An earlier community known as Fort Dade existed nearby in the 1870s and 1880s, but with the arrival of the railroad, the businesses chose to relocate a few miles to the east to be near the railroad. The newer town became known as Dade City. The name became official when the name of the Hatton post office was changed to Dade City on December 18, 1884.Dade City was first incorporated in 1884 or 1885. That incorporation seems to have been forgotten subsequently, and the city was incorporated again in 1889. When Pasco County was formed from the southern section of Hernando County in 1887, Dade City became the county seat of the new county, first temporarily and later permanently, by a popular vote.
