On April 15, 1974 Lieutenant Colonel Seyni Kountche led a largely bloodless military coup in Niger that overthrew President Hamani Diori, ending the fourteen-year rule of the country's first postcolonial leader amid the devastation of the Sahel drought and famine. Diori's single-party PPN government had grown deeply unpopular as the 1968 to 1974 drought ravaged the country, with widespread anger over allegations that ministers were misappropriating and hoarding food aid while people starved; Diori had also concentrated power, limiting cabinet posts to fellow Djerma, relatives, and friends, and taking the foreign and defense portfolios himself. The army resented being used for tax collection and was further angered by a recently signed defense treaty with Libya.
The coup began at 1 a.m. on April 15; nearly all units immediately joined the coup leaders.
The only resistance came from Diori's all-Tuareg Republican Guard under orders from his wife Aissa Diori, who together with several guardsmen was killed at the presidential palace after dawn. Diori and other PPN politicians were arrested. Kountche formed a Supreme Military Council and ruled until his death in 1987.

Sources
On 15 April 1974 Lieutenant-Colonel Seyni Kountche led a military coup that ended the fourteen-year rule of Diori, beginning at 1 AM with all but a handful of units quickly declaring for the coup leaders; the personal guard of President Diori, the all-Tuareg Republican Guard, was the only unit to resist, under the orders of Diori's wife Aissa Diori, and she and a small number of Guardsmen were killed at the presidential palace after dawn.
The Sahel drought of 1968 to 1972 had aggravated tensions in the single-party PPN government, and widespread civil disorder followed allegations that some government ministers were misappropriating stocks of food aid and accused President Diori of consolidating power by limiting cabinet appointments to fellow Djerma, family, and friends and declaring himself minister of foreign and defense affairs.
Diori, the President of the National Assembly Boubou Hama, and several other PPN politicians in Niamey were arrested in the operation, and Diori was imprisoned until 1984 and remained under house arrest, while a Supreme Military Council was established on 17 April 1974 with Kountche as president, mandated to distribute food aid fairly and restore morality to public life.
Besides the drought, the army resented being used for tax collection and other political activities, and shortly before the coup the Nigerien government signed a mutual defense treaty with Libya which enraged army members; according to Kountche, over 3,000 tons of grain were held in a warehouse waiting for prices to rise while the president did nothing.
Fate coding: Diori was arrested and imprisoned (held to 1980, then under house arrest until 1984), matching the dataset's house-arrest-and-jailed fate; he himself was not killed. Killings note: the coup was largely bloodless, but the president's wife Aissa Diori and several Republican Guardsmen were killed resisting at the palace, which is cited and attributed rather than editorialized. Context: the Sahel drought and famine, and anger over hoarded and misappropriated food aid, were the central drivers; the new Supreme Military Council's stated first mandate was fair food-aid distribution. Arc forward: Kountche ruled until his death in 1987; Diori's fall ended the first postcolonial government of Niger.
