Mauritania, 2008 — military coup

Mauritania (MRT)West Africa, AfricaAugust 6, 2008

Event Summary

On 6 August 2008 a military coup in Mauritania ousted President Sidi Ould Cheikh Abdallahi, the country's first democratically elected head of state, only about sixteen months after he took office in the 2007 transition. The coup came within hours of Abdallahi issuing a decree that fired the four top military officers, including General Mohamed Ould Abdel Aziz, commander of the presidential guard, who had been accused of siding with lawmakers against the president. Troops of the presidential security battalion, led by Abdel Aziz, seized the state media and arrested Abdallahi along with Prime Minister Yahya Ould Ahmed el-Waghef and the interior minister.

The junta, calling itself a High Council of State with Abdel Aziz at its head, immediately annulled the president's dismissal decree, called Abdallahi the former president, and promised new elections. Abdallahi was detained at the presidential palace compound. The coup followed months of political conflict, including a parliamentary revolt and disputes over Abdallahi's outreach to Islamists and his appointment of ministers linked to the old Taya government.

It was condemned by the United States, the European Union, and the African Union, which demanded his release and suspended Mauritania. Abdel Aziz went on to win a 2009 election after stepping down to run.

The 2008 Mauritanian coup took place on 6 August when President Sidi Ould Cheikh Abdallahi was ousted by the armed forces, led by a group of high ranking generals he had dismissed from office earlier that day, and General Mohamed Ould Abdel Aziz, a leading figure in the 2005 coup, headed the new military State Council that called Abdallahi the former president.

Editorial Note

Coded fate arrested or jailed is verified: Abdallahi was detained at the palace compound. Coded as a military coup on 08-06, matching the sources. This is the second of the two paired Mauritania records; it ties directly to the 2005-08-03 coup (record 43508032005). The link is sharp: Abdel Aziz, who led this 2008 coup, had helped lead the 2005 coup, and the president he overthrew here (Abdallahi) was the civilian the 2005 junta's transition brought to power. Abdel Aziz stepped down to run and won the 2009 election, becoming president himself.
