What is "regeneracion"

Regeneración 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.
