Over the rest of the 16th century, further protectionist measures were introduced. The height of French mercantilism is closely associated with Jean-Baptiste Colbert, finance minister for 22 years in the 17th century, to the extent that French mercantilism is sometimes called Colbertism. Under Colbert, the French government became deeply involved in the economy in order to increase exports. Protectionist policies were enacted that limited imports and favored exports. Industries were organized into guilds and monopolies, and production was regulated by the state through a series of more than one thousand directives outlining how different products should be produced.
