Pike County is said to be the home ofMomo (The Missouri Monster). The first reported sightings in the 1970s were traced to various locations throughout the county.
The first settler, other than Native Americans, was William Spencer who arrived in 1799. Spencer came for a salt spring now known as Spencer Lick, to start a salt-manufacturing business. The salt was made to be shipped to St. Louis, a new but growing town at the time. Spencer abandoned his business when unfriendly Native Americans became a threat to his safety. He relocated the enterprise to Ralls County.[4]
The history of Pike County is complicated by the fact that at its establishment in 1818, it included today's county boundaries, plus all counties north of it and those counties bordering all of them to the west, a total area of over six or seven times larger than its current size and thus covering most of the northeastern border area of today's state of Missouri. Pike County was gradually reduced in size by the creation of Ralls County and subsequent new counties, including Marion, Lewis, Clark, Scotland, Knox, Shelby, and Monroe.[citation needed]
The county was first settled by migrants from the Upper South. Some, though not all, were sympathetic to the Confederate cause in later decades. After the end of the post-Civil-WarReconstruction era, some of the county's inhabitants enforcedJim Crow laws and racial segregation in the county to maintain what has been labeled by some as "white supremacy". This occurred despite the fact that key US/Unionist military operations to control "Confederate" upstarts were launched from Pike County and had bases there.[citation needed]
Five African Americans were tragicallylynched in Pike County between 1883 and 1921.[5] Among those were Curtis and Sam Young, who were both lynched for allegedly murdering the city marshall, Walter Meloan, on June 6, 1898, inClarksville,[6] a small town on the Mississippi River.[7] Pike tied withHoward County, Missouri for the highest number of lynchings of African Americans in the state during this historical period.[8]
