The Phoenicians, one of the first great maritime trading cultures, founded the city of Gadir (modern Cádiz) on the coast of southern Spain around 1100 BCE and established the value of viticulture and wine as a commodity in Andalucía.
The wine trade of the eastern Mediterranean owes a significant debt to Phoenician ships: the grapes they carried from the Middle East to North Africa, the Mediterranean islands and the Iberian peninsula represent the genetic ancestors of some of the modern varieties of Spain. However, while the Phoenicians may have introduced viticulture in Spain, evidence of primitive grape cultivation reaches thousands of years back in time, and wild grapes preceded mankind in the region. Winemaking continued under the Romans, who improved on the fragile, large amphorae in use, but it remained a secondary pursuit under the conquering Moors, whose religion forbade the consumption of alcohol. Still, grapegrowing persisted and was often used for raisins and distillation for medicines, perfumes, and other goods. Despite the indifference of the Moors—the sale of wine was illegal, but often tolerated—Spanish wine became renowned for its strength, and found its way as a blending component into wines from France and Italy. During this time, the Catholic church began to expand slowly as well and would soon come to reign in Spain. In 1492, Christopher Columbus and the Spanish explorers opened up a new world for Spanish trade. Wine benefitted greatly from these related occurrences: with the law’s renewed approval, Spanish wine went forth with Spanish ships to supply the nation’s new colonies, and the inherently heavy wines were often made in a deliberately rancio style, or they nonetheless arrived in the West Indies that way.

In this case of Rioja, Monastrell = Mouvedre, like in Jumilla. It is 'experimental' in Rioja because its natural home is in the Levant & La Mancha. It can also be known as Mataro in spain (like is used in australia).
Graciano has been confused for Monastrell in the vineyard in the distant past, but is called Monastrell Menudo or Monastrell Verdado, and would be found in Languedoc as "Morrastell". It was probably the work of Ampelographers who finally helped them figure this all out (such as was the case with Carmenere being mistaken for Merlot in Chile, etc etc).
Graciano is it's own grape with freshness and bright aromatics needed to fine tune the classic Rioja profile. Monastrell on the other hand typically has high alcohol and tannins and big black fruit characteristics.
