History of Obion County
In 1811, a series of big earthquakes happened along the New Madrid Fault Line. These powerful earthquakes created Reelfoot Lake.
Obion County was officially started in 1823 and set up in 1824. It was named after the Obion River, which flows through the county. The river is a branch of the nearby Mississippi River. The name "Obion" might come from a Native American word meaning "many forks." It could also be from an Irish trapper named O'Brien.
Obion County first grew because of new railroads. Over time, the county became known for its farming and manufacturing.
In 2013, Discovery Park of America opened in Union City. This is a huge museum and park, covering 50 acres. It has exhibits about local and national history, military history, art, science, and technology.
