This document provides a brief history of the Congo, beginning with pre-colonial tribes and communities in the Congo basin from 500 BCE to 600 CE. It then discusses the Congo Free State under King Leopold II of Belgium from 1885 to 1908, noting the human rights abuses and pressure from outside observers that led to reforms. Finally, it covers the Rwandan genocide of 1994 and its impact on the Democratic Republic of the Congo, including the formation of Hutu and Tutsi refugee camps in the DRC that exacerbated conflict.
