Negroland

This area comprised at least the western part of the region called Sudan (not to be confused with the modern country).

[3] Some of the greatest states of those considered part of Negroland were the Bornu Empire and the Sokoto Caliphate.

The name "Sahara" is derived from the Arabic word for "desert" in the feminine irregular form, the singular ṣaḥra' (صحراء /ˈsˤaħra/), plural ṣaḥārā (صَحَارَى /ˈsˤaħaːraː/[4][5][6][7]), ṣaḥār (صَحَار), ṣaḥrāwāt (صَحْارَاوَات), ṣaḥāriy (صَحَارِي).

"Guinea", not to be confused with the modern country, then referred to the south-facing coast of West Africa and the land stretching upriver from there.

"Negroland" was the territory to the north of this, along the east–west axis of the Niger River, and the west-facing coast.
