Sudan (region)
The Sudan is the name given to a geographic region to the south of the Sahara, stretching from Western to Eastern Africa. The name derives from the Arabic bilād as-sūdān (بلاد السودان) or "land of the Blacks" (an expression denoting West and Central Africa). The phrase "The Sudan" is also used to refer specifically to the modern-day country of Sudan, the western part of which forms part of the larger region, and from which South Sudan gained its independence in 2011.
