UNEM

The UNEM (United Nations of Earth and Mars) is the governing body of humanity."Earth largely controls the politics of the UNEM and always has, much to the disdain of those on Mars. Mars is known for being a planet largely controlled by corporations and the wealthy, as once terraformation was well underway and large swaths of Mars became habitable, it was a Wild West for profit-seekers as the UNEM (then just the UNE) couldn't keep up with the masses of people migrating to Mars and the private interests getting their footholds on the 'new world.' Eventually when the UNE sought to bring both planets under one system of government (UNEM), there was a lot of controversy, eventually leading to the Martian Independence Rebellion (MIR) as both private citizens and the corporations wanted to be free of the 'old world's' (Earth's) control and go their own way, as they knew they'd ultimately be subject to whatever Earth wanted and that Earth's interests would always take precedent (and they weren't wrong about that). However, the MIR was eventually crushed by the UNE and the UNEM was formed. A second MIR eventually occurred, but it was squashed even quicker. Ultimately, it was the revelation of the Coalition, the prior quelling operations, and the knowledge that the Coalition would return again that forced everyone's hand into working together to combat a mutual threat, bringing us to where we are now. Though things are still divisive between the two planets and the politics tend to be bitter, the UNEM has never been stronger or more unified."
