# Decatur County, Tennessee

Decatur County is a county located in the U.S. state of Tennessee. As of the 2020 census, the population was 11,435. Its county seat is Decaturville.

## History

This county is named after naval hero Stephen Decatur, Jr., who gained national recognition in the First Barbary War, the Second Barbary War, and the War of 1812 by his leadership and achievements at sea. The county was created in November 1845 from the part of Perry County west of the Tennessee River in response to a petition by citizens on the west side of the river.
Like several other counties west of the Tennessee River, Decatur County was substantially pro-Union during the Civil War, contrary to the generally pro-Confederate sympathies of West and Middle Tennessee. In Tennessee's Ordinance of Secession referendum on June 8, 1861, Decatur County voted to remain in the Union by a margin of 550 to 310, being one of only eight counties in West or Middle Tennessee to support the Union. Earlier on February 9, 1861, Decatur County voters had voted against holding a secession convention by a margin of 514 to 251.
In 2015, the Decatur County clerk of court and the entire staff of that office resigned, to express conscientious objection to the United States Supreme Court's ruling in Obergefell v. Hodges, which would oblige the office to issue marriage licenses to same-sex couples.

Decatur County – like all of rural Tennessee – is a Republican stronghold.
