Indonesia, 1960 — auto-coup

Indonesia (IDN)Southeast Asia, AsiaMarch 5, 1960

Event Summary

On March 5, 1960, President Sukarno of Indonesia suspended the elected parliament, the People's Representative Council (DPR), after it moved to reject his government's 1960 budget, and soon replaced it with an appointed body. The step was a decisive consolidation of Sukarno's Guided Democracy, the authoritarian system he had begun in 1959 by reinstating the strong-executive 1945 constitution and dissolving the constituent assembly. Having dismissed the elected DPR, Sukarno created in its place the Mutual Cooperation House of Representatives (DPR-GR), whose members he appointed rather than elected, drawing many from functional groups including the military and giving substantial representation to the Communist Party.

In September 1960 he added a Provisional People's Consultative Assembly as the nominal highest authority. These moves ended Indonesia's parliamentary democracy and concentrated power in Sukarno's hands, with no national election held again until after Suharto took over.

In March 1960 the DPR unexpectedly rejected Sukarno's government budget, and he then dissolved the House and replaced it with the Mutual Assistance House of Representatives (DPR-GR), whose members were the president's appointees rather than the deputies elected in 1955.

Editorial Note

The Cline dataset codes this an auto-coup on 5 March 1960 with no one physically harmed; the primary FRUS cable confirms Sukarno suspended parliament on 5 March, matching the dataset exactly. Three Wikipedia-derived sources and the FRUS cable were read directly. This self-coup consolidated Guided Democracy and ended Indonesian parliamentary democracy until the Suharto era.

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.
