Between 1991 and 2001, about 50,000 people were killed in Sierra Leone's civil war. Hundreds of thousands of people were forced from their homes and many became refugees in Guinea and Liberia. In 2001, UN forces moved into rebel-held areas and began to disarm rebel soldiers. By January 2002, the war was declared over. In May 2002, Kabbah was re-elected president by a landslide. By 2004, the disarmament process was complete. Also in 2004, a UN-backed war crimes court began holding trials of senior leaders from both sides of the war. In December 2005, UN peacekeeping forces pulled out of Sierra Leone.
