The Star-Journal traces its history to the Warrensburg Journal, which began publishing April 17, 1865, by James Douglas Eads, seven days after the end of the American Civil War and two days after the assassination of Abraham Lincoln. Warrensburg, population of 1,000 at the time, did not have a newspaper. Prior to the war, Eads, a church pastor, had published the Warrensburg Signal. In addition to
his pastor and newspaper interests, he was also a physician and ran a hotel. On Oct. 6, 1876, it became the Journal-Democrat after merging with the Warrensburg Democrat, which had started in 1871. In 1907, Wallace Crossley became the publisher. On Feb. 6, 1913, it became the Star-Journal after merging with the Johnson County Star, founded in 1883 by J.M. William and Avis Tucker bought the paper in 1947. At one point it owned radio station KOKO (1450AM). William Tucker died in 1966 and Avis owned the paper until 2007 when it was sold to NPG. In October 2020, the Sedalia Democrat, a Phillips Media Group newspaper, took over ownership of the Star-Journal. The name was changed from Daily Star-Journal to Star-Journal to reflect the weekly publication.
