Kingdom of Osterium

The United Plagosi Provinces of the Osterium, or the U.P.P.O. is a country in Plagos currently lead by The Duchy of Urcastle, who were the victors of the four-way O.P.T.C. civil war of September - October 2022.

First Founding
In March 2022 the Duchy of Amberia had launched a revolt against it's overlord, the O.P.T.C.. 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 O.P.T.C 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 it's revolt against The O.P.T.C. it had decidered to guarantee Urcastle's independence on the 20th of may 2022 a move which was welcomed by both leaders of Urcastle Yamato of Celastris and PenguinRH.

Following on from Amberia's official guarantee of Urcastle independence the two nations signed The Urcastle-Amberian unification treaty on the 6th of June 2022 forming the Amberian-Urcastle Union. This move was due to Amberia needing Urcastle's economy and Urcastle needing The Amberian military incase of defence.

Due to the treaty Urcastle was granted Amberian land in southern Plagos and was given the title of duchy and renamed into The Grand Duchy of Urcastle by The Kingdom of Amberia.

Collapse
The Union, however, was short lived and collapsed on the 11th of June, 2022 due to the Treaty of Amberia (which was signed before the union was formed) and became public on the 11th of June, 2022, resulting in the collapse of the Union, despite Amberian calls for it to remain.

The Kingdom of Amberia was re-integrated into the O.P.T.C. and renamed as the province of New-Jades and the Duchy of Urcastle was able to keep it's title and was granted official ownership over the land granted to them by Amberia.

Second Founding
The Union would be re-formed by former leader Yamato of Celastris on the 4th of August, 2022 a day after he was appointed acting king of New-Jades/Amberia. The union would be scrapped and Amberia and Urcastle would form a Commonwealth on return of Parrotcraft123 on the 18th of August, 2022 for it's protection due to instability within the O.P.T.C.

Gaining Freaktown
On the the same day, Urcastle agreed with Freaktown's owner Jumpercali that Freaktown would officially join Urcastle and The Amberian-Urcastle Commonwealth as a whole.

OPTC Instability Period
Throughout August 2022, after the O.P.T.C. government collapsed almost entirely due to internal revolts, the Commonwealth would be seen internationally as the de facto O.P.T.C. government after gaining control over the majority of their lands. Urcastle would also become the de facto government of The Commonwealth due to minimal Amberian influence, During this time, Commonwealth leader Yamato would undergo unsuccessful diplomatic negotiations with the O.P.T.C. rebels. Sometime after the negotiations took place, the rebels would threaten The Commonwealth, and rebel leader Banetysto would go onto state "the Commonwealth very mean of existence will be gone" and "I gonna blob the Commonwealth when I gonna assume charge of the O.P.T.C." among other threats. These constant threats would result in Yamato declaring war against the rebels on the 30th of August. After declaring war, the rebels quickly surrendered resulting in NiuewLyonesse being integrated into Urcastle.

From the 2nd to the 4th of September 2022, leader Yamato would lead a split heated parliament debate with Fearg and Amberia in the Commonwealth Parliament which resulted in an Urcastle victory. The O.P.T.C. province of Fearg officially joined the Commonwealth as an intergovernmental province. This resulted in constitutional amendments allowing towns to exist not under either Urcastle or Amberia, gaining Fearg a permanent seat in The Commonwealth parliament and gaining Urcastle new allies within the parliament. This was all passed despite disagreement about Fearg's status, due to Amberian wishes to annex the province directly.

On the 5th of September, the Commonwealth joined Simulami as a fully autonomous sovereign state, ending the O.P.T.C. stability period.

Second disbandment
On the 7th of September, after on-going pressure from the O.P.T.C. government, Yamato of Celastris disbanded the Commonwealth after their parliament and Amberian leader Parrotcraft123 pressured him to after The O.P.T.C. had threatened to declare the Commonwealth rebels and trigger a Simulami invasion.

Third Founding
On the 16th of September, after gaining confirmation from Simulami that they wouldn't declare war on the Commonwealth for existing, the Commonwealth reformed itself against O.P.T.C. wishes.

The O.P.T.C. civil war
After reforming, O.P.T.C. leader Siam_Man threatened to remove Amberian leader parrotcraft123 from power as well as to dismantle the Duchy of Urcastle. These threats caused The Commonwealth to launch a coup against the O.P.T.C. on the 27th of September, 2022.

The coup was launched after gaining confirmation from Simulami that they wouldn't get involved in the civil war as long as the Commonwealth didn't call in their allies. They also promised that if the O.P.T.C. called in allies, Simulami would side with The Commonwealth. Around 4 hours after the coup was launched, the O.P.T.C. town of Bachsburg joined the Commonwealth. This joining caused Commonwealth leader Yamato to convince the Commonwealth parliament to allow constitution amendments allowing towns that were republics to be under intergovernmental government control instead of under Duchy control. These amendments also gained Bachsburgs leader KapitanBach an advisor seat in the Commonwealth Parliament.

Over the next week, the Commonwealth opened up talks with the O.P.T.C. government regarding peaceful annexation, something they rejected. The O.P.T.C. instead offered all Commonwealth leaders a seat on the O.P.T.C. Stadtholder Assembly (high council), something Yamato already had, as well as the promise that Urcastle wouldn't be broken up. This deal was rejected by both leaders of the Commonwealth who once again attempted to peacefully annex the O.P.T.C., promising O.P.T.C. town owners a seat each in the Commonwealth parliament and promising to remake the country by populace majority. This deal was rejected by the O.P.T.C. government and diplomatic talks were beginning to fail with either side refusing to compromise further on their deals.

The Commonwealth would go onto annex Hollenkreis on the 1st of October after they willingly and peacefully joined The Commonwealth. This joining led Hollenkreis to be granted an advisor seat within the Commonwealth Parliament.

On the 2nd of October, the Commonwealth merged its military with Volkard forming a united Commonwealth-Volkard military after a joint military pact was signed between Yamato of Celastris and Jared Von Mafiafell. The following day, Yamato conducted talks with Litlkoala, the Premier of the Maritime Republic of Corodova. Corodova became an official vassal of The Commonwealth, granting them a seat in the Commonwealth parliament.

The United Provinces of Plagosi
On the 6th of October, Amberia called a vote in the Commonwealth Parliament suggesting that The Commonwealth merge with Seahaven. The vote failed and the Duchy of Amberia rebelled from The Commonwealth in response. The Commonwealth was then temporary renamed to the Commonwealth Parliament Loyalists.

On the 8th of October, Amberia surrendered and was integrated as a core province into the Commonwealth Parliament Loyalists, which had been re-named to The United Provinces of Plagosi(U.P.P.). The Maritime Republic of Corodova also became a integrated vassal of The U.P.P.. On the 11th of October, U.P.P. king Yamato stripped all advisor powers away from the U.P.P. parliament and transferred their powers to a newly created cabinet named the Mori-Conventus. Yamato would also strip all province powers and transfer them to the Mori-conventus and vastly centralized the U.P.P.

On the 24th of October, the United Provinces of Plagosi was renamed to the United Plagosi Provinces of the Osterium and its flag was changed replacing the Urcastle banner with the O.P.T.C. banner whilst keeping The parliament symbol of the Commonwealth Parliament Loyalists.

The United Plagosi Provinces of the Osterium
On the 23rd of October 2022 The United Plagosi Provinces of the Osterium (U.P.P.O) was formed after the compromise treaty of Lonely-Light was signed by U.P.P. king Yamato and O.P.T.C. governor Siam_Man. The treaty resulted in the remaining towns under The O.P.T.C. banner Lonely-Light and Ariksprings surrendering to The U.P.P. and becoming a province under the old O.P.T.C. capital of Lonely-Light. Lastly the country was renamed from The United Provinces of Plagosi to The United Plagosi Provinces of the Osterium.

Peace however didn't last long and on The 26th of October 2022 Yamato of Celastris declared Hollenkreis a rebellion, declared war on them and exiled them from The U.P.P.O.. the main reasons being due to them threatening to annex The U.P.P.O. town of Castra-Fulmen as well as attempting to get Simulami to make them a seperate independent vassal.

On the 28th of october 2022 The U.P.P.O. allowed their M.R.C. vassal to regain independence upon their request however later that day The M.R.C. leader would lead a raid against The U.P.P.O. capital of Urcastle resulting in The U.P.P.O. declaring war against their former vassal. Later that day The M.R.C. would ally Hollenkreis and call The Yurian Shogunate plus Dualfinia into the war against The U.P.P.O.. The U.P.P.O. would break of their non agression pact with Dualfinia due to considering that Dualfinia had broken it due to backing up The M.R.C.. The war however wouldn't last long due to The U.P.P.O. signing a annexation treaty with a Yamato royal loyalist coup that had taken over complete control of The M.R.C. which then resulted in The M.R.C. being fully annexed by The U.P.P.O. on the 28th of october 2022.

Dualfinia would however go onto host The M.R.C. government and publicly denounce The U.P.P.O. deeming them foreign invaders and declaring war on The U.P.P.O.. This resulted in The U.P.P.O. calling in Grand Castell-Llozhar and volkard as allies which caused Dualfinia to pull out of the war completely.

The Yurian Shogunate however was still in the war against The U.P.P.O. along with what remained of loyalist M.R.C. however Yamato of Celastris conducted secret talks with The Yurian Shogunate and found out that The M.R.C. had misinformed their allies regarding the war. After Yamato explained that the war was triggered after The M.R.C. leader had lead a raid against The U.P.P.O. capital the pair signed a non aggression pact on the 31st of October 2022 officially ending The M.R.C. - U.P.P.O. war. Finally as a sign of good faith Yamato signed a guarantee of independence with The Yurian Shogunate and supported them in gaining full recongised independence which resulted in the pair becoming close and Yurian Shogun Nagisa Yamato inviting Yamato to their wedding on the 12 of november 2022. From The 1st - 3rd of November Simulami publicly pledged their support to The U.P.P.O. against The Hollenkreis rebellion which had decided to reform Plagadonia and conducted peacetalks between The U.P.P.O. and Plagadonia. Plagadonia argued to Simulami that The king of The U.P.P.O. Yamato of Celastris had declared them a rebellion for no valid reason other than to exercise his power and The U.P.P.O. government | Mori argued that Hollenkreis had been declared a rebellion post a government vote what all 9 members of Mori had voted in agreement on based on treason grounds. Mori presented evidence to Simulami showing that they had threatened U.P.P.O. towns with annexation, stated "I don't care what The U.P.P.O. says they have no authority over our lands", tried to get Simulami to make them an independent vassal as well as tried to get The provinces of Amberia and Fearg in open rebellion against The U.P.P.O.. Peace talks ended on the 3rd of November with Plagadonia attempting to get Simulami to make them a seperate independent vassal resulting in Simulami commiting full force and siding with The U.P.P.O. against Plagadonia causing a Plagadonia surrender.

Government:
The old Amberian-Urcastle Commonwealth was governed by its The Amberian-Urcastle Commonwealth constitution and laws.

On the 11/10/22 a new constitution was published after agreement from The King of The U.P.P. Yamato of Celastris and Mori.
