Regeneración (Spanish: [rexeneɾaˈsjon]) was a Mexican anarchist newspaper that functioned as the official organ of the Mexican Liberal Party. Founded by the Flores Magón brothers in 1900, it was forced to move to the United States in 1905.Jesús Flores Magón published the paper (along with Anselmo Figueroa, a leading member of the party), while his brothers Ricardo and Enrique contributed articles. The Spanish edition of Regeneración was edited by Ricardo, and the English version by W. C. Owen and Alfred G. Santleben.
It was a major source of reports and analysis on the Mexican Revolution and Spanish-speaking America, sharply critical of the United States and Mexican governments which collaborated in repressing the publication.
In September 1910, Regeneración published the stories of three 1908 revolutionary episodes, in which the Mexican journalist and insurgent leader Práxedis Guerrero described PLM attacks on the settlements of Las Vacas (modern-day Ciudad Acuña, Coahuila), Viesca, Coahuila, and Puerto Palomas, Chihuahua, intended to spark a social revolution across Mexico.
