On February 3, 1977 Colonel Mengistu Haile Mariam seized undisputed control of Ethiopia's ruling Derg in a bloody shootout in Addis Ababa that killed the nominal head of state, Brigadier General Tafari Benti, along with several other Derg members, clearing the way for Mengistu's dictatorship and the Red Terror. Since the Derg had deposed Emperor Haile Selassie in 1974, power within the military council had been contested, and by late 1976 a faction around Tafari Benti had moved to limit Mengistu's authority. On February 3, 1977, soldiers loyal to Mengistu under Lieutenant Colonel Daniel Asfaw arrested Tafari and several suspect Derg members at a meeting; they were then shot dead in a garage on the compound.
A later shootout that evening killed Daniel Asfaw and others. Mengistu announced over Radio Ethiopia that Tafari and his associates had been killed as secret supporters of the rival Ethiopian People's Revolutionary Party. With his rivals dead, Mengistu became chairman of the Derg and head of state and soon launched the Red Terror.

Mengistu did not emerge as the leader of the Derg until after the 3 February 1977 shootout, in which Chairman Tafari Benti was killed, and the rivalry within the Derg was resolved at that meeting of the Standing Committee where a number of top Derg officers were killed, seven of them opponents of Mengistu including chairman Lieutenant General Tafari Benti.

Lieutenant General Tafari Benti, Ethiopia's nominal head of state as Chairman of the Derg, was executed along with six other Derg members after a gun battle between rival factions during a meeting in Addis Ababa, after which Mengistu announced that Benti and the others had been exposed as supporters of the counter-revolutionary Ethiopian People's Revolutionary Party, and Mengistu then became the new Chairman of the Derg and launched the Red Terror.
SOURCE REVIEWEDWikipedia, February 1977open source ↗
During a routine meeting on 3 February 1977 Tafari and other Derg members suspected of conspiring with the EPRP were arrested by soldiers under the command of Lieutenant Colonel Daniel, led into a garage, and then soldiers armed with automatic weapons and silencers assassinated Tafari and the suspect Derg members, after which Radio Ethiopia broadcast Mengistu's charge that they had been killed because they were secret supporters of the EPRP.
In February 1977 Mengistu survived a battle between his supporters and those of rivals on the ruling council, Banti and several other members were killed, and Mengistu seized complete power as chairman and head of state, then countered the EPRP's White Terror with his own Red Terror that continued into 1978 and killed as many as 100,000 people.
Killings protocol applied: the deposed head of state Tafari Benti was killed, along with several other Derg members, and every death claim is cited and attributed. Casualty count varies across sources: some say Tafari plus six others (seven total), others describe eight or fifty-eight officers killed in the hour-long shootout; the record records this range rather than fixing one figure. Note the dataset id carries a '_2' suffix (53002031977_2), distinguishing this February 3 1977 Ethiopia entry from another same-dated record. Coding note: the dataset labels this a palace coup with a killed fate, accurately, as it was an internal power seizure within the ruling Derg in which the sitting chairman was killed. Arc link: this connects to the Derg's 1974 seizure of power and deposition of Haile Selassie (the 1974 Ethiopia records enriched in batch 26), and it inaugurated the Red Terror (Qey Shibir), whose death toll estimates range enormously (from tens of thousands to hundreds of thousands) and are recorded as contested, not resolved. Mengistu was convicted of genocide in absentia in 2006, later context.
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: Brigadier General Tafari Benti, the Derg chairman and head of state, killed on February 3, 1977 in the shootout through which Mengistu seized full power..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; killed. The baseline file does not name individual targets; researched names are kept in a separate layer.
