After the Islamic Salvation Front (FIS) won the 1991 elections, and was then banned after the elections' cancellation by the military, the tensions between Islamists and the government erupted into open fighting, which lasted some 10 years in the course of which some 100,000 people were killed. However, some Islamist parties remained aboveground - notably the Movement of Society for Peace and Islamic Renaissance Movement - and were allowed by the government to contest later elections. In recent years, the Civil Harmony Act and Charter for Peace and National Reconciliation have been passed, providing an amnesty for most crimes committed in the course of the war.
