Flag of the United Earth Empire(ooc: an alt-federation essentially), the main governing body in the
Mobile Suit Gundam Trilogy(ooc: meaning not the three compilation movies, but Mobile Suit Gundam, Mobile Suit Zeta Gundam, and Mobile Suit Omega Gundam, which is alt-Gundam ZZ) by Yoshiyuki Tomino. The anime trilogy takes place in an alternate timeline where the American Union State won the second civil war, and Germany and an increasingly authoritarian Entente joined forces to defeat the Internationale, and were then engaged in a Cold War with the National Populist bloc led by Pelleyite AUS and Russia. This culminated in a cataclysmic nucelar war between the League of Nations and the Eurasian Alliance that saw the League of Nations presiding over a devastated world. The League of Nations reformed into a one world government--the United Earth Empires, a worldwide constitutional monarchy, and started a period of Space Colonization, hearlding in the era of the Universal Century.
However, the construction of Space colonies only ushered in a new age of warfare. Because the nuclear war devastated much of the planet, there were not enough resources to sustain the population. This lead to a forced population transfer of the lower class into the space colonies to work to provide a source of resources via asteroid mining and food production. Eventually the colonies start to demand independence. However, while there are genuine reformers in the world congress that want to give the Colonies more autonomy, they are held back by the structural problems within the Empire. The government is tilted more towards conservatives and the nobility, which often opposes independence. Furthermore, the Empire is a very decentralized system prone to regionalism, with certain regions, mainly those either dominated by conservatives or are economically reliant on the colonies being much more hostile towards the Space colonies getting any independence having an excessive amount of dominance. This led to an unholy alliance of conservative nobility, business interests, administrative regions that are against greater autonomy for the colonies, as well as outright Terran supremacists, that stifile independence movements in the Colonies. The failure of the Empire to deal with these structural problems will lead to it's collapse at the end of
Mobile Suit Omega Gundam
The portrayal of the Empire as bogged down by regionalism and surviving nationalism giving way to political corruption has led to accuations directed Tomino of implicit Syndicalist or pro-CSA/Internationale bias, through Tomino has denied this, rather wanting a narrative where both sides in a war could be seen as "wrong", with the soldiers fighting either for survival or for ideals that may be perverted by the leadership or by circumstance. In this case the soldiers of the Empire are portrayed as fighting not just to defend Earth, but also to defend the ideals the Empire was founded on despite the failure of the government to achieve such ideals, or even to defend the sovereignty of their administrative regions, which they fear would be taken away from them by a more centralized and totalitarian government. The Leader of the Imperial Space forces in Mobile Suit Gundam, Grand Admiral Revil, is presented as an reformer who wants to centralize the Empire, but to use that power to carry out sweeping reforms to oust more conservative factions and give the colonies more autonomy.
OOC: Essentially I made alt-federation a bit more "relatable" to say the least rather than a monolithic bloc of oiligarchs that are effectively what we would call maliciously incompentent for the sake of being maliciously incompentent with little to no characterization than greenlighting the Titans and letting people die for the sake of population control. It's still a highly corrupt and oppressive entity, but the reasons for it's corruption are grounded in a lot of factors such as being VERY dysfunctional and prone to internal squabbling(let's just say this alt-federation would have collapsed a long time ago had it not been the fear of Zeon rebellions to interval divisions and the decentralization) instead of being maliciously incompentent for the sake of it, so in a sense it's a bit more "pitable" than the OTL federation, also EFSF soldiers are given reasons to fight for the alt-federation the same way Zeon soldiers do in both OTL and TTL despite Zeon being a Savinkovist and Nazi entity in TTL and OTL respectively instead of just fighting against Zeon because they're the "protagionists" and Zeon is "invading". Also the forced population transfers are given at least a bit more sympathetic context(the whole Earth being a near wasteland and resources being almost depleted), even if they are not justified.
OOC: I did not use the original Zeon flag because Nazism dosen't exist in TTL so had to grab some other varient. Also the Zeon symbol in the First Order flag does kinda make it look like a Savinkovist flag.....
Flag of the Duchy of Zeon(ooc: No, it's not called the principality here), formerly the Republic of Zeon. Zeon was once comprised of the colonies of Sector 3(ooc: Side 3), but they declared independence from the Empire after a successful rebellion by the populist republican Zeon Zum Deikun. Deikun declared the formation of the Republic of Zeon and established the ideology of Contolism--mainly the idea that humanity must leave earth and all live in space to allow the earth to heal, and that humanity in space will evolve into a "new type" of being that can transcend petty nationalisms and embrace understanding. However he was killed by Imperial "loyalists" led by the noble Degwin von Zabi. It turns out however, Degwin was using the Empire as a pawn to facilitate the consolidation of his own power and in a span of few years declared the Duchy of Zeon, cut off all relations with the Empire, and prepared to launch a war of independence.....
However, others in his government has much more sinister goals, in particular his eldest son, Gihren von Zabi. An admirer of national populist ideology, Gihren gradually, through political manuverings, would gradually subvert his father's powers to turn Zeon into a Legionary state with the goal of dominating all of the Earth Sphere and destroying the "inferior Earthnoids". Unknown to any of the Zabis however, the surviving son of the Deikun family--Casval Rem Deikun has secretly infiltrated the military as Char Aznable--the Red Knight of Zeon, and seeks to destroy the dutchy from within to avenge his father.....
While Zeon are portrayed as the "antagionists", and Gihren and his Savinkovist ideology is seen as wholly villainous, the greviences that drove Spacenoids to in Sector 3 to side with Zeon or overlook Gihren's racist ideology is seen as legitimate. Zeon soldiers are presented as well-rounded individuals, not all of them being national populist fanatics, with many being unware of the perversion of the independence war that Gihren is doing behind the scenes. Even some of the Zabis themselves are presented as sympathetic, with the character of Garma von Zabi and Dozle von Zabi objecting to the worst of the atrocities being carried out; the former even being seen as having a genuine desire to achieve reconcilation with the Earth Sphere while the latter is presented as a loving father(ooc: Yeah this will probably cause the same issues OTL, but less militaristic Japan + more relatable federation--I mean Empire and their soldiers also being treated the same way as Zeek grunts as fighting for a higher ideal, abeit perverted or corrupted ones themselves may mean less Zeon apologia, furthermore making every Zeon mustache twirling national populist villains just to weaken Zeon apologia kinda kills the point of gundam IMHO, so I tried to avoid that)
