Terran Republic (Res publica Terra)
"
'First of equals', my ass! There's nothing 'equal' about living in a Martian zoo!" -
Joseph Anderson, True Terran resident from Novum Eboracum, Terra.
The Terran Republic is, for all intents and purposes, a misnomer. Centered on the 'provisional' capital of Mars, the Terran Republic prides itself as the custodian of a ruined homeworld, restoring life to a blasted nuclear hellscape as humanity's oldest planetary colony preached for unity and loyalty in a divided universe. But while its official history exalted the founders of the Terran Republic in quashing the separatist sentiments of the nascent Martian colonies, many within and outside the Republic know the truth. From the vast metropoli of Olympus Mons, to the overabundance of Martian senators representing the most far-flung provinces of the Republic, the reality of Mars' preeminence in Terran affairs is impossible to hide. The ironically named True Terrans, especially, see nothing but hypocrisy on the part of their new overlords, where decontamination and relief efforts has proceeded at a glacial pace, while many worked in the biodomes' hospitality sector to cater to wealthy Martian pilgrims. With much of the Terran budget reserved for expensive military expeditions to subjugate 'rebel' colonies, opponents of the regime have taken to calling its elites by their true, Martian names. Such was the constant mockery that the demonym had become an insult to many Martian-born Terrans. But as one Martian-born botanist on Terra once said, "it is the unvarnished truth. We are aliens lording over another world. The least we can do is not steal their very name to pursue delusions of conquest."
Combining the symbols for Earth and Mars, the flag originally represented the planetary capital of Mars alone, with the official flag meant to feature only the Sun-cross. There had been plans for variants of the Sun-cross flag for other planets and colonized bodies in the Terran Republic, of which some were briefly used after the respective colonies' incorporation into the Terran Republic. But as time went on, Terra's continued ecological decay and Mars' preeminent position had made the Martian variant its official standard across the entire empire. Given Martian society's overwhelming contempt for the 'mutated' and 'diseased' True Terrans, the Terran Republic remains unlikely to live up to its name.
OOC: Finally, I thought of something. To put it in summary, it's a Martian empire using its control over Earth as a justification to unify humanity under its banner.
