From the outbreak of the Mexican Revolution in 1910 until his death in 1913, Posada worked tirelessly in the press. The works he completed in his press during this time allowed him to develop his artistic prowess as a draftsman, engraver and lithographer. At the time he continued to make satirical illustrations and cartoons featured in the magazine, "El Jicote". He played a crucial role for the government during the presidency of Francisco I Madero and during the campaign of Emiliano Zapata.
