1. Jefferson wanted to buy the City of New Orleans because O it had a large port so Americans could export goods out of
Spain gave the city and all of Louisiana to the French
Napoleon wanted to set up an empire in Louisiana
all of the above

The Treaty of San Ildefonso was an agreement between France and Spain where Spain gave back the colonial territory of Louisiana to France. It gave the French most of the Missisipi river, and new Orleans, which denied the U.S The Gulf of Mexico. I hope I could help! :D
