Explanation: While all of the European powers in Africa in the 19th and early 20th century were varying degrees of exploitative and genocidal under the excuse of 'civilizing' Africans, the Belgians take the cake for sheer pointless fucking cruelty. King Leopold II and the 'Congo Free State' engaged in... truly horrific practices that beggar belief. Amputations, reprisal murders for not meeting quotas, casually exterminating literal millions of human beings.
It's one of the ugliest parts of an already quite ugly part of history.
