The colony was transferred from French to Spanish control in 1762. The Spanish government actively recruited settlers for Spanish Louisiana. About 2,000 people from the Canary Islands moved to the area south of New Orleans. These settlers were primarily fishermen who soon began supplying large amounts of shrimp, crab, and oysters to the food markets in New Orleans. The Canary Islanders also brought "a love for well-seasoned food", including use of ground cayenne pepper, a spicy hot red chili pepper. Spanish authorities also granted permission for many French-speaking Acadian exiles to relocate from northeastern North America to Louisiana. From 1755 through 1795, almost 3,000 of these settlers, soon known as Cajuns, moved to the areas south and west of New Orleans. Louisiana was secretly returned to France in 1800, then purchased by the United States in 1803. The southernmost part of territorial Louisiana, including New Orleans, became the state of Louisiana in 1812.
