During the Civil War, Louisiana joined the Confederacy, but New Orleans was captured by Union Adm. David Farragut in April 1862. The state's economy suffered during Reconstruction; however, the situation improved at the turn of the 20th century, with the discovery of oil and natural gas and the growth of industry.
A low country on the Gulf coastal plain and the Mississippi alluvial plain, Louisiana rises in uplands near Arkansas only to some 535 ft (163 m). The rainy coast country contains marshes and fertile delta lands; inland are rolling pine hills and prairies.
The state's principal agricultural outputs include seafood, cotton, soybeans, cattle, sugarcane, poultry and eggs, dairy products, and rice. Its industrial outputs include chemical products, petroleum and coal products, food processing, transportation equipment, paper products, and tourism.
Other major points of interest include the Superdome in New Orleans, historic plantation homes near Natchitoches and New Iberia, Cajun country in the Mississippi Delta Region, Chalmette National Historic Park, and the state capital at Baton Rouge.
