Ohio is a Midwestern state of the United States, in the Great Lakes region. It was the first state admitted to the Union under the Northwest Ordinance. Ohio has long been a cultural and geographical crossroads in North America. The 34th largest state by area in the U.S., it is the 7th-most populous with nearly 11.5 million residents. The capital of Ohio is Columbus. Ohio is known as the "Buckeye State" for its prevalence of Ohio Buckeye trees, and, as such, Ohioans are also known as "Buckeyes".
In the centuries following the disintegration of United States in the early 1800s, the republic of Ohio was a bitter enemy of its neighbor, Virginia. The two made war on each other several times throughout the 19th, 20th, and 21st Centuries.
In 2097, Ohio launched a new war against Virginia. A few weeks into the war, Ohio disseminated a mutated measles virus among the Virginians and followed through with a ground invasion. It also provided arms to Virginia's disenfranchised blacks. However, after a period of bloody fighting, the war ground to a halt, an armistice was struck, and Ohio withdrew its forces.
