The Universal Federation was an interstellar republic, composed of planetary governments that agreed to exist semi-autonomously under a single, central government based on the principles of universal liberty, rights, and equality, and to share their knowledge and resources in order to defend from all outside threats and to explore the galaxy. Starfleet was incorporated as the peace-keeping and humanitarian armada of the Federation , in addition to exploratory, scientific, and diplomatic functions.
The history of the Universal Federation begins in the year 2381. It was formed after most of the races in the galaxy realized that they could not defeat Species 10030 individually. The first races to join were Humans, Vulcans, the Klingons, and The Borg. The first battle fought by the Universal Federation was called the Battle of the Border, during which the flagship, USS Voyager was damaged beyond repair. After decades of war, each culture was able to combine their technology and they were finally able drive Species 10030 out of known existence. Since all known threats the the Universal Federation were wiped out, Section 31 came into the public eye for the first time. Over the next 200 years, many members of the Universal Fedearation grew tired of their invlovement (most notably the Romulans). this lead to rebellions, the most famous of which, the United Rebel Front, appeared in the year 2528.
