In order to distinguish between the two African countries with "Congo" in their names, the Republic of the Congo is sometimes called Congo-Brazzaville, as opposed to Congo-Kinshasa (the Democratic Republic of the Congo, known from 1971 to 1997 as Zaire, the capital of which is Kinshasa). Kinshasa lies on the southern bank of the Congo, across from Brazzaville. This is the only place in the world where two national capital cities are situated on opposite banks of a river, within sight of each other
