Answer:
Spain received Louisiana as a result of France’s defeat in the French and Indian War.
Step-by-step explanation:
With the French defeat in the French and Indian War in 1763 the eastern part of Louisiana was surrendered to Great Britain, and the western part to Spain as compensation for the Spanish loss of Florida. In 1800, according to the provisions of the secret treaty of San Ildefonso, France regained sovereignty over the western part of the territory. However, in 1803 Napoleon Bonaparte sold the entire US territory.
