Messageries Maritimes (MM)
The Compagnie des Services Maritimes de Messageries National, a state-controlled shipping company, was founded by the French Government in 1835 in order to maintain a liner service between Marseille and the Levant ports in the eastern Mediterranean. With the restoration of the monarchy in France in 1853, the shipping company changed its name to Cie. des Services Messageries Imperiales. During the next five years, the company expanded dramatically and in 1857 had a fleet consisting of 57 passenger and cargo ships. After the end of the Franco-German War in 1871 and the final end of the monarchy, the shipping company was renamed again to Compagnie des Messageries Maritimes (MM).
