On November 9, 1974 President Hugo Banzer of Bolivia carried out a self-coup, issuing Supreme Decree 11947 that dissolved his civilian party allies, banned all political activity, and placed the executive entirely under the armed forces, converting his three-year-old government into an openly military dictatorship. Banzer had seized power in August 1971 backed by a civil-military coalition, the Nationalist Popular Front, that included the MNR of Victor Paz Estenssoro and the Bolivian Socialist Falange. That coalition disintegrated through 1973 and 1974 as the parties realized Banzer did not intend to hold the promised 1974 elections.
After surviving two 1974 coup attempts, including a June tank revolt led by Gary Prado and a November 7 uprising in Santa Cruz, Banzer concluded he no longer needed civilian partners. Inspired by the Chilean and Brazilian military models, he decreed on November 9 the recess of all political parties, government by the armed forces until 1980, and the suspension of union, business, and student political activity, exiling major party leaders including Paz Estenssoro. He ruled by the military alone until 1978.

Supreme Decree 11947, issued on November 9, 1974 by the military government of Hugo Banzer, declared the recess of political parties and the complete militarization of the Executive Branch, beginning a new stage of the Banzer regime, and was caused by the breakup of the Nationalist Popular Front, the alliance of the armed forces with the MNR and the FSB.
The decline of the Front and a coup attempt convinced Banzer that he no longer needed civilian allies, and inspired by the Chilean and Brazilian model he announced a complete reorganization in Supreme Decree 11947 of 9 November 1974, whose objectives were the recess of political parties, government run exclusively by the Armed Forces until 1980, and the cessation of political activities of unions, business, and student organizations.
Banzer ruled with a measure of civilian support until 1974, when the main parties realized he did not intend to hold elections and was instead using them to perpetuate himself in power, at which point Banzer dispensed with all pretenses, banned all political activity, exiled all major leaders including Paz Estenssoro, and proceeded to rule henceforth solely with military support.
The coalition government broke down on November 9, 1974, when President Banzer enacted Supreme Decree 11947, which banned political activity and made the Bolivian army assume total control of the country, after he had survived a June 1974 tank revolt led by Gary Prado and a November 7 uprising in Santa Cruz.

Editorial Note
Arc link: this November 1974 self-coup connects to Banzer's original August 22, 1971 coup against Juan Jose Torres (enriched in batch 21); it is Banzer discarding his civilian coalition to rule as an outright military dictator. Coding note: the dataset labels this a military coup and codes the fate not physically harmed; it was in effect an auto coup by decree (Supreme Decree 11947) in which the sitting president dissolved his own coalition and the civilian political order, with the displaced party leaders exiled rather than harmed. Date nuance: the decree was November 9, 1974 (the dataset date is November 8), issued days after the November 7 Santa Cruz uprising. Arc forward: Banzer was forced to allow elections and was ousted by Juan Pereda in 1978, beginning a chaotic run of Bolivian coups, separate later events.
Cross-Reference
Only one dataset carries it. One of the three reference datasets we check against carries this event; the others do not list it. That is not a contradiction — the datasets cover different periods and use different thresholds — but it means the record has had less outside corroboration.
Identifiers for finding this same event in the other datasets:
Coup Atlas research identifies the target as: The civilian coalition partners and the constitutional order, displaced by President Banzer's own November 9, 1974 self-coup; as an auto coup the sitting president was the beneficiary and no one was physically harmed. Party leaders such as Paz Estenssoro were exiled..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; not physically harmed. The baseline file does not name individual targets; researched names are kept in a separate layer.
