Warren County comprises the McMinnville, TN Micropolitan Statistical Area.
Warren County was created in 1807 from a portion of White County, and named for Joseph Warren (1741–1775), a soldier in the American Revolution.  The revised Tennessee State Constitution of 1834 stated that no new county could be within 12 miles (19 km) of the county seat of the county from which it was formed. The boundaries of five counties formed from Warren— Grundy, Van Buren, Cannon, Coffee and DeKalb— were exactly 12 miles from Warren's county seat, McMinnville, giving the county its distinctive round shape. 
Warren County citizens voted to secede from the Union before the American Civil War in February 1861 in a State referendum. However, Tennessee overall decided to remain in the Union in that time. But when Abraham Lincoln demanded that Tennessee provide troops to fight against the Southern state in April 1861, this was viewed as a violation of Article 3, Section 3 of the U.S. Constitution. At a new referendum in June, 1861, Warren County, along with a majority of Tennessee's counties, voted for independence. Unlike some states, slavery was not mentioned as one of the reasons in Tennessee's secession proclamation.  Men from Warren County and surrounding upper Cumberland region formed and served in many units in Tennessee's defense, including the 16th Tennessee Infantry  led by McMinnville, TN resident Col. John Houston Savage. The Confederate monument  next to the county courthouse is dedicated in the memory of the men who served and died in the 16th and lists their names.
Men from Warren County and upper Cumberland area joined the 16th TN Infantry Regiment, among others. This is the flag of the 16th H Company. The flag now resides in the Texas 'Civil War' Museum in Fort Worth TX. http://home.freeuk.com/gazkhan/tenn_battle-flags_h-company.htm.
Warren County was the site of several saltpeter mines. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from several local caves. Hubbards Cave, near Camp Woodlee, was a major operation. Henshaw Cave on Cardwell Mountain (now part of Cumberland Caverns) and Solomon Saltpeter Cave on Ben Lomond Mountain were relatively small mining operations. Most saltpeter mining occurred during the War of 1812 and in the Civil War. 
According to the U.S. Census Bureau, the county has a total area of 434 square miles (1,120 km2), of which 433 square miles (1,120 km2) is land and 1.4 square miles (3.6 km2) (0.3%) is water.  The county lies long the Eastern Highland Rim, near the Cumberland Plateau.
The Caney Fork forms part of the county's borders with White and DeKalb counties to the north. The Rocky River, a tributary of the Caney Fork, forms part of the county's western border with Van Buren County. The Collins River, also a tributary of the Caney Fork, flows through the county, and the Barren Fork, a tributary of the Collins, flows through McMinnville.
Cardwell Mountain is an imposing natural feature located five miles due east of McMinnville. It is an erosional remnant of the nearby Cumberland Plateau. Cardwell Mountain is noted for Cumberland Caverns, an exceptionally long cave which lies underneath the mountain.
