The Magistrate Alliance quickly secured support in South Africa, especially in the Transvaal region inhabited by Dutch settlers. Using the duel fronts of southern Africa and Europe, the Magistrate quickly took out the vast majority of colonial forces on the continent, as well as the local armies. French forces fleeing the front in Europe managed to make it to their African territories, and held on there until the Magistrate decided to stablise its hold over its territories.
With a lack of regular colonial and local armed forces, and with the Magistrate taking no particular line of control, the area now known as the Central African Control Zone broke down into many lawless frontiers, mostly controlled by local warlords. In recent years, the Magistrate Alliance has begun to push back into the territory, establishing military outposts to claw back control of the surrounding lands.
p.s. sorry for my blatant colonialazy attitude in this timeline, what with the large space-filling C.A.C.Z. in the middle of the map,
lol, but it gets across the point I wanted to make
