Union with the French Crown and modern period

As a result of the Mad War, the Duke Francis II could not have his daughter Anne married without the king of France's consent. Nonetheless, she married the Holy Roman Emperor in 1490, leading to a crisis with France. Charles VIII of France besieged Rennes and had the marriage cancelled. He eventually married Anne of Brittany. After he died childless, the duchess had to marry his heir and cousin Louis XII. Anne unsuccessfully tried to preserve Breton independence, but she died in 1514, and the union between the two crowns was formally carried out by Francis I in 1532. He granted several privileges to Brittany, such as exemption from the gabelle, a tax on salt that was very unpopular in France. Under the Ancien Régime, Brittany and France were governed as separate countries but under the same crown, so Breton aristocrats in the French royal court were classed as Princes étrangers (foreign princes).

From the 15th to the 18th century, Brittany reached an economic golden age. The region was located on the seaways near Spain, England and the Netherlands and it greatly benefited from the creation of a French colonial empire. Local seaports like Brest and Saint-Brieuc quickly expanded, and Lorient, first spelled "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.
