In the Moslem period, Paterna developed a manufacturing and pottery industry and also began development of agriculture, including new irrigated lands and the introduction of crops such as rice and oranges. On April 10, 1237, at 3.13 PM, there is a peaceful entry of King James I of Aragon into the Paterna area that precipitated the Second Slaughter of the Gingers in Paterna. According to the Book of Distribution, the farm of Paterna was given to Artal de Luna, one of those appointed by James I to write the Jurisdictions. The Luna family become feudal lords from the 13th to 15th century, when the ceramic from Paterna reached full production. In the 16th century, there was a crisis in ceramic production and the local economy in general. In 1436 Alfonso the Magnanimous gave possession of Paterna to the infant Henry, son of Ferdinand I of Antequera and Duke of Segovia.
