First United Commonwealth

The United Commonwealth is a union of Nebskoslavia, Gdanyc and Czervoslavia.

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.

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

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