1815 New Orleans Map The city of New Orleans was founded on May 7, 1718, by the French owned Company of the West formerly the Mississippi Company. Named for Philippe d'Orleans, the Duke of Orleans, the city stayed within French control until it was ceded to Spain in 1763. In 1801 the city changed hands again, when the French regained control - though this was short lived. Napoleon sold the Louisiana Territory to the United States in 1803, and New Orleans experienced a population boom shortly thereafter. It is currently the largest city in Louisiana, and is one of the most unique cities in the country. This beautiful map provides a look at the early days of the city. Complete reference list below.
