Father Jorge Mario Bergoglio was 39 years old when Argentina’s military junta seized power in March 1976. The seven years that followed were a time of infernal darkness in his country. Union leaders, students, journalists and other left-wing activists were rounded up on the mere suspicion of “subversion.” Many were tortured and raped, or tossed alive from military airplanes into the mouth of the Plata River. As many as 30,000 Argentines were murdered or went missing.
