First United Commonwealth

The United Commonwealth was a federative nation locate across Syltör, Nieden and Plagos on Rathnir, and Leifmyrr on Eldham.

Founding
The United Commonwealth was created by the marriage of Slout II and Lodomiera Korola. Many didn't quickly recognise the union, and to this day both Czervoslavia and Nebskoslavia often do diplmacy separately, despite being in union.

The United Nations of Plagos
Czervoslavia was a member of the UNP, and the UC subsequently retained the status of a UNP member. Czervoslavia expirienced illegal settlers from Nova Regna, but the issue was swiftly resolved.

Collapse
After threats of Bardonian invasion all member states illegally seceded. Whilst never officially dissolved, the United Commonwealth ceased to function. The Commonwealth Armed Forces eventually transformed into the Korolian Legion.

Government
The Union was headed by all monarchs with equal power. Each constituent nation was split up into voievodeships, each was headed by a democratically elected voievode who make up the Sejm of the United Commonwealth, an institution akin to a parliament. There was a the Provisional Sejm, which is tasked with conjuring a constitution for the United Commonwealth.

Overlapping membership
Nebskoslavia and Czervoslavia were part of Ryzan and Plagetea respectively. This had raised a number of concerns, especially considering that the union has no official status relating to the two other nations.
