Together with two of her sisters, the ship returned to the Mediterranean the following year, but was assigned to the 2nd Squadron (2e Escadre) in 1911, as the units based in northwestern France had been renamed.

When World War I began in August 1914, Marseillaise was assigned to patrol the English Channel to enforce the blockade of Germany and remained on that duty into 1915.

She was transferred to the French West Indies later that year where she searched for German commerce raiders and escorted convoys for the rest of the war.

Marseillaise had four-cylinder engines fed by 28 Belleville boilers that were designed to produce a total of 20,500 metric horsepower (15,100 kW) intended to give them a maximum speed of 21 knots (39 km/h; 24 mph).

The cruisers carried enough coal to give them a range of 6,500 nautical miles (12,000 km; 7,500 mi) at a speed of 10 knots (19 km/h; 12 mph).

[2] The main battery of the Gloire class consisted of two quick-firing (QF) 194 mm Modèle 1893–1896 guns mounted in single-gun turrets fore and aft of the superstructure.

[6] Marseillaise, named after the French national anthem,[7] was authorized in the 1898 Naval Program and was ordered from the Arsenal de Brest on 19 June 1899.

By September 1905, she was flagship of Rear Admiral (Contre-amiral) Paul Campion, commander of the squadron, and remained as such until she was briefly placed in reserve in July 1907.

[9] Marseillaise was recommissioned in January 1908 as the flagship of Rear Admiral Thierry, commander of the 2nd Cruiser Division of the Northern Squadron.

[11] After the eastern entrance to the Channel was sealed off with anti-submarine nets and minefields in 1915, the armored cruisers were no longer required and Marseillaise had been sent to the West Indies by 1916.

After another reorganization in May, the ship and all of her sisters were assigned to the 3rd DL which was tasked with patrolling the West Indies in search of German commerce raiders.

The ship was assigned to the Atlantic Division in March 1920 and was part of the escort on 29 June for the ocean liner SS George Washington as she ferried President of the United States Woodrow Wilson from Europe to the US.

She was stricken from the naval register in 1929; the ship was renamed Marseilles II on 13 February 1932, condemned that same day and was scrapped at Brégaillon in December 1933.
