Premise: The Sierra Leone Civil War (1991–2002) began on 23 March 1991 when the Revolutionary United Front (RUF), with support from the special forces of Charles Taylor’s National Patriotic Front of Liberia (NPFL), intervened in Sierra Leone in an attempt to overthrow the Joseph Momoh government. The resulting civil war lasted 11 years, enveloped the country, and left over 50,000 dead.
Hypothesis: Many other countries got involved in the Sierra Leone Civil War.
