Deutsch-Mittelafrika

Foundation
Deutsch-Mittelafrika as a sovereign polity first came into existence after the Weltkrieg was ended by the Peace With Honour and numerous capitulation treaties by the nations the Central Powers were able to defeat. In the aftermath of the WK, Germany was given a large portion of subsaharan Arikan land by France, who retained their north African holdings (mostly). This land was eventually organized into the Freistaat.

First Expansion
The First Expansion of Deutsch-Mittelafrika occurred during the Syndicalist Revolutions of the 1920s. When the British Government was being defeated by the Syndicalist forces of the recently-proclaimed "Union of Britain", the Germans could not afford direct intervention but simultaneously couldn't afford the colonies to fall to Socialism, and so as the British Gov't fled to Canada, the German Empire seized all of their African colonial holdings except Sierra Leone, which was seized by their ally National France, and Egypt, which they'd de jure lost to the Ottomans at the Peace With Honour. Mittelafrika was now engorged by the amount of colonies it had absorbed and its political system soon became a bloated mess as a result.
