Clark County was first established in 1818, and therefore became one of the five counties in existence at the time Arkansas became a Territory in 1819. The centerpiece of Clark County government has always been its county courthouse. Historically, the county seat is the place where most citizens came into direct contact with government, whether it be to assess personal property, pay real estate taxes, obtain a marriage license, or register to vote.
