Republic of the Congo (Léopoldville)
The Republic of the Congo () was a sovereign state in Central Africa that was created with the independence of the Belgian Congo in 1960. From 1960 to 1966, the country was often known as "Congo-Léopoldville" (after its capital) in order to distinguish it from its north-western neighbour, also called the Republic of the Congo or Congo-Brazzaville. With the renaming of Léopoldville as Kinshasa on 1 June 1966, it was known as "Congo-Kinshasa" until 1971.
Lubumbashi
Lubumbashi (former names: (French) and (Dutch)) in the southeastern part of Democratic Republic of the Congo is the second-largest city in the country, the largest being the capital, Kinshasa. Lubumbashi is the mining capital of the Democratic Republic of the Congo, acting as a hub for many of the country's biggest mining companies. The copper-mining city serves as the capital of the relatively prosperous Haut-Katanga Province and is near the border with Zambia. Population estimates vary widely but average around 1.5 million.
