The new president had the staunch support of the United States because of his opposition to Communism; the US believed that his administration would serve as an effective counter to communist movements in Africa. A single-party system was established, and Mobutu declared himself head of state. He periodically held elections in which he was the only candidate. Although relative peace and stability were achieved, Mobutu's government was guilty of severe human rights violations, political repression, a cult of personality and corruption.
