Institutional Revolutionary Party
The Institutional Revolutionary Party (, PRI) is a Mexican political party founded in 1929 that held uninterrupted power in the country for 71 years from 1929 to 2000, first as the National Revolutionary Party (, PNR), then as the Party of the Mexican Revolution (, PRM), and finally renaming itself as the Institutional Revolutionary Party in 1946.
Liberalism in Mexico
As the Díaz regime became increasingly dictatorial and trampled on the rights and liberties of Mexicans, a group of Mexican oppositionists led by Camilo Arriaga and Ricardo Flores Magón formed the Mexican Liberal Party (PLM). It called for the overthrow of Díaz and agitated for the rights of workers and peasants and for economic nationalism favoring Mexicans rather than foreigners. The PLM had two basic factions, one was reformist and was supported by elite, urban intellectuals and the other was anarcho-communist and advocated revolution. As the opposition to Díaz grew, Liberal clubs met secretly in Mexican cities to discuss politics, which led to the First Liberal Congress that met in San Luis Potosí in 1901. Radicals, such as Flores Magón, were exiled to the United States and drafted the Liberal Party program in 1905. A reformist liberal, rich hacienda owner Francisco I. Madero founded the Anti-Reelectionist Party and ran against Díaz in the 1910 presidential elections. He garnered support from PLM members in the campaign. The fraudulent 1910 elections sparked revolts throughout many parts of the country, considered the outbreak of the Mexican Revolution, and Díaz was forced to resign.
