Commonwealth of Centaurus

The Commonwealth of Centaurus is a postseditio human nation that controls a significant portion of the core of human space, including Alpha Centauri, Proxima Centauri, Tau Ceti, and Sol. Established on Terra Nova in 2271, it seized the political vacuum left by the United Colonies in order to hegemonise most of the Core Worlds.

In the aftermath of the Colonial Revolution, the Commonwealth grew to be one of the dominant political and military powers in human space, leading the charge against Colonial remnants during the Continuation Wars and holding many smaller states under its sphere of influence. Its recent history has been characterised by its struggle with the Sulycan Federation for control of the Core Worlds.

Anteseditio period
Prior to the Revolution, talk of independence for Alpha or Proxima Centauri was little more than a fringe ideology with few adherents. Indeed, many of the United Colonies' strongest supporters were found in these systems, even during the Human-Akranian War.

In that conflict's aftermath, however, a large portion of the UC's heavy taxation was placed on the wealthy Core Worlds, outraging many. Furthermore, the poor handling of refugees that had fled their homes during the war, as well as the cutting of several major social programs in order to fund military reconstruction efforts frustrated many more. All these, along with general agitation following the loss of the war, provided the needed spark for revolution.

Government
The Commonwealth of Centaurus is a parliamentary republic with

Political divisions
The Commonwealth is organised in a federal system comprised of 25 distinct republics, along with six protectorates. The Commonwealth also observes tribal sovereignty for the indigenous nations of Abramsia, who are given dual citizenship with the Commonwealth and their respective tribe. No constituent member or protectorate of the Commonwealth is permitted to engage in foreign relations, declare war, or create their own currency.
