Under the corvée system, Congolese were forced to work on a variety of projects, including the construction of roads, railways, and other infrastructure projects. They were also forced to work in the mines, where they were subjected to dangerous and unhealthy working conditions.
The corvée system was extremely exploitative and oppressive, and it resulted in the deaths of millions of Congolese. The system also contributed to the widespread economic and social problems in the Congo Free State.
The international community eventually condemned the corvée system and forced Belgium to abolish it in 1908. However, the legacy of the system continued to affect the Congo for decades to come.
