 Until it was officially named, Murfreesboro had been referred to as "Forks of the Missouri" or "Three Forks".Much of the county's documented history was destroyed in the court house fires of 1855 and 1895.During the Civil War, Pike County men formed two full companies for service in regiments formed in Montgomery County, in the Confederate Army, with the most active being the 4th Arkansas Infantry, and the county was firmly in support of the Confederate States of America.
