In this article, the impact of the democracy of the concurrent par-ties in a free trade agreement was evaluated with the depth of the commitments acquired within the framework of the respective treaties. This argument was reviewed through the evaluation of variables that accounted for arguments based on liberal tradi-tions of international relations, specifically democracy, applied to the links reached in free trade agreements. Although the results would confirm these perspective arguments, the greater rele-vance to account for a greater deepening of commercial links corresponds to contextual factors, such as the 1990s and 2000s. In carrying out this research, updated information on 692 free trade agreements signed between 1948 and 2020, using linear regressions with multilevel structure adjustment.
