On April 12, 1980 a group of enlisted soldiers led by Master Sergeant Samuel Doe stormed the Executive Mansion in Monrovia and killed President William Tolbert, ending 133 years of Americo-Liberian political dominance and bringing the first indigenous Liberian to power. Liberia had been ruled since its 19th-century founding by the Americo-Liberian elite, descendants of freed American slaves, through the True Whig Party, which governed as an effective one-party state while the indigenous majority remained largely excluded. Economic strain, the 1979 Rice Riots, and repression had weakened Tolbert's government.
In the early hours of April 12, 1980, 17 non-commissioned officers and soldiers of the Armed Forces of Liberia, all indigenous Liberians, launched a violent coup, entered the mansion, and killed Tolbert; his body was dumped in a mass grave with other victims. Doe established the People's Redemption Council and ruled through the 1980s. Ten days later, 13 officials of his government were publicly executed.

The 1980 Liberian coup happened on April 12, 1980, when President William Tolbert of Liberia was overthrown and murdered in a violent coup staged by an indigenous Liberian faction of the Armed Forces of Liberia under the command of Master Sergeant Samuel Doe.
In the early hours of April 12, 1980, 17 non-commissioned officers and soldiers of the AFL led by Master Sergeant Samuel Doe launched a violent coup, all the conspirators being indigenous Liberians while Tolbert belonged to the Americo-Liberians, and the group entered the Executive Mansion and killed Tolbert, whose body was dumped into a mass grave together with 27 other victims of the coup.
Doe was a master sergeant in the Armed Forces of Liberia when he staged the violent 1980 coup that overthrew President Tolbert and the True Whig Party, becoming the first indigenous leader of Liberia and ending 133 years of Americo-Liberian rule, after which he suspended the constitution and established the People's Redemption Council.
In April 1980 Doe led an attack by a group of Krahn soldiers on the Liberian executive mansion, killing President William R. Tolbert, and later 13 prominent Tolbert associates were summarily tried and executed.

Editorial Note
Killings protocol applied: the deposed president Tolbert was killed in the assault on the Executive Mansion; the killing is cited and attributed, and sources note his body was dumped in a mass grave with more than two dozen other victims of the coup. Fate coding: killed, matching the dataset. Closely related separate event flagged: about ten days later, on April 22, 1980, thirteen senior officials of Tolbert's government were publicly executed by firing squad on a Monrovia beach after summary trials without legal representation; this mass execution is a distinct, closely related event, recorded here as flagged aftermath rather than as the fate of the April 12 coup itself. Conflicting accounts recorded: sources differ on where and by whom Tolbert was killed (one account has him shot sleeping in his office, another in the mansion; the soldier named as the killer is variously reported), and these discrepancies are recorded rather than resolved. Historical weight: this ended 133 years of Americo-Liberian True Whig Party dominance and brought the first indigenous head of state. Arc forward: Doe himself was captured, tortured, and killed in 1990 during the First Liberian Civil War, a separate later event.
