Khartoum or Khartum is the capital of Sudan. With a population of 5,274,321, its metropolitan area is the largest in Sudan. Khartoum is located at the confluence of the White Nile, flowing north from Lake Victoria, and the Blue Nile, flowing west from Lake Tana in Ethiopia. The location where the two Niles meet is known as al-Mogran or al-Muqran. From there, the Nile continues to flow north towards Egypt and the Mediterranean Sea.
Divided by these two parts of the Nile, Khartoum is a tripartite metropolis with an estimated overall population of over five million people, consisting of Khartoum proper, and linked by bridges to Khartoum North and Omdurman to the west.
Khartoum was founded in 1821 as part of Ottoman Egypt, north of the ancient city of Soba. While the United Kingdom exerted power over Egypt, it left administration of the Sudan to it until Mahdist forces took over Khartoum. The British attempted to evacuate Anglo-Egyptian garrisons from Sudan but the Siege of Khartoum in 1884 resulted in the capture of the city by Mahdist forces and a massacre of the defending Anglo-Egyptian garrison.
