Manuel Ávila Camacho was the 52th President of Mexico from 1940 to 1946. He is best known for shifting the nation toward industrialization and fostering moderate relations with the United States during the Second World War. His administration also stabilized domestic policy by cooling tensions between the state and the Roman Catholic Church.
The Mexican presidency between 1940 and 1946 marked a strategic shift toward internal industrialization and normalized international relations under the administration of Manuel Ávila Camacho. Navigating the geopolitical tensions of the Second World War, he transitioned the nation away from the radical socialist policies of his predecessors, fostering a climate of moderation, religious reconciliation, and economic alignment with the United States.
Military Career and Rise to Power
Born in 1897 in Teziutlán, Puebla, Ávila Camacho joined the revolutionary forces in 1914 as a second lieutenant. By 1920, he held the rank of colonel and served as the chief of staff for Michoacán, where he developed a significant political and personal bond with Lázaro Cárdenas. Following his service against the 1923 Adolfo de la Huerta rebellion and the 1929 Escobar Rebellion, he was promoted to brigadier general. His ascent to the presidency followed his tenure as Secretary of National Defense, which he held from 1936 until 1939, culminating in a contested electoral victory over Juan Andreu Almazán.

Upon assuming office, the president sought to stabilize the nation by softening the militant secularism that characterized post-revolutionary governments. As a practicing Roman Catholic, he publicly declared his faith, effectively cooling long-standing tensions between the church and the state. His domestic agenda included the establishment of the Mexican Social Security Institute in 1943 and the introduction of rent controls for low-income citizens. He also worked to modernize agricultural output by inviting the Rockefeller Foundation to implement new technology, while simultaneously repealing socialist education mandates.
Wartime Diplomacy and International Alignment
The destruction of Mexican oil tankers by German submarines forced a declaration of war against the Axis powers on 22 May 1942. This shift facilitated a new era of cooperation with the United States, characterized by the Bracero program, which supplied 300,000 workers to support the American war effort. Mexico contributed the 201st Air Squadron to the Pacific theater, participating in the Battle of Luzon. By the war's end, the administration had restored diplomatic ties with the United Kingdom and the Soviet Union and finalized Mexico's entry into the United Nations.
Political Consolidation
In 1946, the president transformed the Party of the Mexican Revolution into the Institutional Revolutionary Party. This restructuring removed the military as an official sector of the party and enacted strict electoral laws requiring political organizations to maintain significant membership levels across multiple states. His administration also prioritized rapid industrial growth, which saw production increase by approximately 10 percent annually during the war years, though these gains were accompanied by rising income inequality.
