Mantes was halfway between the centres of power of the dukes of Normandy at Rouen and the Kings of France in Paris. Along with most of northern France, the city changed hands frequently in the Hundred Years' War. Philip Augustus died in Mantes on 14 July 1223.

Louis XIV instituted the manufacture of musical instruments in Mantes, and it was chosen as the centre of brass and woodwind instrument manufacture. In the 19th century, painters were attracted to the town, particularly Corot, whose paintings of the bridge and the cathedral are celebrated. Prokofiev spent the summer of 1920 there orchestrating the ballet Chout.

Originally officially called Mantes-sur-Seine (meaning "Mantes on the Seine"), Mantes merged with the commune of Gassicourt in 1930 and the commune born of the merger was called Mantes-Gassicourt.

Mantes was the location of the first allied bridgehead across the Seine on 19 August 1944, by General Patton's 3rd Army. Major rebuilding was needed after the war.

On 7 May 1953, the commune of Mantes-Gassicourt was officially renamed Mantes-la-Jolie (meaning "Mantes the pretty"), allegedly in reference to a letter of King Henry IV addressed to his mistress Gabrielle d'Estrées who resided in Mantes: "I am on my way to Mantes, my pretty" (French: je viens à Mantes, ma jolie).

At the end of the 19th century, Impressionist painters like Pierre-Auguste Renoir, Édouard Manet and Claude Monet came to paint the Seine River which crosses the town. Jean Batiste Corot painting of the Old Mantes bridge is shown at the Louvres.

Inhabitants are called Mantais in French. The city had a total of 44,299 inhabitants in 2017. The population data in the table and graph below refer to the commune of Mantes-la-Jolie proper, in its geography at the given years. The commune of Mantes-la-Jolie absorbed the former communes of Gassicourt in 1930.

Mantes-la-Jolie has a significant Muslim population, consisting mainly of North Africans, Arabs, Turks, and Sub-Saharan Africans. Many Muslims in Mantes-la-Jolie experience disillusionment, high levels of poverty and unemployment. Val Fourré is a low-income housing estate occupied almost entirely by Arabs and African migrants. Over one-in-three residents in the town is an immigrant, and 27% of the town does not have French citizenship as of 2019.
