Introduction
Until the Mercosur was created, Latin America had worked for the unification of its commercial market for a long time but usually with negatives results.
In February 25, 1948, the CEPAL (Economic Commission for Latin America) was created with the purpose of studying the international trade and promoting local industries. This treaty put emphasis on the external factors that hindered the development of Latin American countries, instead of looking for internal factors. That was one of the reasons why this treaty failed.
