Amecanio

Amecanio was an independent state located on Earth, and later became a State of the UEE. It roughly covered the entirety of North America. As it was located in North America and in existence at the time of Unification, it was likely a member of the North American Alliance.

History
A warship called Stanley was registered to Amecanio and rebelled against the formation of the United Nations of Earth. This started the Unification Wars.
