History
Fort Thomas takes its name from General George H. Thomas, a Union Army general, and the city grew up around the U.S. Army post established there in the late 19th century known as the Military Reservation of Fort Thomas. The post played a notable role in American military history, serving as a mobilization site during the Spanish-American War in 1898. Over the 20th century, the former military grounds were gradually transitioned to civilian use, and the city incorporated and developed into the prosperous residential community it is today.

Fort Thomas also gained national attention in 1896 due to the high-profile Pearl Bryan murder case, which remains one of the most sensational criminal cases in Kentucky history.
