Mexico - The Aleman Sexenio, 1946 52

Alemán's presidency was also noteworthy because it represented the consolidation in power of a PRI faction that was more probusiness and less nationalistic than the Cárdenas wing of the party. One of Alemán's first acts as president was to reaffirm amicable postwar relations between Mexico and the United States. In a symbolic gesture of rapprochement, United States President Harry S Truman and President Alemán visited each other's countries. On September 2, 1947, Mexico was among the signatories of the Inter-American Treaty of Reciprocal Assistance (Rio Treaty), which outlined a system of mutual defense on the part of Western Hemisphere nations against outside aggression.

Alemán was viewed as much less sympathetic than his immediate predecessors to the demands of labor and the rural populations of central and southern Mexico. To promote growth without generating high inflation, the government acted through the PRI-affiliated unions to suppress the wage demands of labor. The government also began a new strategy of "stabilizing development." The new program was based on promoting industrialization through import substitution (see Glossary), heavy subsidies of industry, and maintaining low inflation by suppressing real wages.

The Alemán presidency marked a turning point in contemporary Mexican politics. With the election of Alemán (a lawyer by profession), the torch was passed to a new generation of civilian politicians who had not participated in the military campaigns of the Revolution. The age of the generals in Mexican politics was over. Henceforth, the military assumed a low profile, surrendering many of its institutional prerogatives to a civilian-dominated PRI.

The Alemán administration attempted to promote industrialization and economic growth by embarking on an extensive program of infrastructure improvements. Major flood control and irrigation projects were built in northern Mexico, greatly expanding the opportunities for large-scale agribusiness. The exploitation of cheap hydroelectric power and the expansion of the national road network were undertaken to help spur heavy industry and tourism. By the end of Alemán's sexenio in 1952, Mexico had four times as many kilometers of paved roads (roughly 16,000 kilometers) as in 1946. Another legacy of the Alemán era was the completion in 1952 of a new campus--in what was then suburban Mexico City--for the flagship of the Mexican university system, the National Autonomous University of Mexico (Universidad Nacional Autónoma de México--UNAM).

Further straying from the ideals of the Revolution, Alemán's administration became noted for its tolerance of official corruption. The government's growing involvement in the economy provided ample opportunities for kickbacks and other forms of illicit enrichment, and several senior government officials became wealthy while in office. The scale of official venality was enough to spark a public outcry and protests from within the PRI. To restore popular faith in the ruling party, Alemán nominated Adolfo Ruiz Cortines, a former governor of Veracruz, minister of interior, and a man noted for his impeccable character, to succeed him in 1952.
