The Congo Free state was more of an enterprise set up by King Leopold from Belgium. This was over 100 years ago when Africa was being colonized by Germany, France, Italy, Belgium, basically all of Europe wanted a piece. Abundance of resources, low population compared to other continents, and of course it's inability to defend itself against invading Europeans. All of that made it a free for all for colonizing and exploitation. (sorry to say). King Leopold then got a wild hair up his ass and said, "I want to make my very own private company to reap the benefits of a high demand product at the time/rubber" and in deed he did! And what better way to abuse his power as king of a powerful European nation than take a colony in Africa (Congo) and make it into his personal investment. It wasn't even for the benefit of the Belgium economy, which is even more shocking. Even more profitable, every hired worker who brought back a basket of severed limbs of locals who caused trouble were given a bonus in their "compensation plan".
Now, who cannot say that is gross form of capitalist abuse?
fast forward to 100 years later, nations like DR Congo, Republic of Congo, Rwanda, etc.. all deeply scarred by the effects of what I just described.
sorry, that was a bit long I guess.
