It is part of the Sherman–Denison metropolitan statistical area. The first settlers in the area arrived around the time of the Texas Revolution in 1836. In 1843, the last Indian battle in Grayson County was said to have been fought in the area. The first settlers of Howe were Jabez and Harriet Haning, and Jabez's brother John. They received land through the Peters colony after arriving from Pennsylvania before 1850. When the Houston and Texas Central Railway extended through the area in 1873, a railroad switch was located in the community. It was called "Summit" because, at 810 feet above sea level, it was believed to be the highest point between the Red River and the Gulf of Mexico. In 1873, when Summit received a post office, two businesses were located at the switch—a general store and a saloon. Several houses were built to the east of the switch. Jabez Haning persuaded the railroad to establish a depot on his land by donating every second lot in his newly platted town to the railroad. In 1876, the names of the depot, the store, and the post office were changed to "Howe", after F. M. Howe, who worked for the Houston and Texas Central. Howe had three saloons until around 1900, when the town voted to prohibit the sale of alcohol. Its first one-room school building opened in 1877 and was replaced by a two-story building in 1884.
