History

Formed in 1813 from New Madrid County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Arkansas County was created in 1813 from New Madrid County, initially encompassing parts of present-day Arkansas and a small area of Texas. In 1819, the county lost territory to the creation of Clark, Hempstead, and Pulaski counties, and later to the Quapaw Indian Reservation. Through the 1820s, Arkansas County continued to change boundaries, losing land to the creation of Phillips, Chicot, Jefferson, and Monroe counties, while gaining territory from the Quapaw Indian Reserve in 1827.

Boundary changes from the Newberry Library, Atlas of Historical County Boundaries; the 5 that matter most are shown first.
