In Archaic times, the Spinward Confederacy formed, splintering from the Core Commonwealth. A group of disenfranchised rebels felt that the Commonwealth was too huge and cold to effectively represent its planets and people. They felt that the Commonwealth was too concerned with military and trade and not focusing on improving lives through making necessities like healthcare, food, and technology available to all. The Commonwealth would not rally its resources against obviously cruel and primitive races like the Makkuth, nor would it force Empirical members like the Ourii to adopt democratic systems of representation. The rebels gathered their resources on the new Commonwealth colony of Silver, renaming it Garrison to represent its determination to succeed and to hold out against the assault of apathy and indifference.

The Commonwealth initially failed to respond to the separatist activity, thinking it was a minor inconvenience on the fringes of the empire. The hardworking and highly vocal colonists on Garrison would quickly recruit the established world of Jorum to succeed from the Commonwealth and join the newly named Spinward Confederacy. There followed a brief period of consolidation between the two worlds, which also featured considerable tension and some limited armed conflict with the Commonwealth. The conflict would scare and dishearten many Commonwealth members, in particular the world of Hadjel, which would outright switch sides and stand up for the fledgling Confederacy. In the face of internal pressure, the Commonwealth was forced to let its worlds go, though a bitter taste remained.

The Confederacy would enter a period of slow colonial growth, using the resources of its more mature worlds to settle and build up worlds like the colony and military base on Jezanne. There would be many trade, political, and armed disputes between the Confederacy and the Commonwealth over the years, leading to each refusing to trade with the others. This served only to isolate members from each empire who had historically traded with each other. They banded together on the planetary level to form the UTP and demand the right to trade independently with each other without interference from either empire.

The Spinward Confederacy still begrudges the Core Commonwealth and stale relations have occasionally erupted into conflict. While neither government is happy about it, individual worlds from the two empires trade freely under the Universal Trade Pact.

Cultural
The Spinward Confederacy is a predominantly human separatist alliance, whose worlds join voluntarily or are settled by the central government. "Soft aliens" who are humanoid are tolerated but any race resembling lizards, bugs, beasts and squid are generally considered sub-human and inferior.

The original intention of the Spinward Confederacy was to form a more socially more aggressive and progressive alliance of worlds focused on people before business. Its biggest problem is that its member worlds tend to disagree on everything from policy to  process. The Confederacy, though now a relatively mature government, never really got over the initial growing pains of empire. It is mired in the problems with strong central leadership. It spends more time administering and making decisions than redistributing wealth.

The Confederacy is run from a number of key positions. Every five years, a President and Vice President are individually elected through popular vote. The President is primarily an internal position, setting policy for the Confederacy and guiding and shaping the laws and attitudes of the land. Vice President, while less of a decision making position, is a more hands on in the implementation of the President's vision and on the execution of foreign policies.

The Confederacy is additionally run by administrative Branches. The Records Branch deals with record keeping and statistical information. The Justice Branch requisitions resources from the Spinward Arm to enforce the laws devised by the Legislative Branch. The Development Branch is in charge of building and maintaining infrastructure from roads to bridges to buildings. The Systems Branch is in charge of off-planet facilities, space ports, stations, and other federal systems resources.

Local planetary governments are essentially independent entities but are expected to maintain sufficient local equivalents to federal Branches to interact with them effectively.

The Spinward Arm
The Spinward Arm is where the real action and power of the Spinward Confederacy lie. The Spinward Arm is an enormous, complex organization responsible for law enforcement, exploration, defense, and trade matters. It is comprised of a starfleet and ground forces responsible for the defense of its members and policing of stellar trade lanes, an intelligence and enforcement branch responsible for on-world policing and security of its members, and an exploration and colonization branch responsible for locating and exploiting new worlds and resources.
