In 1908, John Closner, William Briggs, Argyle McAllen, Plutarco de la Viña and Dennis B. Chapin developed a new community (the town square of which is now located at the crossroads of U.S. Highway 281 and State Highway 107). The town was named Chapin in honor of one of the developers. It became the county seat of Hidalgo County in a dramatic, nighttime covert operation in which the county records were removed from the previous county seat, Hidalgo, Texas. When Dennis Chapin was involved in the shooting death of Oscar J. Rountree at the Dan Breen Saloon in San Antonio, Texas, the community changed its name to Edinburg to honor John Young, a prominent businessman who was born in Edinburgh, Scotland. The town was incorporated in 1919.
