Changes

The Nationalist Revolutionary Movement (MNR) emerged as a broadly based party. Denied its victory in the 1951 presidential elections, the MNR led the successful 1952 revolution. Under President Victor Paz Estenssoro, the MNR introduced universal adult suffrage, carried out a sweeping land reform, promoted rural education, and nationalized the country's largest tin mines.

Twelve years of tumultuous rule left the MNR divided. In 1964, a military junta overthrew President Paz Estenssoro at the outset of his third term. The 1969 death of President [[Rene Barrientos]], a former member of the junta elected President in 1966, led to a succession of weak governments. Alarmed by public disorder, the military, the MNR, and others installed Col. (later General) Hugo Banzer Suarez as President in 1971. Banzer ruled with MNR support from 1971 to 1974. Then, impatient with schisms in the coalition, he replaced civilians with members of the armed forces and suspended political activities.

The economy grew impressively during most of Banzer's presidency, but human rights violations and eventual fiscal crises undercut his support. He was forced to call elections in 1978, and Bolivia again entered a period of political turmoil. Elections in 1978, 1979, and 1980 were inconclusive and marked by fraud. There were coups, counter-coups, and caretaker governments.

In 1980, Gen. Luis Garcia Meza carried out a ruthless and violent coup. His government was notorious for human rights abuses, narcotics trafficking, and economic mismanagement. Later convicted in absentia for crimes, including murder, Garcia Meza was extradited from Brazil and began serving a 30-year sentence in 1995.

After a military rebellion forced out Garcia Meza in 1981, three other military governments in 14 months struggled with Bolivia's growing problems. Unrest forced the military to convoke the Congress elected in 1980 and allow it to choose a new chief executive. In October 1982–22 years after the end of his first term of office (1956–60)--Hernan Siles Zuazo again became President. Severe social tension, exacerbated by economic mismanagement and weak leadership, forced him to call early elections and relinquish power a year before the end of his constitutional term.
