Answer:
Belgium colonized Congo.
Explanation:
In the late 19th century, King Leopold II of Belgium acquired control of the Congo territory at the Berlin Conference in 1885. He declared the land his personal property, known as the Congo Free State, and proceeded to exploit its resources and people through forced labor, atrocities and violence.
Under Leopold's rule, the Congolese people were subjected to brutal treatment, including mutilations, massacres, and enslavement for the extraction of rubber and ivory. Estimates suggest that millions of Congolese people died as a result of the harsh conditions imposed by the Belgian colonizers.
In 1908, due to international outcry and pressure, the Congo Free State was annexed by Belgium and became a Belgian colony known as the Belgian Congo. While conditions improved slightly under Belgian rule, the Congolese people continued to be exploited for their resources and forced to work under oppressive conditions.
Belgium maintained control over Congo until it gained independence in 1960. The legacy of Belgian colonialism in Congo continues to have lasting effects on the country's political, social, and economic development.
