Bouteflika is the longest-serving president of Algeria. During his years of presidency, Bouteflika has succeeded in ending a civil war that ran throughout the nineties and was one of the bloodiest civil unrests of the 20th century in the Muslim world. Peace was reached through a process of reconciliation and amnesty that was strongly supported by the Islamist and Nationalist belligerents. Following constitutional amendments, Bouteflika won his fourth term as president in April 2014 with 81% of the vote. Since suffering a stroke his physical health has deteriorated rapidly. In 2017, he ordered the government to reduce imports, curb spending and warned of the dangers of foreign debt. He made a call for reform in the banking sector as well as an increase in investment in renewable energy, specifically shale.
