The division's lineage begins with the Brigade "Pinerolo" established on 21 December 1821, which on 19 December 1831 split to form the 1st and 2nd infantry regiments under the brigade's command. On 4 May 1839 the two regiments were re-numbered as
13th Regiment Brigade "Pinerolo" and 14th Regiment Brigade "Pinerolo".
World War I The brigade fought on the
Italian front in
World War I. On 10 November 1926 the brigade assumed the name of XXIV Infantry Brigade and received the
225th Infantry Regiment "Arezzo" from the disbanded
Brigade "Arezzo". The brigade was the infantry component of the 24th Territorial Division of
Chieti, which also included the
18th Artillery Regiment. In 1934 the division changed its name to 24th Infantry Division "Gran Sasso".
Second Italo-Ethiopian War The division participated in the
Second Italo-Ethiopian War, where it operated in the
Tigray Region and fought in the
Battle of Shire. After the war the division returned to Italy. On 1 March 1937 the 225th Infantry Regiment "Arezzo" was transferred to the
63rd Infantry Division "Cirene" in
Libya. On 1 March 1938 the 225th Infantry Regiment "Arezzo" was renamed 158th Infantry Regiment "Liguria" and on the same day the 225th Infantry Regiment "Arezzo" was raised anew in
Ascoli Piceno. The 313th Infantry Regiment joined the Pinerolo in Greece in March 1942. While the Pinerolo was on occupation duty in Greece the depot of the 14th Infantry Regiment "Pinerolo" raised on 1 January 1942 the
235th Infantry Regiment "Piceno" for the
152nd Infantry Division "Piceno". The division continued on anti-partisan duty until the
Armistice of Cassibile was announced on 8 September 1943. In the confusion after the armistice the division was the only Italian division in continental Greece to refuse German demands to surrender. The remnants of the division were repatriated to Italy in March 1945. On 15 April 1952 the
Italian Army raised the Infantry Division "Pinerolo" anew. On 1 September 1962 the division was reduced to brigade and it has been active as such since then as
Mechanized Brigade "Pinerolo"). == Organization ==
