the bourgeoisie, who strove to democratise the Republic. Finally, the term for the historical era is a historiographical invention of 19th-century Dutch historians, comparable to the terms "First Stadtholderless Period", "Second Stadtholderless Period", and "Fransche Tijd (French Era)" (for the era of the Batavian Republic, the Kingdom of Holland and the French First Empire, 1795–1813). Herman Theodoor Colenbrander for instance, used the term as the title of one of his main works: (The Hague, 1897). The term was often used in a pejorative fashion, but lately has acquired a more positive connotation.<ref>Cf.

The absolute size of Dutch GNP remained constant, but the economy was overtaken by that of other European countries in the course of the 18th century. Besides, in a number of economic sectors, such as the fisheries and most industries that had sprung up in the early 17th century, an absolute decline occurred. The country's deindustrialization resulted in de-urbanization as artisans that had worked in the disappearing industries had to move to areas where work was still to be found. The shrinking industrial base was also concentrating in particular areas, to the detriment of other areas where certain industries (shipbuilding, textiles) had formerly been prominent. Remarkably for an era of rapid population growth in other European countries, the size of the Dutch population remained constant during the 18th century at around 1.9 million people, which (in view of the constant absolute size of the economy) resulted in a constant per capita income. But this was somewhat misleading as economic inequality markedly increased during the 18th century: the economy became dominated by a small group of very rich rentiers, and the economy shifted to what we would now call a service economy, in which the commercial sector (always strong in the Netherlands) and the banking sector dominated. These shifts had a devastating effect for the people who experienced downward social mobility and ended up in the lower strata of Dutch society. But even those that were not affected by such downward mobility, and remained in the upper and middle classes, were affected by this perceived economic decline. The economic decline worked through in the
