On February 5, 1975 General Gabriel Ramanantsoa of Madagascar, unable to govern amid mounting economic, ethnic, and military tensions, resigned and handed full power to his interior minister, Colonel Richard Ratsimandrava, a transfer that lasted only six days before Ratsimandrava was assassinated. Ramanantsoa had ruled since taking power from President Tsiranana in the 1972 rotaka upheaval, pursuing a nationalist, moderately leftist course that removed French forces, cut ties with South Africa, and drew closer to the communist bloc. But his military regime could not resolve rising economic problems and ethnic strife, and on December 31, 1974 it faced an unsuccessful coup attempt.
In this crisis Ramanantsoa stepped aside on February 5, 1975, transferring executive power to Ratsimandrava, a respected officer and former minister of the interior who now combined the offices of president, prime minister, and defense and planning minister. Ratsimandrava's tenure was extraordinarily brief: on the night of February 11 to 12, 1975, he was assassinated, and a military directorate took over.

In the wake of political and social unrest, on February 5, 1975 Ramanantsoa handed power over to a former minister of the interior, Colonel Richard Ratsimandrava, after his military regime, which had pursued nationalist policies including removing French forces and establishing ties with the Soviet Union, could not resolve rising economic problems.

On February 5, 1975, Ramanantsoa gave full powers to Richard Ratsimandrava, who combined the functions of President of the Republic, Prime Minister, and Minister of National Defense and Planning, and on the night of 11 to 12 February 1975, after the assassination of Ratsimandrava, a military executive led by General Gilles Andriamahazo took power.
The Ramanantsoa military regime could not resolve rising economic and ethnic problems, and on December 31, 1974 the armed forces launched an unsuccessful coup, preceding Ramanantsoa's February 1975 decision to hand power to Ratsimandrava.

Editorial Note
Arc link: this February 1975 transfer connects to the Madagascar pair enriched in batch 24, Tsiranana's fall in the 1972 rotaka (1972-05-09) and formal departure (1972-10-11) that first brought Ramanantsoa to power; this record is Ramanantsoa in turn handing off amid crisis. Fate coding: the dataset codes the February 5 event not physically harmed, matching Ramanantsoa's peaceful resignation and handover. Critical distinction: Ratsimandrava, the man who took power on February 5, was assassinated on the night of February 11 to 12, 1975, which is a SEPARATE later event (leading to the Andriamahazo military directorate and then Ratsiraka's rise), and is recorded here only as immediate aftermath, not as the fate of this February 5 dataset record. Context: a December 31, 1974 coup attempt preceded the handover.
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: General Gabriel Ramanantsoa, who resigned and handed power to Colonel Richard Ratsimandrava on February 5, 1975; Ramanantsoa was not physically harmed. Ratsimandrava was assassinated six days later, a separate event..
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.
