Kentucky is a state located in the East Central United States, normally included in the group of Southern states, but sometimes partially included, geographically and culturally, in the Midwest. Kentucky is one of four U.S. states established as a commonwealth. Originally a part of Virginia, in 1792 it became the 15th state to join the Union.
In the Great War, Kentucky was again invaded by two US armies, one commanded by George Custer and the other by John Pershing. Between the two, the state was completely overrun, and after the war it was returned to the United States. The US Army and Kentucky State Police endured a tense occupation both during and after the war as both Confederate diehards and socialists resisted their authority.
Kentucky voted to return to the CS under the plebiscite in 1940. The Richmond Agreement stipulated that it would remain demilitarized until 1965, but Featherston violated this term of the agreement and gathered a massive army, which used Kentucky as a springboard for Operation Blackbeard.
In 1943, US forces under General Irving Morrell forced the Confederates back into Kentucky and quickly pushed their way through the state, readmitting it to the Union later that year (albeit under martial law indefinitely). An intractable Confederate resistance movement quickly came into existence.
