Alberto Fujimori served as president of Peru from 1990 to 2000 (Britannica). His presidency is the textbook modern self-coup, and Sergei Guriev and Daniel Treisman name him as a pioneer of the spin dictator model (Wikipedia summary of Spin Dictators).
The April 5, 1992 self-coup
In an address to the nation on April 5, 1992, Fujimori announced the "temporary closure" of the opposition-controlled Congress and set up a "National Reconstruction Government" (Andina). The judiciary, the National Council of the Magistracy, the Public Ministry and the Comptroller General's Office were reorganised and most of the judiciary replaced (Andina).
The armed forces backed the move: tanks and soldiers were sent into the streets of Lima, soldiers guarded the closed Congress and tanks stood at the Palace of Justice, military forces ensured government control over the media, and the president of the Chamber of Deputies was arrested at his home. The newspaper La República protested by publishing blank pages (Andina).
Fall and accountability
Fujimori was forced from office in 2000 amid corruption allegations and fled to Japan, later travelling to Chile, from which he was extradited to Peru in 2007 (Britannica). In April 2009 he was sentenced to 25 years in prison (Al Jazeera, April 8, 2009) over killings by a military squad, including the 1991 Barrios Altos massacre, in which 15 people died, and the La Cantuta killings of nine students and a professor (Al Jazeera). He died in Lima on September 11, 2024 (Britannica).
Playbook parallels
Peru illustrates Pillar 3 (aggrandizing executive power) and Pillar 1 (capturing independent institutions) of the Seven Pillars, executed in a single night with military backing. It is also an example of eventual accountability through domestic courts.
