Obion County, Tennessee: History
In the year, 1811 there was a large seismic activity located on the New Madrid Fault Line. The series of earthquakes, while devastating, formed Reelfoot Lake.
Obion was later established in 1823 and organized the following year. It was named for the Obion River, which flows through the county and is a tributary of the nearby Mississippi River. The word "Obion" is believed to be derived from a Native American word meaning "many forks", or from an Irish trapper named O'Brien.
The founding of Obion County originally came from the expansion of railroads. The county has since moved towards many agricultural and manufacturing productions.
In 2013, Discovery Park of America opened in Union City. Discovery Park is a 50-acre encyclopedic museum and heritage park with exhibits pertaining to local and national history, military history, art, science, and technology.
