In , the United Provinces of Plagosi constitution was introduced by King Yamato and the Mori-Conventus, officially replacing the Amberian-Urcastle Commonwealth constitution.
== History ==
=== Amberian-Urcastle Union ===
In March 2022, the Duchy of Amberia launched a revolt against its overlord, Osteri Plagosi Trading Company. They swore loyalty to the Empire of Seahaven as a result of what they considered unlawful and extortionate taxes which had been imposed on them by the former governor general Edd. During this time, the OPTC town of Urcastle became Amberia's biggest supplier of war equipment, building materials and food, causing Urcastle to massively profit from the revolt.
Due to Amberia relying heavily on Urcastle exports to not only survive but continue its revolt, it had decidered to guarantee Urcastle's independence in , which was welcomed by Yamato of Celastris and PenguinRH, the two leaders of Urcastle. 
Afte Amberia's official guarantee of Urcastle independence, the two nations signed the Urcastle-Amberian Unification Treaty in , forming the Amberian-Urcastle Union. This effectively comined Urcastle's economic and Amberia's military power. Due to the treaty, Urcastle was granted Amberian land in southern Plagos, was given the title of duchy and renamed into the Grand Duchy of Urcastle by the Kingdom of Amberia.
The Amberian-Urcastle was short lived and dissolved on in due to the Treaty of Amberia coming into effect. Despite Amberian calls to remain in the union, paragraph five of the treaty, which marked the end of the Amberian war against the OPTC, mandated that all "Treat[ies] that Amberia has made with others will all get Canceled [sic]."
The Kingdom of Amberia was subsequently re-integrated into the OPTC and renamed to province of New-Jades while the Duchy of Urcastle was able to keep its title, being granted official ownership over the land transferred to them by Amberia.
=== Amberian-Urcastle Commonwealth ===
The Union was briefly re-formed by former leader Yamato of Celastris in , a day after he was appointed acting king of Amberia. The entity was renamed to Amberian-Urcastle Commonwealth on the return of Parrotcraft123 in to protect it against instability within the OPTC. In the same year, Urcastle agreed with Freaktown's owner Jumpercali that Freaktown would officially join Urcastle and the Amberian-Urcastle Commonwealth as a whole.
Throughout August 2022, after the OPTC government collapsed almost entirely due to internal revolts, the Commonwealth would be seen internationally as the de facto OPTC government after gaining control over the majority of their lands. Urcastle also became the de facto government of the Commonwealth due to minimal Amberian influence, 
During this time, Commonwealth leader Yamato held unsuccessful diplomatic negotiations with the OPTC rebels. Shortly after the negotiations, the rebels threatened the Commonwealth and rebel leader Banetysto stated that "the Commonwealth very mean [sic] of existence will be gone [...] I gonna blob the Commonwealth when I gonna assume charge of the O.P.T.C.". These constant threats resulted in Yamato declaring war against the rebels in , achieving a quick surrender of the rebels, which resulted in NiuewLyonesse's integration into Urcastle.
From to , Yamato lead a debate in the Commonwealth parliament regarding the membership of Commonwealth membership of Fearg. While Amberian members of parliament wished to integrate Fearg into the province of Amberia, the Urcastle faction promoted the establishment of a permanent Feargian in the Commonwealth while introducing constitutional amendments allowing towns to be members of the Commonwealth without integration into Amberia or Urcastle.
In , the Commonwealth joined Simulami as a fully autonomous sovereign state, ending the period of OPTC instablity. In , Yamato of Celastris disbanded the Commonwealth. The Commonwealth parliament, supported by Amberian leader Parrotcraft123, favored disbanding in the wake of OPTC threats toto declare the Commonwealth rebels and trigger a Simulami invasion.
=== Second Amberian-Urcastle Commonwealth ===
In , after receiving confirmation from Simulami that they would not declare war on the Commonwealth, the Commonwealth reformed itself despite OPTC protest.
After reforming, OPTC leader Siam_Man threatened to remove Amberian leader parrotcraft123 from power and dismantle the Duchy of Urcastle. In reaction, the Commonwealth launched a coup against the OPTC government in . During this conflict, Simulami declared neutrality in the civil conflict under the condition that neither the Commonwealth nor the OPTC call external allies to war. If either party to the conflict was to involve other nations, Simulami committed to intervene against the nation involving outside forces.

mFour hours after the coup, the OPTC town of Bachsburg joined the Commonwealth, causing Commonwealth leader Yamato to convince the parliament to allow constitution amendments allowing towns that were republics to be under intergovernmental instead of under duchy control. These amendments also gained Bachsburgs leader Ludwig von Bach an advisor seat in the Commonwealth Parliament.
During the next week, the Commonwealth engaged in unsuccessful talks with the OPTC government regarding peaceful annexation. The OPTC instead offered all Commonwealth leaders a seat on the OPTC Stadtholder Assembly as well as the promise that Urcastle would be able to retain its territory. This deal was answered with the Commonwealth's offer grant all OPTC town owners seats in the Commonwealth parliament, reorganizing the OPTC territory through popular referendums. Both offers were rejected and diplomatic talks broke down with both parties unable to reach a compromise.
In , Hollenkreis declared its intention to join the Commonwealth and was subsequently granted an advisor seat within the Commonwealth Parliament. In , the Commonwealth merged its military with Volkard as a result of a military pact, signed between Yamato of Celastris and Jared Von OblitusOris. The following day, Yamato conducted talks with Litlkoala, the Premier of the Maritime Republic of Corodova. Corodova became an official vassal of the Commonwealth, gaining a seat in the Commonwealth parliament.
=== United Provinces of Plagosi ===
In , Amberia called a vote in the Commonwealth Parliament to conduct a merge he Commonwealth with Seahaven. The vote failed and the Duchy of Amberia declared open rebellion against the Parliament Loyalist fact. In , Amberia surrendered and was re-integrated as a province of the Commonwealth, which was subsequently renamed to United Provinces of Plagosi. The Maritime Republic of Corodova also became a integrated vassal of the UPP.
In , Yamato, now King of the UPP, abolished all political rights of the parliament and the provinces, transferring them to a newly created cabinet named the Mori-Conventus. This further centralized the UPP, consolidating the power of the monarch and effectively rendering the local governments powerless.
=== United Plagosi Provinces of the Osterium ===
In , the United Provinces of Plagosi signed the treaty of Lonely-Light was signed by King Yamato and Governor Siam_Man. The treaty resulted in the UPP annexation of the OPTC towns of Lonely-Light and Ariksprings, which merged to form a single UPP province. Lastly the country was renamed from The United Provinces of Plagosi to The United Plagosi Provinces of the Osterium. The UPP was subsequently renamed to United Plagosi Provinces of the Osterium. Its flag was changed, replacing the Urcastle banner with the OPTC banner whilst keeping the symbol representing the Commonwealth Parliament Loyalists.
==== Civil conflict ====
Shortly after his consolidation of power, Yamato declared war on Hollenkreis in , citing threats to annex the town of Castra-Fulmen and the intention to petition Simulami to grant a vassal status independant from the UPPD. Yamato further accused Hollenkreis of attempts to drive Amberia and Fearg into open rebellion, directly threatening the authority of the monarch. 
In , the UPPO agreed to the Maritime Republic of Corodova's demands for independance, althoug UPPO leadership retracted their statement the same day, after accusing members the MRC government of conducting raids against Urcastle city. Shortly afterwards, the UPPO declared war against their former vassal which resulted in a military alliance between the MRC and Hollenkreis. The UPPO's declaration of an offensiive war against the MRC also triggered the MRC's mutual defense agreements with the Yurian Shogunate and Maritime Dominion of Dualfinia, both of which subsequently entered the war in support of the MRC. This lead to the dissolution of the UPPO's non-aggression pact with Dualfinia.
Despite the UPPO's declaration of war, no large scale battles were lart of the conflict. Political instablity within the MRC lead to an internal conflict between the factions of litkoala an whenkoreasus, both of which declared themselves Premier of Corodova. Whenkoreasus, a private citizen without a government position owning large parts of Corodovan land, offered the UPPO the full annexation of the MRC and committed to transfer command of the MRC military to the UPPO monarch under the condition that the UPPO would appoint him as the leader of the MRC. While the UPPO signed the treaty proposed by whenkoreasus, litkoala's faction publicly declared the agreement illegimitate, claiming that whenkoreasus was never the Premier of the MRC and thereby unable to agree to treaties in the name of the nation. After leaving MRC territory in anticipation of an invasion, litkoala declared a government in exile hosted in Dualfinia. litkoala subsequently declared war against the UPPO, provoking Grand Castell-Llozhar and Volkard to announce that they honored their defensive commitments to the UPPO. In turn, the Dualfinian goverenment dropped its support for litkoala and declared its neutality in the conflict.
Shortly after Dualfinia's withdrawl of support, the UPPO entered secret talks with the Yurian Shogunate, sharing information on the raid againist Urcastle allegedly carried out by MRC forces. These talks resulted in a non-aggression pact between the two parties which was signed in . The UPPO further announced a public guarantee of Yurian independance, deepening the relations between the two nations. This diplomatic shift was further exemplified in , when the Yurian Shogun Nagisa Yamato invited King Yamato to his wedding. Lacking support and recognition by its former allies, litkoala's government in exile failed to furhter engage in the conflict in any major capacity.
In , Simulami publicly pledged their support of the UPPO against Hollenkrei which had decided to reform to Plagadonia and engaged in peacetalks with the UPPO, moderated by Simulami. Plagadonia argued to Simulami that King Yamato had declared war against Hollenkreis for no valid reason other than to exercise his power. The UPPO government responded by claiming that the declaration of war against Hollenkreis after consenus in the Mori-Conventus which found Hollenkreis guilty of committing treason against the monarch by threatening to annex Castra-Fulmen and inciting Amberia and Feargh to declare independance. Peace talks concluded in when Plagadonia petitioned Simulami to grant them vassalship independant from the UPPO. Simulami declined by reaffirming support for the UPPO govenment, which lead Plagadonia to declare its surrender.
==== Simulami Semi-vassaldom ====
Facing constant internal instability and threats, the UPPO asked Simulamim leadership to lower its status to that of a semi-vassaldom in . Upon officially becoming a part of the Simulami Empire, the UPPO subsequently changed its flag to include the Simulami ensign in the corner. The status of Semi-vassaldom still allowed the UPPO to independantly engage in foreign policy and exercise legal control over its territory.
In , the UPPO signed a treaty with Volkard, agreeing on the annexation of Volkad by the UPPO. The treaty came into effect in , granting the UPPO an Eldhamite province for the first time since its inception. However, Eidenburg became the first official UPPO territory in Eldham, when Jared Von OblitusOris, the leader of Volkad, gifted the island to the UPPO in a seperate agreement in 
==== Amberian Independance movement ====
After a prolonged period of the Amberian Independance faction, led by Parrotcraft123, King Yamato suprisinigly called for an emergency meeting of the Mori-Conventus in . Parrotcraft123 revealed that he had engaged in talks with the Osterium Pirates, offering to sell them ownership of Amberrian lands to further his ambition of gaining Amberian independance from the UPPO. After his statement, the King and his cabinet denied consent for Amberian independance, stating that Amberia, being a core province of the UPPO, could not be sold to foreign powers. In response, Parrotcraft123 mobilized the Amberian Independance faction, threatening to damage the UPPO economy and evict UPPO citizens from Amberian territory.
King Yamato subsequently called another Mori-Conventus meeting, calling a vote on whether to strip Parrotcraft123 of his land ownership to prevent threats to national security while allowing him to keep his political office within the government. A consensus decision was later declared invalid after unrest within the government and citizenry, which argued that the removal of a province leader was an act of tyranny. Prolonged debate and four further subsequent votes resulted in a vote in favor of the removal which was supported by five out of the seven members of the Mori-Conventus.
After further debate and talks, a compromise was reached in . Instead of being expropriate while keeping his political office, Parrotcraft123 agreed to resign from the office of leader of Amberia if he was permitted to retain ownership over of Amberian land as a private citizen. In , a session of the local Amberian senate was made public, revealing that Parrotcraft123 stated that he had no intention of actually signing the proposed compromise, rallying his faction to prepare a rebellion against the UPPO leadership. After the Simulami goverment authorized the UPPO to declare war on Amberia, the declaration of war against a core province was met with heavy opposition. King Yamato was repeatedly accused of tyranny while SepherHN's resigned from the King's cabinet. 
==== Intervention in Ardune ====
Throughout December 2022, King Yamato assumed the office of head of diplomacy and all political affairs in the Eldamit nation of Ardune. By controlling both the external and internal affairs of Ardune, Yamato accumulated far reaching political influence within the nation, deepening the connection between the two nations.
When the Kingdom of Malucia declared independance from Ardune in , the UPPO not only intervened in the conflict militarily, but also called for support of its own allies, despite not being the target of the Malucian declaration. This elicited heavy critisim both internationally and in Ardune, since the Emperor of Ardune previously granted independance to Malucia.
==== The Anti Monarchist Movement ====
In the former high council member and joint founder of The nation Rhapsody Azadivar started a anti-monarchy movement against King Yamato due to being increasing unsatisified with what he called Yamato's Tyrannical imperalist regime. In the information was leaked to The UPPO government and King Yamato began to open up talks with The anti monarchist movement. The UPPO government strongly denied the claims of tyranny and imperalism, using the Parliament and Mori voting and legal progresses as evidence of The semi-democracy they argued existed throughout the nation. Rhapsody Azadivar however would go onto take a strong rhetoric stance against King Yamato and with the on-going stresses of The UPPO-Amberian conflict King Yamato became plagued with a psychotic episode becoming unresponsive to all governmental matters leading acting head Jumpercali and Sheepy in-charge of running the nation. 
Jumpercali and Sheepy would refuse diplomatic talks with The anti-monarchy movement and called on The Empire of Simulami to honour The UPPO semi-vassaldom treaty against The movement. King Yamato's consort at the time Visla Celastris would begin talks with The anti-monarchy movement with no political authority in-order to secure King Yamato's place within the new government if a coup would occur. 
King Yamato regained his senses later within the re-instating all anti-monarchy movement members to their positions within The UPPO, annoucing that The UPPO government would fight all those that raised their flags in open rebellion and recommended that the movement raise any and all concerns to The UPPO parliament and follow The current constitution. The anti-monarchy movement soon collapsed, starting and ending in The Summer of 206TE and resulted in Rhapsody Azadiva's banishment from The UPPO and all other members of the movement being royal pardoned post Mori vote.
==== The UPPO Simulami - Lunari war ====
In The post The UPPO declaring war on Amberia, Lunari joined the conflict and would defeat UPPO and Simulami forces annexing The UPPO now known as The Kingdom of Osterium and all of Simulami Plagos. The entire province of Amberia was also annexed as a seperate Lunari state however was later sold back to The Kingdom of Osterium in The Sping of 220 TE. Osterium would however lose The previous OPTC capital of Lonely-Light to Kartek. 
== Culture ==
The UPPO's primary cultures are from the Osterian culture group, which is consists of OPTC, Plagosi, Urcastle, Fearg and Amberian influences. The culture is also heavily influenced by the Bloodstone Cult. Migrants from the Maritime Republic of Hansa and Seaside are also present in the nation, while some Lunari refugees also reside in the UPPO since the annexation of the Lunari Empire by Seahaven.
Since , the UPPO slowly embraced new culture called Nekoism, in which cat ears are very popular. Feline humanoid species such as Nekojin and Kumiho are becoming treated as devine figures within the nation by some. In , the government adopted the term Plagosi NEKO to describe all citizens the nation, however it should be noted that citizens who reside in the Southern Islands still consider themselves Osterian. Parliament members also bekame known as Parliament NEKO's. The monarch is since referred to as Purr, the most ridespred most revererd entity in the Church of Barry the Blue Sheep after Barry himself
Osterian Folklore is also quite prominent and still retold among the Southern Islanders, expectially within Feargan and Bachsburgian groups among others. One of the oldest legends of Osterian Folklore is the legend of the great "Flaithis War" a mythologial war claimed to have taken place melenia ago. Between the antctient Osterians and the lost race known to the Osterians as the Roinn People, claimed to be the antient enemy of the Osterian people and according to the myth the Osterian people were pushed to the edge of the Osterium by the Roinn where then the finest Osterian blacksmyths forged the Osterian Ranger armor and it is said that this piece of equipment specfically corrolated to a successful counter attack that saw the Osterians retake most of the Osterium. In spite and wrath the bitter Roinn people chose to sink the Osterium by use of a dark ritual instead of allowing the Osterian people the access of their ancestural lands which saw only the moutain settlements within the Osterium remaining above the surface, these mountain settlements later became the largest cities within the Osterium.
