Line #7 Main/PlanetaryNation


1	Ah, Earth. Full of many nations, territories, countries and governments. And yet when alien homeworlds are visited, we only get to see one government.
2
3	This is an OmnipresentTrope in Science Fiction where inhabited planets not named Earth are shown to have only one government. The reasons range from someone succeeding in [[TakeOverTheWorld taking over the world]] to being a mere PlanetOfHats to the fact that [[SkeletonGovernment politics limited to one world]] are [[LawOfConservationOfDetail unimportant to stories with interplanetary settings]], or because SciFiWritersHaveNoSenseOfScale and think that [[{{Planetville}} the planet would be akin to a town or city]] instead of a large sphere that can hold hundreds of countries and millions of cities and towns.
4
5	This trope can be justified in a couple of ways. If the planet was recently colonized, there may not have been time for it to develop more than one government. The entire population could be a few thousand to a few million people living in and around the first colonization site. On the other side of things, on a homeworld or a long-colonized world, extending power over a planet is ''much'' easier than extending it into space. The one-world government can easily put down unrest on the next continent, but subduing another planet in the same system requires several orders of magnitude more effort, by any known or likely means.

7	If ''Earth'' is this, see OneWorldOrder. Compare with SingleSpeciesNations, which commonly used this trope as justification. The aversion is MulticulturalAlienPlanet.

14	[[folder:Anime & Manga]]
15	* ''Anime/BraveRaideen'': The Demon Empire is led by Emperor Barao, and it's implied that their political system is a monrachy as he's [[AmbiguouslyRelated more or less related]] to Prince Charkin.
16	* ''Anime/FutureRobotDaltanious'': Each planet has one ruling family, such as Helios, Zaal, Marios and Proxia. There are also cases of Royals from different planets marrying and having children. Even the main character is half-Earthern and half-Heliosian.
17	* ''Anime/{{Gigantor}}'': The Demon Empire[[note]]No relation to the one from ''Anime/BraveRaideen''[[/note]] is led by King Uchuumaoh. While he isn't from a Royal Family himself, he was once a human who was corrupted by a black hole, and gained immense power as a result. This also led to him acquiring many dedicated followers who joined his empire.
18	* In ''Anime/TransformersCybertron'' Gigantion and Velocitron are like this. The politics of Gigantion are not really looked at, but there is only a single city on the entire planet, presumably under one form of government. Velocitron is governed solely by who is the fastest racer. The politics of this position is not essential to the plot, so it was not looked at.
19	* After the transition to the much more decentralized New United Nations in the ''Anime/{{Macross}}''-verse, NUNS-affiliated worlds such as Eden and Ragna now play this trope straight by the time of ''Anime/MacrossDelta''. The independent world of Windermere is also an example.
20	* Frequent in the ''Anime/RobotRomanceTrilogy'', where [[Anime/CombattlerV Planet Campbell]], [[Anime/VoltesV Planet Boazania]] and [[Anime/{{Daimos}} Planet Baam]] are all led by one monarchy each. Though, with the last one, the destruction of Planet Baam causes some Baam to follow the son of their former ruler, Richter, while others choose to follow the lead of Erika on [[LaResistance Utopia]].

23	[[folder:Comic Books]]
24	* ''ComicBook/BlackMoonChronicles'': ZigzaggedTrope. After humanity settles on a new world after the forces of evil have destroyed the old one, [[TheArchmage Methraton]] tells the human nations that they have to pick one emperor from among their kings who will rule over the entire world, as he won't allow any more pointless warring between them. They select Wismerhill when he is the only monarch to refuse the throne. However, the other kings seem to retain a degree of autonomy (and their titles), given the feudal setting.
25	* Discussed and deconstructed in ''ComicBook/RomVsTransformersShiningArmor''; the member species of the Solstar Order all underwent extreme globalization before achieving space flight... making them totally unprepared when they encounter other species that ''haven't'' gone through this. The Space Knights find the idea that Transformers still have civil wars and multiple, opposing governments after reaching space [[BlueAndOrangeMorality to be utterly bizarre]].
26	* ''ComicBook/WonderWoman1942'': The entirety of Venus is ruled by Queen Desira.
27	[[/folder]]

29	[[folder:Films -- Live-Action]]
30	* In ''Film/ManOfSteel'', the whole planet of Krypton is governed by a high council. This isn't explained in depth, though.

33	[[folder:Literature]]
34	* Chris Moriarty's ''Spin Control'' series draws a specific contrast here. Earth's offworld colonies all have unified world governments under United Nations jurisdiction, but Earth's nation-states still exist and provide an unexpected wrinkle to any negotiations with the homeworld.
35	* This is nearly always true in the ''Franchise/StarWarsExpandedUniverse''. One of the few exceptions is the planet Adumar in ''[[Literature/XWingSeries X-Wing: Starfighters of Adumar]]'', which contains several competing alliances of nation-states. The New Republic and Empire start out negotiating with the most powerful one without fully understanding this, leading to problems. Another occurs in a young adult novel with Obi-Wan Kenobi as a Padawan when he goes on a mission to a planet in the midst of a centuries-old civil war. They can't even agree on the planet's ''name'', with the Melida and Daan factions both naming it after themselves, so the Republic calls it Melida/Daan.
36	* Most of the nations, planets, and Space Stations in the ''Literature/VorkosiganSaga'' are this. The few exceptions are the Cetagandan Empire and Barrayaran Empires, which are nations made up of ''multiple'' planets, and Earth, which is still split up into a gillion countries like today. Jackson's Hole is made up of numerous Great and Minor Houses, which are functionally countries in their own right.
37	* As usual, ''Literature/HonorHarrington'' never fails to provide examples of all tropes sci-fi, both...
38	** Played straight:
39	*** The Protectorate of Grayson, a CultColony established by a bunch of SpaceAmish which gets rather abruptly drawn into galactic affairs due to being smack in the middle of an interstellar cold war. They [[TookALevelInBadass grow teeth]] very rapidly.
40	*** The Kingdom of Torch, a planet of liberated genetic slaves.
41	*** Mesa, the planet ruled by a corporation... allegedly.
42	** And averted:
43	*** The Star Kingdom of Manticore starts out as a single-system (but three-planet) star nation which is punching well above its weight class thanks to the Manticoran Wormhole Junction. Later events turn them into the Star ''Empire'' of Manticore. This was not Manticore's idea.
44	*** The People's Republic of Haven, at its height, is stated to have over three ''hundred'' star systems under its umbrella, most by forced conquest. One MeaningfulRename and [[BoomHeadshot dramatic governmental reorganization later]], it sheds over half of those, the rest remaining voluntarily and by their own request.
45	*** The Solarian League includes an almost uncountable number of star systems and is described, only partially ironically, as "the heir to all mankind's greatness". It's also so bogged down by corruption and bureaucratic red tape that it's essentially ungovernable, and by the time the main story is falling apart at the seams.
46	* This is actually the law for colonies in ''Literature/TheGenesisFleet'', where colony permits are only given out to a single group per planet in order to avoid conflict. This is why everyone is shocked when Scatha brazenly establishes a colony on the already-settled planet Glenlyon. This just serves to indicate that there's no one to enforce the rules anymore, after the invention of the jump drive and the second wave of expansion, as Old Earth is no longer interested in being the "big brother", and neither are the old colonies. In fact, Earth is actually mothballing and selling off its SpaceNavy. The trope is definitely averted in the case of Earth, which still has the old nation-states, and Mars, which is largely run by gangs. By the end of ''Vanguard'', the Glenlyon colonists manage to retake their world, kicking Scathans off the planet.
47	* This remains the norm a few centuries later in ''Literature/TheLostFleet'', when colonisation has progressed far enough to allow for governments that span multiple worlds: How much autonomy individual worlds and regions have isn't addressed in detail, but each inhabited planet within TheAlliance or [[OneNationUnderCopyright the Syndicate Worlds]] has one unified local government for that world and any outposts elsewhere in the system. Justified by the fact that individual planetary populations are extremely low, with one hundred million people being considered quite a large number for a particularly wealthy and important system, thanks to lingering cultural hang-ups over overpopulation and environmental collapse nearly turning EarthThatUsedToBeBetter into EarthThatWas.
48	* [[LampshadeHanging Lampshaded]] in Creator/IsaacAsimov's novel ''Literature/TheStarsLikeDust'', a distant prequel to his ''Foundation'' series. The planet Lingane is a "planet state", while the rest of the human-colonized Galaxy has "passed beyond that stage of economic and political development" and most other states are "conglomerations of stellar systems".
49	* ''Literature/FoundationSeries'': This is the status of the Terminus Foundation between [[Literature/TheEncyclopedists 50 F.E.]] when the [[GalacticSuperpower Galactic Empire]] withdraws from its region of the galaxy and Mayor Salvor Hardin succeeds in securing Terminus' independence from the surrounding Four Kingdoms, and [[Literature/TheMayors 80 F.E.]], when the Foundation manages to establish political control over said kingdoms, thus establishing what becomes the Foundation Federation (though the Four Kingdoms being ''formally'' integrated into the same state as the Foundation lags considerably behind, with there being references as late as [[Literature/TheMerchantPrinces 150 F.E.]] that suggest the Four Kingdoms are technically still separate from the single-planet Foundation even if they are so dependent as to effectively be an extension). Note that, during this time, the Foundation consists of a single city and the farms surrounding it on an otherwise unoccupied planet, thus making it a LandOfOneCity as well.
50	* By the time of the Empire in the "Terro-Human Future History" of Creator/HBeamPiper, this is explicitly mandated by Imperial law. The Imperial Constitution states (quoted in the novella "A Slave is a Slave"):
51	-->Section Two: Every planetary government to be sovereign in its own internal affairs.... Only one sovereign government upon any planet, or within normal-space travel distance....
52	* The Oyarsa from ''Literature/OutOfTheSilentPlanet'' is recognized as the single authority across all the races and towns of Mars, owing to his status as an EnergyBeing with an ancient and transcendent intelligence.

55	[[folder:Live-Action TV]]
56	* Most planets on ''Franchise/StarTrek'' are examples of this trope. When a planet isn't united, the Federation basically considers it to be in a state of civil war, even if the nations aren’t actually fighting each other. Earth throughout most of its history was presumably in civil war, and (except for some arguable periods of peace) continued to be at least until around 2150 AD (almost nine decades after first contact with the Vulcans ironically enough) when the last holdout finally joined [[OneWorldOrder United Earth]]. Some Federation planets (such as Vulcan) have had Planetary Nations virtually into antiquity.
57	** In the ''Series/StarTrekTheOriginalSeries'' episode "[[Recap/StarTrekS2E21PatternsOfForce Patterns of Force]]" a Federation scientist decides to unite the planet he's observing under one government - unfortunately, he concludes that Nazism is the best way to unite the planet.
58	** One episode of ''Series/StarTrekTheNextGeneration'' had an aversion. The planet was ruled by two separate governments, the Kes (not to be confused with the character on Voyager) and the Prytt, who were engaged in a cold war with each other. The Kes were applying for Federation membership and Picard lampshaded this trope when he mentioned planets that join the Federation are usually unified. It's never said whether or not the Kes would be admitted but it's implied they won't be (though the implication is that the main issue is the Kes ''attitude'' towards the Prytt more than the technical fact of there being two planetary governments).
59	* Usually played straight in ''Series/StargateSG1'', although in most cases this is because there's really only one or two settlements of note (blame the Goa'uld). Two exceptions are Langara, which has at least three major powers, and Tegalus, which has two, and in both cases each are in a SpaceColdWar with their neighbors.
60	* Very common in ''Series/DoctorWho'', with Galiffrey being a prominent example. It's only shown form of government is a council that [[Recap/DoctorWhoS23E1TheMysteriousPlanet tried to get the Doctor on trial]] and [[Recap/DoctorWhoS30E17E18TheEndOfTime much later try to destroy the entire universe]].
61	[[/folder]]
62
63	[[folder:Tabletop Games]]
64	* While single planetary governments are the norm in ''TabletopGame/{{Traveller}}'', {{balkaniz\|eMe}}ation is common enough that the Third Imperium (a very loose interstellar government) allows limited intraplanetary warfare, so long as they keep it to one planet and don't resort to nukes.
65	* Usually the case for human-inhabited planets in ''TabletopGame/Warhammer40000''. The Imperium is so large that any given planet is usually ruled by a single governor (how they're chosen, what they are internally called, and whether the post is just a figurehead for whatever faction is actually calling the shots varies from planet to planet, though the Adeptus Administratum will officially refer to them as a Governor of the Adeptus Terra regardless of whether its President or King or whatever else internally). They're usually given full control of their planet and left alone, as long as they pay their tithes, make sure the Imperial Cult (or locally approved variation) is worshipped by all inhabitants and don't show signs of sedition (and they don't call for help, although that's usually less effective at getting someone's attention). However, in many cases this is just to make the paperwork easier; there are several planets where the "governor" is whichever ruler or tribal warlord was winning the day Imperial officials last visited, usually technologically regressed Feral and Feudal Worlds. Some Feral World tribals don't even know the Imperium exists.

67
68	[[folder:Video Games]]
69	* Taris from ''VideoGame/KnightsOfTheOldRepublic'' seems not only be a planet with one Government, but it also seems to be a planet of one ''city''!
70	* This is a requirement to exit the Civilization stage in ''VideoGame/{{Spore}}'' to move onto the Space stage. Same goes for every other galactic empire out there, though they often have more than 1 planet; also Uprisings only happen for entire planets.
71	* In ''VideoGame/{{Stellaris}}'' planets are assumed to achieve a unified global government before attaining interstellar travel. However pre-FTL civilizations lack unified governments with their entry on the contacts menu reading "fragmented nation-states."
72	[[/folder]]
73
74	[[folder:Western Animation]]
75	* Played with in ''WesternAnimation/{{Futurama}}'' in regards to Earth itself. Earth has its own overarching government ([[AmericaTakesOverTheWorld that is somehow also the American government and based on American governmental traditions]]), but other nations are shown to still exist with their own set of laws. And then it's usually played straight when any other planets show up (which is normally OnceAnEpisode).
76	* True in ''WesternAnimation/{{Ben 10}}'' for basically every single world that isn't earth. Some have one government that covers multiple planets.
