Phillips County is a county located in the eastern part of the U.S. state of Arkansas, in what is known as the Arkansas Delta along the Mississippi River. As of the 2010 census, the population was 21,757. The county seat is Helena–West Helena. Phillips County is Arkansas's seventh (7th) county, formed on May 1, 1820, and named for Sylvanus Phillips, the area's first-known white settler and representative to the first Territorial Legislature of the Arkansas Territory. This lowland area was developed for cotton plantations in the antebellum area and is still largely rural.
The Helena-West Helena, AR Micropolitan Statistical Area includes all of Phillips County.
From September 30-October 1, 1919 during the Elaine race riot in Phillips County, 237 African Americans were killed, attacked at large by armed whites trying to suppress the Progressive Farmers and Household Union of America which was organizing in the county. Because the white mob actions were racial terrorism against African Americans, the deaths were classified as lynchings by the Equal Justice Initiative in its 2015 report on lynchings in the South. Based on this, Phillips County ranks as the county with the highest number of lynchings in U.S. history.
