For fourteen years, it was the royal domain of King Ladislao of Naples, and in 1420 it was returned again to Nicholas Ruffo, who gave it as part of a dowry for his daughter Enrichetta who was married to Antonio Centelles. After a rebellion by the rural people, King Alfonso V of Aragon took control of the city. In 1460 there was a war with the partisans of Centelles. When peace returned, the city was granted new privileges which greatly promoted the development of its silk industry, for which its damasks were known throughout Europe. From this time forward, Catanzaro firmly established itself as an import center for its textile productions. In the XV century, Catanzaro was exporting both its silk cloth and its technical skills to neighbouring Sicily. By the middle of the century, silk spinning was taking place in Catanzaro, on a large scale. In 1466, King Louis XI decided to develop a national silk industry in Lyon and called a large number of Italian workers, mainly from Calabria. The fame of the master silk weavers of Catanzaro spread throughout France and they were invited to Lyon in order to teach the techniques of weaving. In 1470, one of these weavers, known as Jean le Calabrais, invented the first prototype of a Jacquard-type loom. He introduced a new kind of machine which was able to work the yarns faster and more precisely. Over the years, improvements to the loom were ongoing. In 1519 Emperor Charles V formally recognized the growth of the industry of Catanzaro by allowing the city to establish a consulate of the silk craft, charged with regulating and check in the various stages of a production that flourished throughout the sixteenth century. At the moment of the creation of its guild, the city declared that it had over 500 looms. By 1660, when the town had about 16,000 inhabitants, its silk industry kept 1,000 looms, and at least 5,000 people, busy. The silk textiles of Catanzaro were not only sold at the kingdom's markets, they were also exported to Venice, France, Spain and England. In 1528 Charles V gave authorization for Catanzaro to bear the imperial eagle attached to a coat of arms depicting the hilltops of the town. On 23 December 1961, at the Fiumarella viaduct near Catanzaro, there was a serious rail accident, when a train derailed and fell about into the river
