I guess I will have to continue with this myself I guess?
I will talk about the Kanembu, the most important civ missing from Africa imo, a long lasting and very powerful empire based in central Africa that lasted 900 years.
Kanembu 
Cavalry and monk civilization
Town center techs -60% cost and research time
The Kanem-Bornu empire was formed at the beggining of the 8th century by a previously nomadic people, the Kanembu, around the region of lake Chad taking control over the Sao walled cities, thats why I thought a town center bonus would be accurate.
Castle age costs no gold, imperial age half gold cost
While most kingdoms in the Sahel had access to plenty of gold to mine, gold wasnt common in the surroundings of Lake Chad
Knights and monks +10 hit points at castle/imperial age
As a nomadic people in the sahel cavslry was integral to the Kanembu army. This bonus is more talking about the diferent Jihads the Kanembu started against the nearby peoples.
Team bonus:
Fishing ships +2 line of sight
While this bonus doesnt really synergyze well with the rest of the civ, the Kanembu were baded around Lake Chad and fished plenty on it. Either way open to better ideas

Cima historical background
Cima means “fief-holder” in kanuri. The Cima were warriors that after the conquests done by Dunama Dabalemi got their own lands to control, but still under the control of the Mai (or emperor). However, the Cima rised against the Mai, leading to the fall of Kanem and to make the ruling dynasty to move to Bornu.
They are also an skirmisher because the javelin throwing was an integral part of African warfare and while we already have a mounted skirmishers and imperial skirms we dont have an alternate version of the skirm yet.
Unique Techs
Imperial Reforms
Military units and monks created 33% faster
The peak of the power of the Kanem Bornu Empire arrived with the reign of Mai Idris Alooma, who reformated the empire, extended the borders of their territory and also made the empire into a center for muslim scholarship. Its basically castle age conscription but affecting siege and monks.
Cost: 150F 200W
Gambeson
Knights and light cavalry +30 hit points (2 minutes research time)
The padded armour was common beetwen the diferent kingdoms of the Sahel and gave a lot of protection against proyectiles. Sadly, Hauberk already exists, but I guess this is the next best thing, and also a nice way of buffing the light cav.
Cost: 900F 500G
Missing techs
- Barracks: eagle scout, champion
- Archery range: arbalest, heavy cavalry archer, parthian tactics
- Stable: hussar, paladin, battle elephant, steppe lancer
- Blacksmith: ring archer armour
- Siege workshop: heavy scorpion
- Monastery: /
- Dock: dry dock, fast fire ship
- Economy: gold shaft mining, two-man saw
- Castle: Conscription
- University: architecture
Something I dont feel very happy is that the civ only unique military advantages beyond faster working monasteries and siege workshops is just extra hit points on cavalry units and monks so its a bit one note but Im open to any new ideas to improve that by adding something else, I just wanted to use cavaliers with high hp somewhere tbh and not giving them some of the extra hp earlier felt like wasting a possible knight rush bonus.
