How did King Leopold's rule shape Congo's borders and how it earned money?
Research question: How did King Leopold's rule of the Congo Free State shape the country's borders and its extraction-based economy?
The records show that the Congo's borders were set at the 1884-1885 Berlin Conference without regard to ethnic, linguistic, or cultural integrity 3, and that the 1964 uti possidetis principle legally preserved those colonial borders 4. Leopold secured recognition of his claim to the territory at that conference, even though it was his personal property 10. The extraction economy rested on forced labour, as the local population was made to harvest rubber for the Royal Domain or private companies to meet demand from the global tire market 14, and the commission of inquiry treated forced rubber labour as central to that economy 11. Mineral wealth such as copper, gold and diamonds began to be discovered at the end of the 19th century, adding to the extraction economy 18. The facts only partly answer the question, since they show the conference fixed the borders but do not directly tie Leopold's rule to their shape 310.
