Clark County was founded on December 15, 1818, as part of Missouri Territory. One of the original five counties composing Arkansas Territory when the territory was established in 1819, Clark County included all or parts of at least fifteen counties in present-day Arkansas and parts of six counties in what is now Oklahoma. The county was named for Missouri territorial governor William Clark of the Lewis and Clark Expedition.
The county is part of two of Arkansas’s natural regions-the Ouachita Mountains and the Gulf Coastal Plain-and its physical characteristics made the area ideal for farming and hunting. Before Europeans arrived, Native Americans, particularly the Caddo, inhabited the land containing heavy forests, abundant game, rich soil, clear streams, and salt. Archaeological evidence attests to the lengthy presence of the Indians in the area. For more history, you can visit The Encyclopedia of Arkansas History & Culture.
