Práxedis Gilberto Guerrero Hurtado (28 August 1882 – 30 December 1910) was a Mexican anarchist poet, journalist and fighter who served as an insurgent leader during the 1910 Revolution. Biography Guerrero was originally from Los Altos de Ibarra near León, Guanajuato, where his parents owned a hacienda. After finishing his secondary schooling, he began working as a labourer. In 1899 he submitted his first articles to the newspapers El Heraldo Comercial and El Despertador. In 1901, appointed him a correspondent on Diario del Hogar and, that same year, he enlisted as a reservist in the National Army, where he reached the rank of second lieutenant (cavalry).
