The commonwealth of Mushroom Nations is a commonwealth of realms that are their own nations with their own Chancellor's but serve under the same Monarch, King Toadstool. The Chancellor's are the heads of government in each Commonwealth realm but the Monarch is the Head of State.
The commonwealth of Mushroom Nations was established on July 4, 1976 when the 13 Mushroom Colonies of the Kingdom of United Creatures declared independence from the KUC. Usually a commonwealth realm is formed by the Mushroom Kingdom helping a territory of another nation who wants to become an independent nation, become an independent nation.
