Nubia's ancient cultural development was influenced by its geography. It is sometimes divided into Upper Nubia and Lower Nubia. Upper Nubia was where the ancient Kingdom of Napata (the Kush) was located. Lower Nubia has been called "the corridor to Africa", where there was contact and cultural exchange between Nubians, Egyptians, Greeks, Assyrians, Romans, and Arabs. Lower Nubia was also where the Kingdom of Meroe flourished. The languages spoken by modern Nubians are based on ancient Sudanic dialects. From north to south, they are: Kenuz, Fadicha (Matoki), Sukkot, Mahas, Danagla.
