United States of Earth (Celestial Ascendance)

The Earth Empire was a sovereign state that covered nearly all of Eurasia and large parts of Sinica, Africa and Oceania. Declared by Kuvira Laghima in 1990, at its height, the "empire" was by far the largest state in world history, as well as the most populous one. Despite its name, the nation was not ruled by an emperor and was a nation with many political freedoms and a paragon of human rights.

The state was intended to govern the entire world, but ultimately Kuvira surrendered herself after coming to a realization. If it had been succesful, the nation would have been known as the United States of Earth, with a democratically elected President as its leader.
