How did King Leopold treat Congo's workers, and does that still shape its economy?

Research question: What specific economic structures and labor practices did King Leopold's administration implement in the Congo Free State, and how did these create the foundation for the modern extraction-based economy?

The records show that Leopold's concession companies were given powers normally held by governments, including a monopoly over violence and the power to tax, with resource extraction as their main purpose ¹¹. Concessionaires policed their own territories and collected taxes in rubber, and the crown's profits came almost entirely from rubber while minerals were largely untouched ³⁵⁶. Each concession post used one or two European agents to count adult men for forced rubber collection ¹², and the Force publique took hostages, mostly women, to compel husbands to meet quotas ¹⁸. Leopold's template prioritized huge profits over building a self-sustaining Congolese economy, which is the closest the facts come to linking this past to the modern extraction-based economy ¹. The newest fact is a 2026 study, which concerns cobalt mining and explicitly does not describe Leopold's structures or labor practices ¹⁴, so the modern connection is only partly supported.
