History

1718- Jean Baptist Le Moyne, “Bienville,” founded New Orleans along the Mississippi River. This trade-friendly location later became the capitol of the French colony of Louisiana and shaped the future of the United States.

1762- France gives Louisiana to Spain.

1795-98 Spain signed a three year treaty granting Americans the right to freely navigate the Mississippi River and the right to deposit goods in the Port of New Orleans. After the treaty expired, Spain refused to allow American vessels to enter the Port of New Orleans.

1798- Americans in the Ohio Basin claimed they couldn’t survive without the use of the Mississippi River. President Thomas Jefferson suggests purchasing New Orleans from Spain, which had secretly given Louisiana back to France.

1803- The U.S. buys the entire colony of Louisiana from France for $15 million. The Louisiana Purchase doubled the U.S. in size, all due to the need for the Port of New Orleans.

1862- One year after the American Civil War began, Union forces captured New Orleans and closed the port to the Confederate Army, cutting off a main source of supplies and money.
