The First Liberian Civil War (1989 to 1997) and Second Liberian Civil War (1999 to 2003) severely damaged many buildings and nearly all the infrastructure in the city, particularly during the siege of Monrovia. There were major battles between Samuel Doe's government forces and Prince Johnson's forces in 1990, and during the National Patriotic Front of Liberia's assault on the city in 1992. During the wars, many children and youths were forced to be involved in the fighting, and were deprived of any schooling, and afterwards, many of them were left homeless.
