Leopold II was the second King of the Belgians, ruling for a very long time, from 1865 to 1909. He is famously known as the "Builder King" in Belgium because he commissioned many impressive buildings and public projects there. However, he was also the sole owner of a large territory in Africa called the Congo Free State.
He used explorer Henry Morton Stanley to help him claim this vast region, and other European nations officially agreed to his ownership at the Berlin Conference. Leopold never visited the Congo himself but managed it for his own benefit, getting rich from valuable resources like ivory and rubber. He forced the local people to work under extremely harsh conditions to collect these resources. His administration in the Congo was terribly brutal, involving forced labor, torture, and widespread violence. It was common for people, including children, to have their hands cut off if they didn't meet their rubber quotas. These terrible actions led to a massive loss of life, with estimates suggesting millions of Congolese people died due to violence, famine, and disease during his rule. Many people around the world condemned his regime for these widespread human rights abuses.
Back home, Leopold's reign also saw significant changes in Belgium, like the introduction of universal male voting and new laws protecting workers. He was a complex figure, remembered for both his grand construction projects in Belgium and the immense suffering he caused in the Congo. His impact on both Belgium and the Congo was profound and long-lasting.
