Louisiana's civil law system is what the majority of nations in the world use, especially in Europe and its former colonies, excluding those that derive their legal systems from the British Empire. However, it is incorrect to equate the Louisiana Civil Code with the Napoleonic Code. Although the Napoleonic Code and Louisiana law draw from common legal roots, the Napoleonic Code was never in force in Louisiana, as it was enacted in 1804, after the United States had purchased and annexed Louisiana in 1803.
