Seine-Maritime (French pronunciation: [sɛn maʁitim] ) is a department of France in the Normandy region of northern France. It is situated on the northern coast of France, at the mouth of the Seine, and includes the cities of Rouen and Le Havre. Until 1955 it was named Seine-Inférieure. It had a population of 1,255,633 in 2019.[3]


1790 - Creation of the Seine-Inférieure department
The department was created from part of the old province of Normandy during the French Revolution, on 4 March 1790, through the application of a law of 22 December 1789.
1815 - Occupation
After the victory at Waterloo of the coalition armies, the department was occupied by British forces from June 1815 till November 1818.
1843 – Railways and industry
In Rouen, Elbeuf, and Bolbec, the number of textile factories is increasing. Metallurgy and naval construction as well.
1851 - A republican department
Following President Louis-Napoléon Bonaparte's 1851 Coup d'état, Seine-Inférieure was one of several departments placed under a state of emergency (literally, in French, state of siege) [4] following fears of significant resistance to the new government.
World War II
In 1942, during occupation by Nazi Germany, two Allied raids, the Bruneval and Dieppe, took place at towns of the channel coast of Seine-Inférieure.
1955 - Rename to Seine-Maritime

In 1955, the department's name was officially changed to Seine-Maritime.


The arms of the departement Seine-Maritime are blazoned :
Gules a fess wavy argent between two lions passant gardant or armed and langued azure.


The department can be split into three main areas:[5]


The département was created in 1790 as Seine-Inférieure, one of five departements that replaced the former province of Normandy. In 1800 five arrondissements were created within the département, namely Rouen, Le Havre, Dieppe, Neufchatel and Yvetot, although the latter two were disbanded in 1926. On 18 January 1955 the name of the département was changed to Seine-Maritime, in order to provide a more positive-sounding name and in-keeping with changes made in a number of other French departements.
