Dublin was established in 1854 by A.H. Dobkins and named in 1860. The name, originally spelled Doublin, is said to have been a practice by early settlers who "doubled in" their wagons to escape attacks. Another version says the town was named after the capital of Ireland. In 1881, the town moved four miles to a site owned by J.D. Bishop in order to be near the newly-laid Texas Central Railroad. Dublin is known primarily for peanut crops and dairy farming, but it is also supported by beef, feed and fertilizer.
In Erath County, the city is 72 miles southwest of Fort Worth and 45 miles northeast of Brownwood. Hunters take deer, duck, dove, and quail in season.
