About Owners
Messageries Maritimes (MM, Compagnie des), Paris

The shipping side of the government-owned 'Messageries Nationales' was split in 1852 under the name 'Compagnie des Services Maritimes des Messageries Nationales' and by 1857 it owned 57 ships.

In 1871, the company became 'Compagnie des Messageries Maritimes'. In 1904 the fleets of Compagnie Francaise de l'Est Asiatique and Compagnie Nationale de Navigation were taken over.

After WWII, only 21 ships were left. However the fleet was rebuilt, but the independence of French colonies caused the whole passenger fleet to be disposed of.

In 1977 MM and CGT (French Line) were amalgamated under the name Compagnie Generale Maritime.
