The Valencian economy recovered during the 18th century with the rising manufacture of woven silk and ceramic tiles. The silk industry boomed during this century, with the city replacing Toledo as the main silk-manufacturing centre in Spain. The Palau de Justícia is an example of the affluence manifested in the most prosperous times of Bourbon rule (1758–1802) during the rule of Charles III. The 18th century was the age of the Enlightenment in Europe, and its humanistic ideals influenced such men as Gregory Maians and Pérez Bayer in Valencia, who maintained correspondence with the leading French and German thinkers of the time.
