The Napoleonic Code served as a foundational model for 19th-century civil law across Latin America, influencing the region through both direct adoption and as a structural template for new national codes.1

In the early 19th century, the code was introduced directly into Haiti and the Dominican Republic, where it remains in force today. Elsewhere, its influence was often mediated through the work of prominent legal scholars. For example, Bolivia and Chile closely followed the arrangement and substance of the French code.1

The Chilean Civil Code, largely the work of Andrés Bello, became a pivotal instrument of legal dissemination. It was subsequently adopted by Colombia and Ecuador, and it exerted a significant influence on the legal systems of Uruguay and Argentina. By the 20th century, however, many Latin American nations—such as Brazil, Mexico, and Peru—began utilizing a comparative method, integrating ideas from German and Swiss traditions alongside the French model.12
