[6] Founded in 1852 as "Las Moras" (the name of a nearby spring and the creek it feeds), the town initially was a supply stop on the old San Antonio-El Paso road and a supply depot for the U.S. Army's Fort Clark (the fort was established the same year).

In 1873, when a post office was awarded, "ville" was appended to the name to differentiate it from another town.

The town grew quickly through the 19th century with the expansion of the garrison at Fort Clark for the Indian Wars.

For many years, it was the base of the famous Buffalo Soldiers, made up of African Americans.

During the slavery years, they had been living in a settlement in northern Mexico to escape US conditions.

After the Buffalo Soldiers moved out of Fort Clark with the waning of the Indian Wars, it was used as a cavalry post.

Virtually every cavalry unit in the U.S. Army was stationed at or trained at Fort Clark at one time or another.

The resort is not the economic engine the fort once was, and Brackettville has shrunk from its peak population during the war years.

Texas State Highway 131 runs south from Brackettville 45 miles (72 km) to Eagle Pass.

Brackettville has a humid subtropical climate (Köppen Cfa) bordering on a hot semi-arid climate (Köppen BSh) with hot summers, mild winters, and variable but moderate rainfall.

As of the 2020 United States census, there were 1,341 people, 568 households, and 346 families residing in the city.

The climate in this area is characterized by hot, humid summers and generally mild to cool winters.
