The regiment’s origins trace back to the 150th Demi-Brigade (1794–1796) and the 150th Line Infantry Regiment (1813–1814), formed by
Napoleon I for the German campaign and disbanded after heavy losses at
Arras in July 1814. A new 150th Infantry Regiment was created on 25 July 1887, continuing the earlier traditions. During the
First World War, the regiment was based in Verdun in 1914. It saw extensive service on the Western Front, fighting at Alsace, the Marne, Champagne, Verdun, and the Somme. The names of soldiers from the regiment who died during the War are recorded in the publication , preserved by the
Bibliothèque nationale de France. In
World War II, it formed part of the
12th Infantry Division and held the French sector of the
Dunkirk perimeter in May–June 1940, fighting until its surrender at
Malo-les-Bains on 4 June after covering the evacuation of
Operation Dynamo. The regiment was briefly re-formed within the
Armistice Army at
Agen in 1940, disbanded in 1942, and later revived within the
Free French Forces at
Verdun in 1944. Reorganised in early 1945, it took part in the liberation of
Royan before again being dissolved the following year. A new 150th Infantry Battalion was created in 1946 and deployed to
Morocco in 1947 before disbanding in 1949. The designation returned in 1963 for a motorised infantry regiment, later converted to mechanised status in 1975. It was disbanded in 1990, briefly revived as a reserve regiment, and permanently dissolved in 1996, ending more than two centuries of intermittent service. == Traditions ==
