The 1st Army Division (Spanish; Castilian: I División de Ejército), formerly the Northern Army Detachment (Spanish; Castilian: Agrupamiento del Norte), is a unit of the Peruvian Army.
First founded as a Region, its headquarters were relocated by Luis Miguel Sánchez Cerro's administration from Lambayeque to Piura in 1930.[2] It was then reorganized under Manuel Prado's administration and renamed as the Northern Army Detachment (Spanish; Castilian: Agrupamiento del Norte) in January 1941, under the command of then General Eloy Ureta.[3] After hostilities broke out with Ecuador on July of the same year, the division took on a major role during the conflict, carrying out an offensive on the Ecuadorian coast.[4] [5]
In the 1960s, the unit was again renamed to the 1st Military Region, and again in 2003 as the Northern Military Region.[2] In 2012, by Legislative Decree No. 1137 “Peruvian Army Law”, the military regions again became army divisions. As a result, the unit's name was again changed to its current one.[2] [6]
The division's coat of arms features a Sun of May and other features that represent certain elements of the division.[7]
