In 1927, amidst a bloody religious conflict between Catholic partisans and the Mexican state, a 36-year-old priest was charged with plotting against the President-Elect at the time, Alvaro Obregon. After a hastily carried out investigation, he was executed. The present paper analyzes some of the ways in which Pro has been memorialized, linking these processes with the socio-historical conditions prevalent at different times in twentieth century Mexico.  Discussion then moves to some of the modes in which a narrative of martyrdom is made to infuse death with meaning, and how it changes over time to fit different social necessities.
