Smyrna is a town in Rutherford County, Tennessee. Smyrna's population was 39,974 at the 2010 census and estimated to be 51,586 in 2019. In 2007, U.S. News & World Report listed Smyrna as one of the best places in the United States to retire.
The town of Smyrna has its European-American roots in the early 19th century and began as an agrarian community. It was important during the Civil War because its railroad station lies between Nashville and Chattanooga. One of the major events of the war for the town involved the Confederate States soldier Sam Davis, who, after being charged with spying, gave up his life instead of giving any information to the Union Army. He was captured November 20, 1863, and was hanged by Union forces on November 27 of that year. The Sam Davis Plantation, located on 160 acres (0.65 km2) of well-maintained farmland, is the town's most important historical site.
Smyrna was originally incorporated in 1869 but its charter was rescinded by the state several years later. In 1915, the town re-incorporated and adopted a commission-mayor form of government.
In 1941 during World War II, Sewart Air Force Base was established here and served as a B-17 Flying Fortress and B-24 advanced training facility. During the 1950s and 1960s, the military personnel and dependents totaled more than 10,000 persons stationed at the base.
