Kingdom of Osterium

The Amberian-Urcastle Union was a short lived political union in-between The Kingdom of Amberia and The Duchy of Urcastle which was considered a breakaway state from The O.P.T.C. for it's entire lifetime.

Founding:
In march 2022 The Kingdom 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 RHK249 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.
