How did Belgian imperialism in Africa differ from British imperialism

The Belgian colonial Empire originated with the arrival of Belgium in the partition of Africa, where King Leopold II managed to obtain most of the region of the Congo. After the First World War, the Belgians obtained from Germany, through the Treaty of Versailles, the colony of Rwanda-Urundi. King Leopold II of Belgium established a private colony. The British Empire comprised colonies and other territories ruled by the United Kingdom. The climax of the empire occurred during the so-called imperial century through a series of phases of expansion with trade and colonization. The Empire increased the technology and the economic growth of the United Kingdom.
