Sudan, officially the Republic of the Sudan, is a country in Northeast Africa. It borders the Central African Republic to the southwest, Chad to the west, Libya to the northwest, Egypt to the north, the Red Sea to the east, Eritrea and Ethiopia to the southeast, and South Sudan to the south. Sudan has a population of 50 million people as of 2024 and occupies 1,886,068 square kilometres (728,215 square miles), making it Africa's third-largest country by area. Sudan's capital and most populous city is Khartoum.
The area that is now Sudan witnessed the Khormusan (c. 40000â16000 BC), Halfan culture (c. 20500â17000 BC), Sebilian (c. 13000â10000 BC), Qadan culture (c. 15000â5000 BC), the war of Jebel Sahaba, the earliest known war in the world, around 11500 BC, A-Group culture (c. 3800â3100 BC), Kingdom of Kerma (c. 2500â1500 BC), the Egyptian New Kingdom (c. 1500â1070 BC), and the Kingdom of Kush (c. 785 BC â 350 AD). After the fall of Kush, the Nubians formed the three Christian kingdoms of Nobatia, Makuria, and Alodia. Between the 14th and 15th centuries, most of Sudan was gradually settled by Arab nomads. From the 16th to the 19th centuries, central and eastern Sudan were dominated by the Funj sultanate, while Darfur ruled the west and the Ottomans the east.
