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.
