Great Sudan

The regions of Ancient and Medieval Nubia consists of South Egypt and the Nilotic part of Sudan. Many people are not familiar with the countries that existed in this region, but Ancient and Medieval Nubia was actually very similar to Egypt, and lasted there for over 1500 years after Egypt has collapsed.

Over time, however, the Nubians became more and more arabized, and in 1504 the last true Nubian state known as Alodia, was conquered by the Funj, who were muslims.

Yet, what if, in an alternate timeline, the fall of Nubia was prevented and the Nubian civilization would stay until the present? We will see in this timeline. Note that even through Alodia fell in 1504, this timeline starts in 1320 because by 1504 Alodia was so weak it simply couldn't resist the Funj threat.

Alodia
The only remaining true Nubian state, and the last Christian state in Nubia, Alodia is extremely endangered in 1320 by both the Mamluks in the north, and the Funj tribes to the south. Will Alodia manage to conquer it's enemies, or will it fall to the muslims just like in our timeline?

Mamluk Sultanate (Cairo)
The Mamluks are the biggest threat to both Alodia and Ethiopia, as they recently conquered Makuria, an another Nubian state in 1312. They own lands from Central Nubia to Syria to Libya, and are able to attack and destroy Alodia and possibly even Ethiopia any time possible.

Ethiopia (Abyssinia)
The most developed country in Africa, Ethiopia is unique in it's ways of culture and religion. They follow Coptic Christianity as their official religion, and are good friends with Alodia.

Bunyoro-Kitara Kingdom
Located in northern Uganda, the Bunyoro-Kitara Kingdom was one of the oldest states in Africa, being founded around the year 920. Until the rise of the Rwanda Empire, the Bunyoro-Kitara was the strongest and wealthiest state in Tropical Africa.
