The civilian government of Mauritania was overthrown on 6 August 2008, in a military coup d'état led by General Mohamed Ould Abdel Aziz. On April 16, 2009, General Aziz resigned from the military to run for president in the July 19 elections, which he won. In Mauritania about 20% of the population live on less than US $1.25 per day.
The Emirate of Trarza was a precolonial state in what is today southwest Mauritania, which has survived as a traditional confederation of semi-nomadic peoples to the present day. Its name is shared with the modern Region of Trarza. The population, a mixture of Berber tribes, were later conquered by Hassaniya Arabic speakers from the north. Europeans called these people Moors/Maures, and thus have titled this group the Trarza Moors.
