When the Imperial forces, in 1863, took possession of Guadalajara, Ireneo Paz withdrew to Colima, where he was editor of the Official Periodical of that State, and Magistrate of the Court of Justice. A year later, the approach of the Imperialists forced him to abandon these offices. He was with the Federal forces of the coast until their rout at Zapotlan, when he was one of the three to arrange the terms of capitulation with General Oroñoz. He was kept under surveillance at Guadalajara, where he, nevertheless, dedicated himself to the Republican cause, establishing _El Payaso_ (The Clown), which vigorously combatted monarchical ideas, with audacity and satire--replacing it later by _El Noticioso_ (The Well-Informed). Maximilian himself was impressed by the little sheet and ordered that a full set should be secured for him. On the occasion of an operatic triumph, at Guadalajara, by the prima donna, Angela Peralta,--Ireneo Paz gave vent to some democratic sentiments, which led to his arrest and imprisonment on November 12, 1866. His stay there was brief, as the Republican forces gained possession of the town, one month later. With the full re-establishment of the Republic, he was appointed in 1867 Secretary of State for Sinaloa. A few months later, he was again actively interested, against Juarez, in favor of the ideas of Diaz. The opposition failed and Paz was again in prison, this time in Santiago Tlaltelolco; he was later transferred to La Députacion. During his eleven months in prison, he vigorously assailed the Juarez regime in the popular anti-administration journal, _El Padre Cobos_ (Father Cobos). After his release, he continued his attacks in newspaper articles, in popular clubs, and in the secret plottings preceding the revolution known as La Noria. Notwithstanding all the efforts against him, Juarez was re-elected in 1871, but shortly died. Ireneo Paz was active in the revolution of La Noria and in that of Tuxtepec, four years later--supporting Diaz on both occasions and suffering imprisonment twice. The mere list of the books written by Ireneo Paz is too long for quoting here. Many of them are historical novels dealing with Mexican themes. He has written too much for all of it to have great literary merit, but he is widely read and well known. His style is often tedious and prolix, but many interesting, and even thrilling, passages occur in his works. He has a quiet and dry humor and, sometimes, keen satire. His _Algunas Campañas_ (Some Campaigns), is practically a history of events in which he himself has participated. Our quotations are from it. In poetry Paz ranges from satire to love, from humor to philosophy.
