The United States acquired Missouri from France as part of the Louisiana Purchase in 1803, and the territory was admitted as a state following the Missouri Compromise of 1820. Throughout the pre-Civil War period and during the war, Missourians were sharply divided in their opinions about slavery and in their allegiances, supplying both Union and Confederate forces with troops. The state itself, however, remained in the Union.
Missouri historically played a leading role as a gateway to the West, St. Joseph being the eastern starting point of the Pony Express, while the much-traveled Santa Fe and Oregon trails began in Independence.
Missouri’s economy is highly diversified, and service industries provide more income and jobs than any other segment, and include a growing tourism and travel sector. Wholesale and retail trade, manufacturing, and agriculture also play significant roles in the state’s economy.
Missouri is a leading producer of transportation equipment, including automobile manufacturing and auto parts, beer and beverages, and defense and aerospace technology. Food processing is currently the state’s fastest-growing industry.
Missouri mines produce 90 percent of the nation’s principal (non-recycled) lead supply. Other natural resources include iron ore, zinc, barite, limestone, and timber.
