The coup attempted sparked the Burundian Civil War, which lasted from 1993 to 2005, killing an estimated 300,000 people. The Arusha Accords ended 12 years of war and stopped decades of ethnic killings. The 2005 constitution provided guaranteed representation for both Hutu and Tutsi, and 2005 parliamentary elections that led to Pierre Nkurunziza, from the Hutu FDD, becoming president.
