The National Reorganization Process was the military dictatorship that ruled Argentina from 1976 to 1983. In Argentina it is often known simply as última junta militar, última dictadura militar or última dictadura cívico-militar, because there have been several in the country's history.
The Argentine military seized political power during the March 1976 coup against the presidency of Isabel Perón, widow of former President Juan Domingo Perón; a time of state terrorism against civilians started, with the new dictatorship labeling its own use of torture, extrajudicial murder and systematic forced disappearances as "a Dirty War". After starting and then losing the Falklands War to the United Kingdom in 1982, the military junta faced mounting public opposition and finally relinquished power in 1983.
Almost all of the surviving junta members are currently serving sentences for crimes against humanity and genocide.
