Nationalist Mexico is the name given to Mexico during its rule by dictator Gustavo Sáenz de Sicilia from the end of the Mexican Civil War to its fall in 1971. It was founded by Sáenz as the Nationalist Devoirist Party of Mexico in 1922, based on the principles of the Roman Catholic extreme right, extreme nationalism, and a strong central government. It grew in popularity during the Great Depression. In 1937 the "Nationalists" as they were referred to, stormed the Emperor's Palace in Mexico City, executed Emperor Albert II, abolished the monarchy, and proclaimed Sáenz as the new president for life. At the same time, the democratic, liberal Sonora Movement of the north refused to accept an authoritarian government, and civil war broke out. With the support of other National Socialist nations, especially the Confederate States, the Nationalists achieved victory in 3 years. Mexico remained neutral during World War II, though the government vocally supported the Axis.
In 1946, Mexico found itself in the awkward position of being the only National Socialist nation left on Earth. As the years went on Mexico became increasingly unstable, and many citizens began to oppose the devoirist government. In the 1950s, Saenz's main opponents became unitarian communist rebels led by Gustavo Diaz Ordaz. Full blown revolution broke out in 1961, with Saenz fleeing the country. The United States secretly attempted to install their own strongman, but Ordaz and his unitarians successfully took control of the government and established the People's Republic of Mexico.
