Luis Vicente Cabrera Lobato was a Mexican lawyer, politician and writer. His pen name for his political essays was "Lic. Blas Urrea"; the more literary works he wrote as "Lucas Rivera". During the late presidency of Porfirio Díaz, he was a vocal critic of the regime. He became an important civilian intellectual in the Mexican Revolution (1910-1920).

The Mexican Revolution was an extended sequence of armed regional conflicts in Mexico from 20 November 1910 to 1 December 1920. It has been called "the defining event of modern Mexican history" and resulted in the destruction of the Federal Army, its replacement by a revolutionary army, and the transformation of Mexican culture and government. The northern Constitutionalist faction prevailed on the battlefield and drafted the present-day Constitution of Mexico, which aimed to create a strong central government. Revolutionary generals held power from 1920 to 1940. The revolutionary conflict was primarily a civil war, but foreign powers, having important economic and strategic interests in Mexico, figured in the outcome of Mexico's power struggles; the U.S. involvement was particularly high. The conflict led to the deaths of around one million people, mostly noncombatants.
