The division is heir to the Blue Division which fought during the Franco-Prussian War of 1870, in particular during the Battle of Bazeilles and the 9th Colonial Infantry Division, part of the Free French Forces, which distinguished themselves in the apprehending of Elba in June 1944 and the disembarking in Provence on 15 August of the same year. The Division then made way to Indochina, where it was placed dormant (without being dissolved) in December 1947. The unit was reactivated in July 1963 in Brittany under the designation of 9th Brigade. On 1 January 1976, the division was baptized as 9th Marine Infantry Division 9e DIMa. Accordingly, the division was attached to the terrestrial intervention force, then the Rapid Action Force (FAR) since 1983. On 1 July 1999, the unit was restructured in a brigade and was designated as 9th Light Armoured Marine Brigade (BLBMa). On 1 January 2013, the brigade was named to the current designation as the 9th Marine Infantry Brigade (9e BIMa).
