The King Leopold II that you are alluding to in this question was the King of Belgium. He reigned from 1865 until his demise in 1909. He is associated with the Congo since he procured that area as an individual holding and abused it in a way that was unpleasantly merciless notwithstanding for that day and age.
Leopold had faith in the requirement for provinces. In this manner, he attempted to get different territories of the world for Belgium. Notwithstanding, he didn't do this transparently. Rather, he attempted different approaches to hide what he was doing. By the mid-1880s, he could get the universal group to dole out the Congo to an organization that he claimed.
