Quite a far cry of how life is there now... Belgium was going to transition away and give the Congo it's independence, but the Congolese people had no patience for that and began getting violent. This led to a premature departure with a weak and new Congolese government. What followed was civil war and complete destruction of all infrastructure and means of living free of poverty... A sad story for sure. You can't blame the Congolese people for wanting their independence and certainly the Belgian people didn't treat them as equals (segregation wasn't the law, but it was a common social practice). I sure wish things could have worked out better. Though the Congolese people didn't have autonomy, quality of life was far better.
