Kingdom City has its origins in the building of US Route 40 in 1925, at the same time US Route 54 was being planned with the intention of intersecting US 40 somewhere along the route. The city ofFulton had hoped for US 40 to go from Columbia through Fulton and intersect US 54 in their city, but the final decision had the highways intersect in what would become Kingdom City, which was then just a rural farm and forested area south of McCredie. McCredie residents fought so hard for the highway that they staged a parade through the heart of Fulton with banners that read "54-40 or Fight". When the road was being built and huge numbers of workers were brought in to do the work, McCredie became a boom town, with future Kingdom City receiving its first gas station and a two-story hotel, which burned down in 1930. Since the area had no name at the time the intersection was referred to only as the "Y", with people in Fulton wanting to name it "North Fulton" and the people in McCredie naming it "South McCredie". The Kingdom Oil Company, owned by B.P. Beamer, suggested Kingdom City, in reflection of the nickname for Callaway County. Through the 1920s and 30s numerous dance halls, restaurants, cafés, and hotels would come and go in Kingdom City. In 1965, Gasper's opened for business. In 1970, the McCredie Post Office moved to Kingdom City and took the community's name. This was the same year Kingdom City incorporated as a village and included the former unincorporated community of McCredie. The Richland Christian Church was listed on the National Register of Historic Places in 2001.
