History of Bolivia (1964–1982)

The history of Bolivia from 1964 to 1982 is a time of periodic instability under various military dictators. On November 4, 1964, power passed from the elected leader of the Bolivian National Revolution, Víctor Paz Estenssoro, to a military junta under vice-president General René Barrientos. Barrientos was elected president in 1966 but died suspiciously in a helicopter crash in 1969 while touring the countryside and visiting the indigenous people of Bolivia. This led to a coup in September 1969 by General Ovando, who was overthrown in October 1970 by General Rogelio Miranda, who was overthrown a couple of days later by General Juan José Torres, who in turn was overthrown in August 1971 by Hugo Banzer Suárez. Banzer ruled for seven years, initially from 1971 to 1974, with the support of Estenssoro's Nationalist Revolutionary Movement. In 1974, impatient with schisms in the party, he replaced civilians with members of the armed forces and suspended political activities. The economy grew impressively during Banzer's presidency, but demands for greater political freedom undercut his support. He called elections in 1978, and Bolivia once again plunged into turmoil. Juan Pereda ruled for only four months in 1978, but his ascent to the presidency marked the beginning of an even more unstable period in Bolivian history, with nine civilian and military presidents in little over four years (1978–1982). 1982 marked the return to a democratically elected government, with Guido Vildoso as president.
