The unit was created in February 1937 on the
Jaén-
Granada front from the "Granada" and "Maroto" battalions, as well as
confederal militia forces from the
Noalejo sector. The command of the new brigade fell to
Enrique García Moreno, while the command of the General Staff was entrusted to José Gavilanes Verea. In April the 80th Mixed Brigade was assigned to the
21st Division; By then it had its headquarters in
Jaén and covered the
Frailes-Mures-Charilla sector. García Moreno was briefly replaced in June 1937 by
Antonio Gallego Abril, and shortly after by
Carlos Cuerda Gutiérrez. He held command of the unit until January 20, 1938, when he was replaced by Manuel Galván Rodríguez. In May 1938, one of the unit's battalions was sent as reinforcement to the
Levante front, being replaced by another battalion made up of recruits. In October, it was relieved of its positions by the
106th Mixed Brigade, with the 80th Mixed Brigade being subjected to a reorganization in the
Martos and
Torredonjimeno area. In November, it was scheduled to participate in an attack against
Granada, but the operation was eventually thwarted and instead it participated alongside the
78th Mixed Brigade in an attack against the Tózar-Limones sector — which resulted in the near destruction of its 3rd battalion. It remained on the Andalusian front until the end of the war. == Controls ==
