Guatemala, 1988 — military coup attempt

Guatemala (GTM)Central America, AmericasMay 11, 1988

Event Summary

The dataset records an attempted military coup in Guatemala on 11 May 1988, the first of two coup attempts against President Vinicio Cerezo, the Christian Democrat who in 1986 had become the country's first elected civilian president in decades, ending a long era of brutal military rule. Cerezo governed under the shadow of a still powerful army that retained enormous autonomy and continued to wage a savage counterinsurgency, and his fragile democratic experiment was resented by hardline officers opposed to any dilution of military prerogatives or to negotiations with the leftist insurgency. On 11 May 1988 a faction of the armed forces mounted a coup attempt against Cerezo, which was suppressed with the support of loyalist commanders.

Cerezo survived this and a second attempt in May 1989, managing against considerable odds to complete his term and hand power to an elected successor in 1991, a milestone in Guatemala's slow and violent transition from military dominance, though the army retained decisive influence and the civil war ground on until peace accords in 1996.

Editorial Note

Date match to the 11 May 1988 first coup attempt against Cerezo. Dataset codes it a military coup with leader unharmed, accurate. Verified via the coups list and Cerezo biography, though fine detail on the 11 May action is lightly sourced this session. First Guatemala record in the dataset run to reach this era.
