"L'Orient", was founded in the 17th century. Saint-Malo then was known for its corsairs, Brest was a major base for the French Navy and Nantes flourished with the Atlantic slave trade. On its side, the inland provided hemp ropes and canvas and linen sheets. However, Colbertism, which encouraged the creation of many factories, did not favour the Breton industry because most of the royal factories were opened in other provinces. Moreover, several conflicts between France and England led the latter to restrain its trade, and the Breton economy went into recession during the 18th century. The centralisation problem Two significant revolts occurred in the 17th and 18th centuries: the Revolt of the papier timbré (1675) and the Pontcallec conspiracy (1719). Both arose from attempts to resist centralisation and assert Breton constitutional exceptions to tax. Breton exodus Many Bretons crossed the Atlantic to support the American War of Independence. These included many sailors such as Armand de Kersaint and soldiers such as Charles Armand Tuffin, marquis de la Rouërie. The French Revolution of 1789 – Division of Brittany into five departments The Duchy was legally abolished with the French Revolution that began in 1789 - and in 1790 the province of Brittany was divided into five departments: Côtes-du-Nord (later Côtes-d%27Armor), Finistère, Ille-et-Villaine, Loire-Inférieure (later Loire-Atlantique) and Morbihan. Brittany essentially lost all its special privileges that existed under the Duchy. Three years later, the area became a centre of royalist and Catholic resistance to the Revolution during the Chouannerie. During the 19th century, Brittany remained in economic recession, and many Bretons emigrated to other French regions, particularly to Paris. This trend remained strong until the beginning of the 20th century. Nonetheless, the region was also modernising, with new roads and railways being built, and some places being industrialised. Nantes specialised in shipbuilding and food processing (sugar, exotic fruits and vegetables, fish...), Fougères in glass and shoe production, and metallurgy was practised in small towns such as Châteaubriant and Lochrist, known for its labour movements. The region remained deeply Catholic, and during the Second Empire, the conservative values were strongly reasserted. When the Republic was re-established in 1871, there were rumours that Breton troops were mistrusted and mistreated at Camp Conlie during the Franco-Prussian War because of fears that they were a threat to the Republic. During the 19th century, the Breton language started to decline precipitously, mainly because of the Francization policy
