Passage: Throughout the second half of the 18th century, Louisiana was a pawn on the chessboard of European politics. It was controlled by the French, who had a few small settlements along the Mississippi and other main rivers. France ceded the territory to Spain in the secret Treaty of Fontainebleau (1762). Following French defeat in the Seven Years' War, Spain gained control of the territory west of the Mississippi and the British the territory to the east of the river.Following the establishment of the United States, the Americans controlled the area east of the Mississippi and north of New Orleans. The main issue for the Americans was free transit of the Mississippi to the sea.  As the lands were being gradually settled by a few American migrants, many Americans, including Jefferson, assumed that the territory would be acquired "piece by piece."  The risk of another power taking it from a weakened Spain made a "profound reconsideration" of this policy necessary.  New Orleans was already important for shipping agricultural goods to and from the areas of the United States west of the Appalachian Mountains.

Americans used this right to transport products such as flour, tobacco, pork, bacon, lard, feathers, cider, butter, and cheese. The treaty also recognized American rights to navigate the entire Mississippi, which had become vital to the growing trade of the western territories.In 1798, Spain revoked the treaty allowing American use of New Orleans, greatly upsetting Americans. In 1801, Spanish Governor Don Juan Manuel de Salcedo took over from the Marquess of Casa Calvo, and restored the American right to deposit goods. However, in 1800 Spain had ceded the Louisiana territory back to France as part of Napoleon's secret Third Treaty of San Ildefonso. The territory nominally remained under Spanish control, until a transfer of power to France on...
