Sullivan County is located in the West Central area of New Hampshire and was named after Brigadier General John Sullivan (1740-1795), a Revolutionary War hero. On July 5, 1827, Sullivan County came into being. Prior to its founding, Sullivan County was part of Cheshire county. The Town of Newport was chosen as the county seat as it remains to this day.
