The Tennessee Historical Commission (THC) is the State Historic Preservation Office for the U.S. state of Tennessee. Headquartered in Nashville, it is an independent state agency, administratively attached to the Department of Environment and Conservation. Its mission is to protect, preserve, interpret, maintain, and administer historic places; to encourage the inclusive diverse study of Tennessee's history for the benefit of future generations; to mark important locations, persons, and events in Tennessee history; to assist in worthy publication projects; to review, comment on and identify projects that will potentially impact historic properties; to locate, identify, record, and nominate to the National Register of Historic Places all properties which meet National Register criteria, and to implement other programs of the National Historic Preservation Act of 1966 as amended. The Tennessee Historical Commission also refers to the entity consisting of 24 Governor-appointed members and five ex officio members.
The Commission was originally established as the "Tennessee Historical Committee" in January, 1919. Its initial purpose was to memorialize events pertaining to World War I. In 1921 an amendment to the Act that created the Committee expanded its duties toward its modern mission, designating that the Committee could "care for the proper marking and preservation of battlefields, houses, and other places celebrated in the history of the state." After a decade of inactivity following the death of its first Chairman John Trotwood Moore in 1929, it was re-energized in 1940 by Governor Prentice Cooper. A partnership with the Tennessee Historical Society began in 1942 to produce the Tennessee Historical Quarterly, which is still published today. In 1951 the historic marker program was founded. Since then, approximately 2,000 markers have been erected across the state. Following the passage of the National Historic Preservation Act of 1966, the Commission was designated as the State Historic Preservation Office (SHPO). There are 29 Commission members, consisting of 24 members appointed by the Governor (8 per Grand Division) and five ex officio members, including the Governor, State Archaeologist, State Librarian, State Historian, and the Commissioner of Environment and Conservation. The Board meets three times a year, usually the third Friday of February, June, and October. As of 2017 the Commission has a professional staff of 16. It administers Federal programs including the National Register of Historic Places, Section 106 review, the Certified Local Government Program, survey, and historic tax credits. State programs include historic markers, state-owned historic sites, and the Tennessee Wars Commission.
