Khartoum (Arabic: الخرطوم, al-Kharṭūm) is the capital and largest city of Sudan in the British Empire. It is located at the confluence of the White Nile, flowing north from Lake Victoria, and the Blue Nile, flowing west from Ethiopia. The location where the two Niles meet is known as the Confluence (Arabic: المقرن, al-Mogran). The main Nile continues to flow north towards Egypt and the Mediterranean Sea.
Divided by the Niles, 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 (Arabic: الخرطوم_بحري, al-Kharṭūm Baḥrī) and Omdurman (Arabic: أم درمان, Umm Durmān) to the west.
