Reminds me of the Domination series.
The world of The Domination diverges from our world at the time of the
American Revolutionary War, when the
Netherlands declares war on the
UK, resulting in the loss of its
Cape Colony to the British. After defeat in Revolutionary War, the
Loyalists who historically went to Canada are instead resettled in the new Crown Colony of Drakia (named after
Sir Francis Drake) in
South Africa, taking their slaves with them. Thousands of Hessian German mercenaries who fought on the Loyalist side are also given asylum there. The
Crown Colony of Drakia (later, the
Dominion of Draka) is an aggressive
militaristic slave-owning society, massively influenced by the inherent racist attitudes of these American slave owner settlers that are allowed to run unchecked, reinforced over the course of the late 18th and 19th century by 25,000
Icelanders fleeing their island after
1783-84 Volcanic devastation.
French royalists, 150,000 defeated
American Confederates and other
reactionary refugees. The much earlier Dutch Boer settlers are completely assimilated by these subsequent immigrants. The genealogical lineage of both the original Boer and Southern Loyalist settlers from the late 17th century and 1780s, respectively, is almost overwhelmingly Anglo-Saxon, Nordic, Germanic and Celtic although later immigrants are French Protestant Huguenots fleeing persecution from Roman Catholics, and then the aforementioned French aristocrats seeking sanctuary from the French Revolution. Although most Draka remain at least nominally Christian for several generations, by the 1960s, the practice of Christianity among them has declined to the point the few remaining Christian Citizens are subject to scrutiny by the Security Directorate and unofficially prevented from attaining officer ranks in the military. The Draka capital city is Archona, on the site of our own world's
Pretoria.
