In June 1927, the "Agrarian Association of Antioquia", (""Sociead Antioqueña de Agricultores"") (S.A.A.), decide to make a second effort to try to organize and confederate the nation's coffee growers. Thus, the Second National Congress of Coffee Growers convened in Medellín in 1927. The main speaker was former President of Colombia Carlos Eugenio Restrepo, who gave the opening speech. Twenty nine delegates participated in this Congress and several dignitaries from the political and economic elite of the nation, and among them two of the sons of Tulio Ospina Vásquez, Rafael Ospina Pérez (president of the S.A.A.) who presided over this Congress and Mariano Ospina Pérez, future president of Colombia. Other participants were Daniel Uribe Botero (vice-president of the S.A.A.), Epifánio Montoya, Julio C. Gaitán (representing the government), Pedro Bernal Escobar and Joaquín Santamaría. By the end of deliberations, the Second National Congress of Coffee Growers had agreed to establish the ""National Federation of Coffee Growers of Colombia"" (Federación Nacional de Cafeteros de Colombia). The Federation was created as a trade association, private entity and non-profit organization. Few months later that same year of 1927, the National Congress approved the Law 76, by which duties were imposed on all exports of the country and gave to the National Federation of Coffee Growers the authority to administer and manage all these revenue. Thus, the Federation and the national government signed a contract, on October 15, 1928, by which the government was obliged to transfer to the Federation all revenue generated by this tax. This revenue propelled and fortified the Federation and these resources were used to create the National Coffee Fund. In 1928, the first regional committee was established as the Coffee Growers Committee of Antioquia ("Comité de Cafeteros de Antioquia"). Mariano Ospina Pérez was its first President, and the first registered member of the association. The first Board of Directors of the newly organized Federación Nacional de Cafeteros de Colombia assembled in Bogotá, on August 3, 1929. Its first members were Mariano Ospina Vásquez, Alberto Camilo Suárez, Gabriel Ortiz Williamson, Carlos Caballero, Jesús del Corral and Mariano Ospina Pérez, for whom the organization of the national coffee industry was one of his most serious and ambitious concerns.
