Sierra Leone: At a glance

Sierra Leone is a sovereign country in Africa, with a total land area of approximately 71,620 sq km. Democracy is slowly being reestablished after the civil war from 1991 to 2002 that resulted in tens of thousands of deaths and the displacement of more than 2 million people (about a third of the population). The military, which took over full responsibility for security following the departure of UN peacekeepers at the end of 2005, is increasingly developing as a guarantor of the country's stability. The armed forces remained on the sideline during the 2007 and 2012 national elections, and over the past year have deployed over 850 peacekeepers in the African Union Mission in Somalia (AMISOM). As of January 2014, Sierra Leone also fielded 122 staff for five UN peacekeeping missions. In March 2014, the closure of the UN Integrated Peacebuilding Office in Sierra Leone (UNIPSIL) marked the end of more than 15 years of peacekeeping and political operations in Sierra Leone. The government's priorities include furthering development, creating jobs, and stamping out endemic corruption.
