Morgan County was organized in 1833 upon separation from Cooper County. It is named in honor of Revolutionary War General Daniel Morgan. Versailles, with a name referring to the French royal estate near Paris, France, was designated as the county seat and platted in 1854. Established in 1853 there, the Martin Hotel was visited in the post-Civil War period by both showman and circus entrepreneur P. T. Barnum and outlaw robber Jesse James. Listed on the National Register of Historic Places in 1978, it now operates as a museum. In 1858 the Mulhollen Station was a mail stop here for the newly established Butterfield Overland Mail stagecoach line, which carried goods and mail for several years to San Francisco, California. The Morgan County Courthouse in Versailles, which has also been listed on the NRHP, was designed with French-style details, such as a mansard roof, in keeping with the origin of the town's name. It burned in 1887. The majority of the records were rescued, and the courthouse was soon rebuilt and restored. Coal mining was historically an important economic activity in Morgan County.
