The People of Sudan
The citizens of Sudan are called Sudanese. The word works both as a noun for the people and as an adjective for anything connected to the country, much like the word for many other nationalities.
A Country in North-East Africa
Sudan is a large country in north-eastern Africa, with its capital at Khartoum. It is one of the biggest countries on the African continent by land area. The River Nile runs through it, and the capital itself sits where two great branches of the river, the Blue Nile and the White Nile, meet.
A Name Meaning the Land of Black Peoples
The name Sudan comes from an Arabic phrase, bilad al-sudan, which means the land of the black peoples. Historically the term described a broad belt of Africa south of the Sahara Desert. Today the Sudanese people are made up of many different ethnic groups speaking a range of languages, though Arabic and English serve as the official languages of the country.
