Until 1979, Liberia's economy was among the more developed and fastest-growing in Sub-Saharan Africa, but after the 1980 coup d'état, it declined, and the civil war destroyed much of Liberia's economy and infrastructure, especially the infrastructure in and around the nation's capital, Monrovia. The war also caused a brain drain and the loss of capital, as the civil war involved overthrowing the Americo-Liberian minority that ruled the country. Some have returned since 1997, but many have not.
