On August 29, 1975 President Juan Velasco Alvarado of Peru was deposed in a bloodless institutional coup, sometimes called the Tacnazo, in which his own prime minister and armed forces commander, General Francisco Morales Bermudez, took over the leadership of the military government, ending the first, radical phase of Peru's Revolutionary Government of the Armed Forces. Velasco had seized power in 1968 and pursued a leftist, nationalist program of agrarian reform, nationalizations, and non-aligned foreign policy, but by 1975 the country faced deep economic crisis, his health had declined after a serious illness and the amputation of a leg, and the officer corps had grown wary of the regime's direction and disorder. On August 29, 1975 senior officers led by Morales Bermudez, then prime minister and army commander, moved against Velasco in a pronunciamiento launched from Tacna; Velasco stepped down without violence and Morales Bermudez assumed the presidency, inaugurating the more conservative second phase of the military government.
Velasco was not physically harmed and retired from public life.

Editorial Note
Coding note: the dataset labels this a palace coup, accurately, as it was an internal takeover within the ruling military government, with Velasco's own prime minister and army commander Morales Bermudez replacing him; Velasco was not physically harmed, matching the dataset fate. Context: Velasco led the radical first phase (agrarian reform, nationalizations, non-alignment) of the 1968 to 1980 military government; the 1975 Tacnazo opened the conservative second phase that gradually walked back his reforms and led to the 1980 return to civilian rule. Health factor: Velasco's serious illness and leg amputation weakened his position and are recorded as a contributing factor. Arc link: this connects to Velasco's own October 3, 1968 coup against Belaunde (enriched in batch 20).
