[1] After the defeat of Napoleon at the Battle of Leipzig in 1813 the royal family returned to Turin and the re-building of the Sardinian Army commenced in 1814.

The brigade participated in the First Italian War of Independence fighting in the battles of Santa Lucia, Goito, Pastrengo and Custoza.

Afterwards the brigade, as part of the 1st Division of the Line of the V Army Corps, entered the Kingdom of the Two Sicilies to aid Giuseppe Garibaldi in his Expedition of the Thousand.

Finally the brigade participated in the siege of Gaeta, where the 1st Grenadiers Regiment earned its first Gold Medal of Military Valor.

Arriving on Mount Cengio on 23 May 1916 the Granatieri held the position even after ammunition had been expended and the Austrians breached the brigade's line.

Ultimately the stubborn defense of Mount Cengio ensured that the Austrians could not achieve the aims of their offensive.

In spring 1943 the division was moved to Rome to aid in the defence of the city in case of an Allied attack.

During this time the division was reorganized along the lines of the Mod.43 reform of the Italian Army and was augmented with the XXI Mortar Battalion.

The future Italian president Sandro Pertini brought a detachment of resistance fighters to Porta San Paolo where they received the weapons of fallen grenadiers.

However the Italian soldiers handed thousands of weapons over to the civilian population, which was quick to form an organized resistance movement in the city of Rome.

On 13 September elements of the Free French 4th Moroccan Mountain Division landed in Ajaccio to support the Italian efforts to stop the 30,000 retreating Germans.

However it was decided that the infantry of the division should join the Combat Group "Friuli", which fought already on the allies side on the Italian front.

By 1974 the division consisted of the: During the 1975 army reform the regimental level was abolished and battalions came forthwith under direct command of multi-arms brigades.

The "Granatieri di Sardegna" division remained active for one more year to change from a motorized to a mechanized unit by adding the battalions of the 1st Armored Bersaglieri Regiment and the II Self-propelled Field Artillery Group of the Armored Division "Centauro", before contracting to Mechanized Brigade "Granatieri di Sardegna" on 1 November 1976.

The brigade commanded the following units after the reform was complete:[1] With the end of the Cold War the Italian Army began to draw down its forces and battalions returned to their regimental names for traditional reasons.

After the last round of reforms in 1997 the brigade consisted of the following units: In the following years the brigade was further reduced: on 29 October 2002 the 2nd Regiment "Granatieri di Sardegna" in Spoleto was disbanded and its remaining two mechanized companies came under the 1st Regiment "Granatieri di Sardegna" as 2nd Battalion "Cengio".

[23] As of 4 October 2022 the brigade is organized as follows: The "Lancieri di Montebello" cavalry regiment is equipped with Centauro wheeled tank destroyers and VTLM Lince vehicles.

The personnel of the brigade's units wears the following gorget patches:[24] Every 18 February the brigade celebrates a mass in memory of Don Alberto Genovese, Duke of San Pietro, whose father Don Bernardino Antonio Genovese had founded the Regiment of Sardinia in 1744 and was the regiment's colonel until 1759.
