Purchase had profound effects on sugar and the United States?
