who did spain give new orleans and the rest of louisiana to in 1801
Louisiana Purchase A dispute soon arose between Spain and the United States regarding the extent of Louisiana. The territory's boundaries had not been defined in the 1762 Treaty of Fontainebleau that ceded it from France to Spain, nor in the 1801 Third Treaty of San Ildefonso ceding it back to France, nor the 1803 Louisiana Purchase agreement ceding it to the United States.[39]
Treaty of Paris (1763) The Treaty of Paris is frequently noted[by whom?] as the point at which France gave Louisiana to Spain.[citation needed] The transfer, however, occurred with the Treaty of Fontainebleau (1762) but was not publicly announced until 1764. The Treaty of Paris was to give Britain the east side of the Mississippi (including Baton Rouge, Louisiana, which was to be part of the British territory of West Florida). New Orleans on the east side remained in French hands (albeit temporarily). The Mississippi River corridor in what is modern day Louisiana was to be reunited following the Louisiana Purchase in 1803 and the Adams–Onís Treaty in 1819.
