Abdou Diouf was president between 1981 and 2000. He encouraged broader political participation, reduced government involvement in the economy, and widened Senegal's diplomatic engagements, particularly with other developing nations. Domestic politics on occasion spilled over into street violence, border tensions, and a violent separatist movement in the southern region of the Casamance. Nevertheless, Senegal's commitment to democracy and human rights strengthened. Abdou Diouf served four terms as president.
