The National Reorganization Process was the military dictatorship that ruled Argentina from 1976 to 1983, which received support from the United States until 1982. In Argentina it is often known simply as the última junta militar, última dictadura militar or última dictadura cívico-militar, because there have been several in the country's history and no others since it ended.

An enforced disappearance is the secret abduction or imprisonment of a person with the support or acquiescence of a state followed by a refusal to acknowledge the person's fate or whereabouts with the intent of placing the victim outside the protection of the law. Often, forced disappearance implies murder whereby a victim is abducted, may be illegally detained, and is often tortured during interrogation, ultimately killed, and the body disposed of secretly. The party committing the murder has plausible deniability as there is no evidence of the victim's death.
