History
The county originally covered much of present-day Alabama and Mississippi, and St. Stephens served as the capital of Alabama Territory. Earlier county seats were McIntosh, Wakefield, Rodney, a site near Millry, Barryton and New St. Stephens. The Chatom courthouse was dedicated in 1965. The MOWA Band of Choctaw Indians lives in the southern part of the county and was formally recognized by Alabama in 1979 [1].
Economy
Agriculture and timber drove the early economy, and turpentine from pine forests was a major cash crop. Salt domes discovered in the early 1950s near McIntosh led to salt mining and chemical production, and natural gas found in the early 1970s led Phillips Petroleum to build a refinery. Olin Corporation has produced chemicals in the county since 1952, and timber remains the main industry [1].
Geography and attractions
The county lies on the Coastal Plain, with the Tombigbee and Escatawpa rivers as major waterways. St. Stephens Historical Park covers 200 acres with a 90-acre quarry lake, and Washington County State Lake offers fishing and boating. The Washington County Museum is in the Chatom courthouse basement, and the school system oversees eight schools [1]. See Rivers of Alabama.

Salt mining and chemical production began near McIntosh in the early 1950s, and Olin has produced chemicals there since 1952. Natural gas found in the early 1970s led Philips Petroleum to build a refinery. Timber remains the main industry.
