Rhea County

Rhea County is an administrative division in eastern Tennessee situated between the Tennessee River and Walden Ridge. The area spans approximately 336 square miles of land and water.

The county was established in 1807 and named after John Rhea, a politician and veteran of the American Revolutionary War. The area became an important part of Tennessee's early development during the nation's formative years.

The Rhea County Extension Office provides agricultural education, family sciences programs, and youth development initiatives throughout the year for local residents.

Visitors can contact the County Election Commission office in Dayton for information on voter services and local administration. The central location provides convenient access for residents and travelers seeking government services.

During the Civil War in 1862, an unusual all-female cavalry unit called the Rhea County Spartans formed in the area. This group represented a rare exception among armed formations of that era.
