Prior to the advent of white settlers in 1846, Lithia had been variously inhabited by Native American tribes, such as the Tocobaga, Muskogan (Creek), Tomokan, Caloosa, some of whom were mentioned by the Spanish in the 1600s, and later the Seminole. Settlers from Georgia arrived in 1847. In 1848, James Alderman created a ford on the Alafia River at the site of present-day Alderman's Ford Park. By the time of the Civil War, Alderman's cattle ranching operation ran to around 30,000 head of cattle. Around 1900, lithium was discovered in the waters of a spring (now known as Lithia Spring Major), which resulted in the naming of the community to "Lithia".
