First civilian Mexican president after the Revolution.
Alemán Valdés assumed the presidency in 1946, marking the first time a civilian held the office since the revolution. His election symbolized the institutionalization of the revolutionary state and the dominance of the Institutional Revolutionary Party (PRI).
Alemán Valdés promoted import-substitution industrialization, building highways, dams, and hydroelectric plants. His policies spurred economic growth but also increased inequality and urban migration, shaping Mexico's modern economy.
Alemán Valdés suppressed independent labor unions and leftist opposition, using the military and police to crush strikes and imprison leaders. This authoritarian turn consolidated PRI control but undermined democratic freedoms.
