The United Britannic Commonwealth (U.B.C.), commonly known as the United Commonwealth (U.C.), is a constitutional monarchy and confederation with territory spanning across the globe. Established in 1876 as the unification of the United Kingdom of Great Britain and Ireland with several of its North American colonies, the United Commonwealth was established as a confederation of three dominions (Acadia, Britain, and Canada), governed by a single Parliament, and with the Monarchy being a united figurehead. The United Commonwealth would expand to include more dominions.
