The State of Missouri, better known as the Missourian Empire, can trace direct legal lineage to Rome. St. Louis, just like Rome, was built on seven hills (you just can't see the seven hills anymore because we built over them). We have a Caesar, Imperator Michaelus Parsonian Augustus. We have two consuls, Joshus Hawlian and Erick Schmittus. Our claims extend as far down as Northern Arkansius, where we conquered the great Missouri Bootheel, named in symbolism of our trampling of the uncivilized Arkansians to our south, known for their inferior gods, Wal-Marr, god of consumerism, and Hickus, god of leaving random, rusted junk in your yard. Our borders are mighty and our history is fierce. We have the greatest claim to Roman heritage simply from the very glory that inhabits our borders.
Also geg Vandals and Goths migrated from Oder and Vistula basin to some warmer climate where they were dissolved by Vvlgar Latin speakers and let SlavGODs into their former lands.
