The Revolutionary United Front, with support from the special forces of Charles Taylor's National Patriotic Front of Liberia, invades Sierra Leone in an attempt to overthrow Joseph Saidu Momoh, sparking the 11-year Sierra Leone Civil War.

The Revolutionary United Front (RUF) was a rebel group that fought a failed eleven-year war in Sierra Leone, beginning in 1991 and ending in 2002. It later transformed into a political party, which still exists today. The three most senior surviving leaders, Issa Sesay, Morris Kallon, and Augustine Gbao, were convicted in February 2009 of war crimes and crimes against humanity.

Charles McArthur Ghankay Taylor is a Liberian former politician and convicted war criminal who served as the 22nd president of Liberia from 2 August 1997 until his resignation on 11 August 2003 as a result of the Second Liberian Civil War and growing international pressure.

The National Patriotic Front of Liberia (NPFL) was a Liberian rebel group that initiated and participated in the First Liberian Civil War from 24 December 1989 – 2 August 1997. The NPFL emerged out of rising ethnic tensions and civil unrest due to the Liberian government that was characterized by totalitarianism, corruption, and favoritism towards ethnic Krahns. The NPFL invaded Liberia through Ivory Coast’s border with Nimba County in Liberia under the direction of Charles Taylor, a former Liberian politician and guerrilla leader who served as the 22nd president of Liberia from 2 August 1997 until his resignation on 11 August 2003.
