16 university graduates, 600 priests and an explosive political situation

Hello to all of you ! Can you guess the country we are flying to ?  here is a clue to help you : I am an African country, and was personal and private possession of a European king. My abundant natural wealth encouraged my owner and his companies to undertake the brutal exploitation of my population, which diminished by half between 1880 and 1926, to the point that some historians refer to this period as a "forgotten holocaust". When I became independent on June 30, 1960, unlike other French and English colonies, I didnt have senior officials capable of running the independent country, since only 16 university graduates against 600 priests were trained by the former colonizer.

welcome to the origin of the current problems of the present day DRC, former Belgian Congo
