1989 Philippine Coup Attempt

Also known as: December 1989 coup attempt · 1989 coup d'état attempt · December 1989 rebellion

Definition

The 1989 Philippine coup attempt (December 1–9, 1989) was the bloodiest and most serious of the coup attempts mounted against the government of President Corazon Aquino — the culminating mutiny of the series this wiki’s entry on the Armed Forces of the Philippines records for the years 1986–1990. It was staged by the Reform the Armed Forces Movement (RAM), led by Lieutenant Colonel Gregorio “Gringo” Honasan — who had also led the August 1987 attempt — with Generals Edgardo Abenina and Jose Ma. Zumel and Captain Proceso Maligalig, joined by soldiers loyal to the deposed president Ferdinand Marcos, whose fall in the People Power Revolution that followed the disputed contest treated in this wiki’s entry on the 1986 snap presidential election had opened the decade’s crisis of legitimacy. Rebels seized Villamor Air Base, Fort Bonifacio, Sangley Point, Mactan Air Base in Cebu, and portions of Camp Aguinaldo, bombarded Malacañang, Camp Crame, and Camp Aguinaldo, closed the airport runway, and occupied twenty-two high-rises in the Makati business district. (Wikipedia)

The government crushed the attempt by December 9, 1989, at an official cost of 99 dead, including 50 civilians, and 570 wounded, with business leaders estimating the damage at US$1.5 billion. The decisive outside intervention was American: under Operation Classic Resolve, F-4 Phantom II fighters flew from Clark Air Base — with the carriers USS Midway and USS Enterprise offshore — their pilots authorized to shoot down any rebel aircraft that attempted takeoff, while Washington declined the requested air strikes. Vice President Salvador Laurel openly allied himself with the plotters and called for Aquino’s resignation. The aftermath produced the Davide Commission and, in time, amnesty.

Examples and Analogies

A coup in five acts: the seizure of air bases on December 1, with T-28 aircraft dive-bombing Malacañang; the bombardment of the palace and camps from Sangley; the government’s recovery of the bases by December 3; the rebel holdout in Makati’s high-rises until December 7; the final surrender at Mactan on December 9. (Wikipedia)
The economy as battlefield: by occupying the Makati high-rises and closing the airport runway, the mutineers fought where the government was most vulnerable; business leaders put the cost at US$1.5 billion. (Wikipedia)

Usage Scenarios

1. Studying Civil–Military Relations

The attempt is the standard Philippine case study of a democratizing government’s contest with its own armed forces: its failure closed the era in which mutiny could plausibly be presented as a substitute for elections. (Wikipedia)

2. Examining Alliance Behavior

Operation Classic Resolve is studied for what it gave and what it withheld — air cover that grounded rebel aviation, alongside a refused request for air strikes on grounds of political risk. (Wikipedia)

3. Institutional Reform After Crisis

The commission created by Republic Act No. 6832 (January 5, 1990), chaired by Hilario Davide Jr., produced the era’s reform program; its civilian-police recommendation was realized under Republic Act No. 6975, and the coup era’s equipment and professionalism gaps found their answer in the AFP Modernization Act (Republic Act No. 7898, February 23, 1995) treated in this wiki’s entry on that law. (LawPhil — RA 6832, LawPhil — RA 7898)

4. Amnesty and Reconciliation

The prosecutions dissolved into amnesty: Proclamation No. 347 (1994) covered crimes committed in pursuit of political beliefs, another covered RAM under the 1995 peace agreement, and Proclamation No. 724 (May 17, 1996) extended the window to offenses on or before June 1, 1995. (LawPhil — Proclamation No. 724)

Strategies

Bases before barracks: the rebels’ first objective was air power — Villamor, Sangley, Mactan — and the recovery of the bases by December 3 decided the attempt. (Wikipedia)
Calibrated foreign signaling: the American contribution was presence rather than firepower — fighters over Manila and carriers offshore, the requested strikes refused — protecting the government without making the United States the combatant. (Wikipedia)
Inquiry as closure: the government answered the coup not only with guns but with Republic Act No. 6832, converting crisis into record and reform agenda. (LawPhil — RA 6832)
Amnesty as terminus: with RAM reintegrated under the peace agreements and amnesties culminating in Proclamation No. 724, the state traded prosecution for reunification of the officer corps. (LawPhil — Proclamation No. 724)

Security and Safety Measures

Air denial over the capital: under Operation Classic Resolve, US pilots were authorized to buzz rebel aircraft, fire ahead of any attempting takeoff, and shoot them down if they did; US Marines guarded the American embassy during the fighting. (Wikipedia)
For researchers: the standard figures — 99 dead and 570 wounded, the US$1.5 billion estimate — were produced amid the crisis they measure; treat them as order of magnitude, not precise accounting. (Wikipedia)

Historical Context

The attempt grew from the legitimacy crisis opened by the disputed 1986 snap presidential election and the People Power Revolution that ended Marcos’s rule, narrated in this wiki’s entries on the 1986 snap presidential election and Corazon Aquino. RAM, whose August 1987 attempt led by Honasan had nearly succeeded, joined with Marcos loyalists in a larger, better-financed design: on December 1, 1989 rebel units seized Villamor, Sangley, Mactan, Fort Bonifacio, and parts of Camp Aguinaldo, dive-bombed Malacañang with T-28s, bombarded the palace and camps from Sangley, and shut the airport runway before occupying the Makati high-rises. Vice President Laurel’s call for Aquino’s resignation marked the political as well as military front. (Wikipedia)

Government forces retook the bases by December 3; the Makati occupation ended December 7; Mactan surrendered December 9. Honasan fled, other plotters were arrested, and some were later amnestied; smaller mutinies followed in 1990. The reckoning shaped institutions: Republic Act No. 6832 created the Davide Commission; Congress later answered the military’s gaps with the AFP Modernization Act; and the amnesties of 1994–1996, culminating in Proclamation No. 724, ended the prosecutions.

Challenges and Controversies

Counting the Coups

Sources tally the Aquino-era attempts differently — six, seven, or nine depending on the threshold applied to minor mutinies — and this wiki’s entry on Corazon Aquino follows the count of seven. All agree on the ranking: December 1989 was the largest, best-financed, and by far the bloodiest. (Wikipedia)

The American Role

Operation Classic Resolve reopened the debate over the US bases and alliance politics: defenders credit American air cover with saving an elected government at its most vulnerable; critics note that the intervention decided a Filipino constitutional crisis; and Washington itself refused the requested air strikes. (Wikipedia)

Amnesty Versus Accountability

The plotters’ reintegration — amnesties culminating in Proclamation No. 724, with Honasan himself fleeing abroad — remains contested: reconcilers credit the settlement with reunifying the officer corps and ending the coup cycle; critics answer that it turned a mutiny of ninety-nine deaths into negotiated forgetfulness. (Wikipedia, LawPhil — Proclamation No. 724)

The Civilian-Police Answer

The Davide Commission’s structural lesson — that a militarized police had been party to the era’s instability — produced the abolition of the Constabulary’s dual structure under Republic Act No. 6975 and the creation of the civilian Philippine National Police, examined in this wiki’s entries on the Philippine Constabulary and the Integrated National Police.
