In April 1980 Abdul Fattah Ismail, the hardline Marxist head of state of the People's Democratic Republic of Yemen (South Yemen), was pushed from power and went into exile in Moscow, replaced by the more pragmatic Ali Nasir Muhammad, in a bloodless change within the ruling Yemeni Socialist Party. Ismail had become South Yemen's de facto leader and formal head of state in December 1978 and had aligned the country closely with the Soviet Union, but his dogmatic economic policies, his interventionist foreign policy, and his mismanagement cost him support, including that of his Soviet sponsors. In April 1980 he resigned from all his posts, officially citing ill health, and moved to Moscow; Ali Nasir Muhammad succeeded him.
The change was bloodless, and Ismail was allowed to keep a nominal party title before going abroad. The dataset dates this April 2, 1980 and codes his fate as fled the country, reflecting his departure into exile.

Editorial Note
Arc link: this April 1980 removal connects to the recurring bloodletting at the top of South Yemen's ruling party, including the June 1978 execution of Ismail's predecessor Salim Rubai Ali (enriched in an earlier batch); unlike that violent purge, Ismail's ouster was bloodless and ended in exile rather than death. Fate coding: the dataset codes fled the country, matching Ismail's departure into exile in Moscow; he was not physically harmed at the removal. Date nuance: the dataset dates this April 2, 1980, while sources give Ismail's formal resignation as April 21, 1980; the discrepancy is recorded, with the removal placed in April 1980 either way. Coding note: the dataset labels this a palace coup, accurately, as it was an internal change within the ruling Yemeni Socialist Party in which the hardline leader was eased out in favor of a more pragmatic rival, reportedly with Soviet acquiescence. Framing recorded: the official reason was ill health, but sources describe it as a factional ouster driven by economic mismanagement and lost Soviet confidence; both are recorded. Tragic later turn flagged: Ismail returned in 1985 and died in the January 1986 South Yemen civil war between his and Ali Nasir's factions, a separate later event.
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: Head of state Abdul Fattah Ismail, removed in April 1980 and sent into exile in Moscow; he was not physically harmed at the removal but left the country..
Baseline coding: Incumbent executive removed from power. Recorded leader fate: deposed; fled the country. The baseline file does not name individual targets; researched names are kept in a separate layer.
