The Romans, who ruled the region of Castilla y León for two hundred years, were the first to cultivate vineyard. However, it was later, in the period of the Visigoth domination, when monastic orders improved the wine-production process and art and its related culture throughout the region.
Due to Rueda location at the border territories claimed by both Christians and Muslims, its lands tended to remained deserted and not cultivated, lacking population to establish farms and harvest crops. King Alfonso VI decreed in the 11th century that every person who cultivated vineyards in the area would be considered as its owner. Thanks to this measure and to the proximity of the region to the several cities which acted as capital cities of the kingdom, the wine production and trade increased significantly, establishing the seed for what would later become the Designation of Origin Rueda.
