On the night of 25 November 1973, hardline officers of the Greek military ousted Georgios Papadopoulos, the colonel who had led Greece's ruling junta since the April 1967 coup, in a bloodless internal coup. The operation was masterminded by Brigadier General Dimitrios Ioannides, chief of the military police (ESA), who emerged as the regime's dominant figure even though he took no formal office himself. The coup followed the junta's violent suppression of the Athens Polytechnic student uprising.
Ioannides installed Lt. General Phaedon Gizikis as president and Adamantios Androutsopoulos as prime minister as figureheads while ruling from behind the scenes; the resulting regime, described as "even more repressive" than Papadopoulos's, collapsed in July 1974 amid the Cyprus crisis, and democratic government was restored. Papadopoulos was later tried for treason and sentenced to death in August 1975; the sentence was commuted to life imprisonment days later.

Brigadier General Dimitrios Ioannides masterminded the coup and, though he held no formal government post, was 'the dominant figure' in the new regime.

Ioannides was Chief of the Military Police (ESA), a unit 'reputed to have been largely responsible for maltreatment of political prisoners' under the junta.

The coup came after student protests (the Athens Polytechnic uprising) were violently suppressed; Papadopoulos was then 'overthrown from within the junta and replaced by the even more repressive Gen. Demetrios Ioannidis.'

Four months after the coup, real power still rested with Ioannides, while the men installed in office — President Phaedon Gizikis and Prime Minister Adamantios Androutsopoulos — were 'political nonentities without a power base.'

The junta that resulted from the November 1973 coup ruled until July 1974, when, amid the Cyprus crisis, 'the military leaders resigned and democratic government was restored.'

After the junta fell, Papadopoulos was tried and, with fellow colonels Nikolaos Makarezos and Stylianos Pattakos, 'received the sentence[] of death... for high treason'; on 25 August 1975 the government commuted the three death sentences to life imprisonment.

Editorial Note
Wikipedia's own footnotes for this event (a 1991 Political Science Quarterly article, a 1975 US Congress Select Committee on Intelligence report, Danopoulos's 1984 "Warriors and Politicians in Modern Greece", and a 2004 Southeastern Europe journal piece) were identified but not directly accessible this session, so no facts were sourced to them as CHAIN; instead I located and directly fetched independent primary/secondary sources (contemporaneous US State Department cables in the published FRUS series, Britannica, EBSCO Research Starters, and a Cambridge University Press journal article) that corroborate the same core facts, all listed as VERIFIED. Sources vary in specificity but do not conflict: Britannica and EBSCO describe the ouster only as occurring in "1973"/"fall of 1973" without a precise date or naming Ioannides, while the FRUS telegram (written the day after, Nov. 26, 1973) gives the exact date (Nov. 25) and names Ioannides explicitly — treated as complementary, not contradictory. One detail I could not independently verify and therefore omitted: Wikipedia's claim that Papadopoulos had formally proclaimed himself "President of the Republic" on 1 June 1973 (confirmed by a 29 July 1973 referendum) carried no accessible inline citation, so it is not included as a sourced fact, though the FRUS cable's references to "the Papadopoulos government" and Britannica's note that "Greece was declared a republic" in 1973 corroborate that he was Greece's head of state/government at the time he was ousted. | Methodology: fetched all five distinct source URLs directly (not trusting the researcher's excerpts), using neutral/non-leading prompts first, then targeted follow-up searches (e.g., searching each document for every use of the word "President") specifically to hunt for oversold claims. All five sources are real, accessible, and their quotes are verbatim-accurate — no fabricated or dead sources found. The one substantive sourcing-honesty problem found: the entry asserts Papadopoulos held the title "President" in both fact 1 and target_leader, labeling both VERIFIED against sources that never use that title for him — while the entry's own notes simultaneously admit this exact "President" claim could not be verified elsewhere and was excluded from the facts list. That is a real inconsistency (unverified claim labeled VERIFIED via a different vehicle), now corrected by removing the unsupported title from both fact 1 and target_leader. Also trimmed one unsourced editorializing clause from the summary ("liberalizing" Papadopoulos / hardliners' stated "justification") that had no corresponding fact. Minor non-substantive improvement: corrected the Cambridge article's source_year from placeholder "n.d." to the actual 2022 publication year, and added the author's name (Hatzivassiliou), confirmed via direct fetch. All other facts (2,3,4,5,6,7) verified clean with exact quote matches and document identities confirmed (dates, document numbers, authorship all check out).
