Under Charlemagne, a donjon was built in the north-west of the town, on a chalk promontory, (nowadays the site of the Prieuré). It was here, in 774, that Desiderius, king of the Lombards, was held prisoner by Charlemagne, giving the town its name (in French, Didier).
The first church was built near the castle by Heldwide, around 948, the wife of Hilduin 1st of the house of the Counts of Montdidier]
In 1184, King Philip II of France had the outlying buildings of the town burnt down, during the war for the possession of the Amiénois and the Vermandois. In 1195, the town was granted its communal charter.
Under the Ancien Régime, Montdidier was in the province of the Santerre (one of eight provinces of Picardy) and the seat of a bailiwick (established in 1516)
By edict of 1575, Henry III of France created the élection of Montdidier, granting tax-raising powers to elected representatives.
The year 1590 saw the commune threatened and eventually invaded by the troops of Henry IV of France.
As with many towns of the region, Montdidier bore the brunt of the fighting of World War I. Many of the town's more ancient and valuable monuments were destroyed in that occasion.
