The department was again abolished from January 1, 1867 to June 24, 1870 during the military occupation and reconstruction of Texas. After Texas was readmitted to the United States on March 30, 1870, the department was reestablished and empowered by the Constitution of Texas to fight unrest and restore order. It comprised the Office of the Adjutant General, Texas militia, and Texas State Police (Texas Rangers). Following the Militia Act of 1903, the Texas militia became the Texas National Guard. During World War I, the Department of Texas was re-designated the Adjutant General Department and again maintained provincial "Home Guard" forces for defense of the state while the Texas National Guard was under federal command. By 1935, the Texas Rangers had evolved from a paramilitary force to a police force and were reorganized under the Texas Department of Public Safety. During World War II, the United States Congress amended the National Defense Act of 1916 permanently authorizing the "Home Guard" defense forces as the Texas State Guard. The Adjutant General Department was colloquially referred to as the "Texas Military" from 2006 to 2015. On October 28, 2015 the Adjutant General Department was officially rebranded as the Texas Military Department.
