Louisiana
  

No other state has a more varied or colorful past than Louisiana. The state has been governed under 10 different flags beginning in 1541 with Hernando de Soto's claim of the region for Spain. La Salle later claimed it for Bourbon France and over the years Louisiana was at one time or another subject to the Union Jack of Great Britain, the Tricolor of Napoleon, the Lone Star flag of the Republic of West Florida and the fifteen stars and stripes of the United States. At the outbreak of the Civil War, Louisiana became an independent republic for six weeks before joining the Confederacy.

Earlier, in 1803, Louisiana had become a part of the United States because of the region's importance to the trade and security of the American mid-west. New Orleans and the surrounding territory controlled the mouth of the Mississippi River down which much of the produce of the mid-west traveled to reach market. To get the vital region in American hands, President Thomas Jefferson negotiated the Louisiana Purchase with Napoleon.

With the acquisition of Louisiana, Jefferson nearly doubled the size of the fledgling U.S. and made it a world power. Later, 13 states or parts of states were carved out of the Louisiana Purchase territory.

Through much of its early history Louisiana was a trading and financial center, and the fertility of its land made it one of the richest regions in America as first indigo then sugar and cotton rose to prominence in world markets. Many Louisiana planters were among the wealthiest men in America.

The plantation economy was shattered by the Civil War although the state continued to be a powerful agricultural region. The discovery of sulphur in 1869 and oil in 1901, coupled with the rise of forestry sent the state on a new wave of economic growth. Eventually, Louisiana became a major American producer of oil and natural gas and a center of petroleum refining and petrochemicals manufacturing, which it remains to this day.
