The Terran Federation

In 2098 the United Nations were based on mars when they discovered that a cold war over the ownership of Titan went down causing a large amount of tension between countries that had moved away from earth. China and Russia wanted to have control and claimed it was unfair that the United Kingdom had claimed the entire moon for themselves and the United States wanted to turn it into a commercial planet with bustling cities full of stores and hotels and holiday parks. This cold war almost went hot, but in 2113 a peace treaty was finally signed allowing each country to take ownership of a certain moon around Jupiter and they made Jupiter the United Capitol where the United Nations would hold talks and all matters of the galaxy would be relayed and in 2124 a city was built there called New Earth City with a population of more than 6 thousand people, it was the most populated off-earth city in the sol system. Finally in 2132 the united nations and all counties associated with it agreed to join together as one, the Terran Federation (Officially: The United Federation of Earth) with their capital on Titan. The situation with the federation suddenly changed when in 2150 the Montergians caused the mass exodus of Earth and kicked the last few thousand humans off-world to live with the rest of the federation.

Politics
In the beginning of the Federation the government was run the same way the United Nations currently are, with 5 permanent members of a security council with the most decision making power in the galaxy (at the time). however as more countries dissolved into this federation, less and less people were happy with this ancient set up of allies from a war that ended almost 200 years ago and, so, something had to change.
