1956 Mexican coup d'état

The 1956 Mexican coup d'état was a covert military operation orchestrated by the collective intelligence agencies of Brazoria, Missouri, Sierra, and the United Commonwealth through the which deposed democratically elected Mexican President Soledad Solis and ended the Mexican Revolution of 1955. The coup was one of the first of several covert operations and political interventions in by the Anglo-American powers during the, and resulted in nearly 20 years of authoritarian rule under President Francisco Alarcón, a right-wing general who led the coup.

In 1955, there was a popular uprising led by Mexican socialist and leftist revolutionaries against the presidency of Umberto Ruiz. Although Ruiz was a member of the historically left-wing (PRI) (which had operated de facto one-party rule since the end of the Revolution), he and his predecessors since the conclusion of, shifted the policies of the party towards the right, in support of the international business community and social conservatives, which was seen as a betrayal to the principles and ideals of the. Ruiz repressed labor strikes and political demonstrations prolifically during his administration, and held extensive ties with foreign companies centered in the Yucatán, which included agriculture and mining companies. Ruiz was impeached on the grounds of corruption and bribery in 1955 and was constitutionally removed by members of his own party in the Mexican Congress. Thereafter, elections were held and Soledad Solis, a left-wing populist, was elected as the new president, and new leader of the Institutional Revolutionary Party.

Solis passed far-reaching reforms on land and labor, outlawing various practices of businesses which were allowed under Ruiz, and strengthened worker conditions through introducing a series of regulations directed against the private community. He also sought to nationalize the petroleum industry, which had up until that point, been managed by a number of multinational firms with connections with the Mexican political elite. He also sought to move away from relying on Anglo-America for support, seeking to adopt a neutral foreign policy and aligning closer with other fellow Latin American nations. With his reforms seen as a threat to private interests, and a dangerous precedent of socialism that could be replicated throughout the rest of Latin America, the Anglo-American community cooperated together in engineering a military coup which would oust Solis from power, and install an administration which would maintain the pro-business and pro-American policies prior to Solis' ascension.
