[1] The magazine was directed and published by Alberto Ghiraldo in Buenos Aires, from 3 March 1904 to 6 February 1905; from October 1904 until it ceased publication, it appeared as a weekly supplement to the daily paper La Protesta.
[1] The magazine began operations from an editorial office near the Avenida de Mayo, but eventually moved to Ghiraldo's own home; it was ultimately closed by a police raid.
It advocated an anarchist ideology and was conceived as part of the movement among Argentine workers against the Law of Residency[2] directed against foreign trade union leaders and activists.
[1] Anarchist ideology, traditionally characterized by the bourgeois press as the work of "foreign agitators", was presented by Martin Fierro as rooted in the gaucho life and identity, by means of stories, poems, illustrations, and sociological notes and articles.
[1] Ghiraldo's connections to a broad cast of intellectuals such as Roberto Payró, Carlos de Saussens, Manuel Ugarte, José Ingenieros, Ricardo Jaimes Freyre, Carlos Baires, Juan Mas y Pi, Eduardo Schiaffino, Evaristo Carriego, Alfredo Palacios and Rubén Darío, all of whom published in the magazine, broadened the readership of Martin Fierro beyond the anarchist camp.
