Third Treaty of San Ildefonso

The Louisiana territory returned to France by Spain makes up almost a third of the United States today

The Third Treaty of San Ildefonso ( Spanish title: Tratado entre España y la República francesa para la cesion del ducado de Parma y retrocesion de la Luisiana ) was a quietly negotiated treaty between France and Spain , in which Spain gave the colony of Louisiana to France returned. The contract was negotiated by Louis Alexandre Berthier , representative of France, and Mariano de Urquijo y Muga , representative of Spain, and signed on October 1, 1800. The treaty was the result of the predicament in which Spain saw itself through Napoléon . The terms of the contract did not exactly set out the boundaries of the territory upon return, which later became a point of contention between Spain and the United States following the Louisiana Purchase of 1803 when France sold its territory to the United States. This treaty confirmed an earlier alliance treaty ( Second Treaty of San Ildefonso ), which had been signed on August 18, 1796 in San Ildefonso.
