In January 2012 a Tuareg rebellion began in Northern Mali, led by the National Movement for the Liberation of Azawad. In March, military officer Amadou Sanogo seized power in a coup d'état, citing Touré's failures in quelling the rebellion, and leading to sanctions and an embargo by the Economic Community of West African States. The MNLA quickly took control of the north, declaring independence as Azawad. However, Islamist groups including Ansar Dine and Al-Qaeda in the Islamic Maghreb (AQIM), who had helped the MNLA defeat the government, turned on the Tuareg and took control of the North with the goal of implementing sharia in Mali.
