AbstractThe debate regarding whether the origin of Louisiana civil law is based in the Spanish or in the French legal tradition has been ongoing since that state's incorporation into the United States as a result of the Louisiana Purchase. Distinguished legal scholars have argued in favor of one tradition being dominant over the other, and each has been staunch in support of that view. This article proposes and demonstrates that the Spanish, not French, civil law had an enormous influence on the creation and evolution of Louisiana civil law, and that this legacy resonates today.
