Kingdom of Osterium

The United provinces of Plagosi is a country in plagos currently lead by The Duchy of Urcastle and was a commonwealth in-between The Duchy of Amberia and The Duchy of Urcastle until Amberia rebelled after a Commonwealth parliament vote failed regarding a merge with Seahaven.

First Founding
In march 2022 The Duchy of Amberia had launched a revolt against it's overlord The O.P.T.C. swearing loyality 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 genral Edd. During this time The O.P.T.C town of Urcastle would become 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 released publically and inforced on The 11th of June 2022 resulting in The union's collapse despite Amberian calls for it to remain.

The Kingdom of Amberia was re-intergrated into The O.P.T.C. and renamed to The O.P.T.C. 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 by The O.P.T.C.

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 18/08/2022 for it's protection due to instablity in The O.P.T.C..

Gaining Freaktown
On the 18/08/2022 The Grand Duchy of Urcastle agreed with The O.P.T.C. Town of Freaktown's owner Jumpercali that Freaktown would offically join The Grand Duchy of 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 defacto O.P.T.C. government after gaining control over the majority of O.P.T.C. lands. The Duchy of Urcastle would also become The defacto government of The Commonwealth due to low Duchy of Amberia governance, During this time Commonwealth leader Yamato of Celastris 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 Commonwealth leader Yamato of Celastris declaring war against The rebels on the 30/08/2022. After declaring war The rebels quickly surrendered resulting in NiuewLyonesse being integrated into Urcastle.

From the 2nd-4th of September 2022 leader Yamato of Celastris would lead a split heated parliament debate with Fearg and Amberia in The Commonwealth parliament which resulted in a Duchy of Urcastle victory resulting in The O.P.T.C. province of Fearg officially joinning The Commonwealth as an intergovernmental government 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 Commonwealth parliament. This was all passed despite Amberia disagreement about Fearg becoming an intergovernmental government province due to Amberian wishes to annex the province directly.

On the 05th of September 2022 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 The Commonwealth parliament and The leader of Amberia Parrotcraft123 pressured him to after The O.P.T.C. threatened to declare The Commonwealth rebels and trigger a Simulam i 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 The O.P.T.C. leader Siam_Man threatened to remove Amberia 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 of Celastris 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 of Celastris already had as well as the promise that Urcastle wouldn't be broken up. This deal was however 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 populus 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 more on their deals.

The Commonwealth would go onto annex Hollenkries on the 1st of October 2022 after they willingly and peacefully joined The Commonwealth. This joining granted Hollenkries 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 by Yamato of Celastris and Jared Von Mafiafell.

On the 3rd of October 2022 after Yamato of Celastris conducted talks with litlkoala the premier of corodova. The Maritime Republic of 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 The Duchy of 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 reponse. The Commonwealth was then temporary re-named to The Commonwealth Parliament Loyalists.

On the 8th of October The Duchy of 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 was also willingly integrated into The U.P.P..
