Spain in the Middle Ages in the context of "Parias"

The history of Spain dates to contact between the pre-Roman peoples of the Mediterranean coast of the Iberian Peninsula with the Greeks and Phoenicians. During Classical Antiquity, the peninsula was the site of multiple successive colonizations of Greeks, Carthaginians, and Romans. Native peoples of the peninsula, such as the Tartessos, intermingled with the colonizers to create a uniquely Iberian culture. The Romans referred to the entire peninsula as Hispania, from which the name "Spain" originates. As was the rest of the Western Roman Empire, Spain was subject to numerous invasions of Germanic tribes during the 4th and 5th centuries AD, resulting in the end of Roman rule and the establishment of Germanic kingdoms, marking the beginning of the Middle Ages in Spain.

Germanic control lasted until the Umayyad conquest of Hispania began in 711. The region became known as Al-Andalus, and except for the small Kingdom of Asturias, the region remained under the control of Muslim-led states for much of the Early Middle Ages, a period known as the Islamic Golden Age. By the time of the High Middle Ages, Christians from the north gradually expanded their control over Iberia, a period known as the Reconquista. As they expanded southward, a number of Christian kingdoms were formed, including the Kingdom of Navarre, the Kingdom of León, the Kingdom of Castile, and the Kingdom of Aragon. They eventually consolidated into two roughly equivalent polities, the Crown of Castile and the Crown of Aragon. The early modern period is generally dated from the union of the Crowns of Castile and Aragon by royal marriage in 1469.

The Massacre of 1391, also known as the pogroms of 1391, refers to a murderous wave of mass violence committed against the Jews of Spain by the Catholic populace in the crowns of Castile and Aragon in 1391. It was one of the most lethal outbreaks of violence against Jews in medieval Spain, and in medieval European history. Anti-Jewish violence then continued throughout the "Reconquista", culminating in the 1492 expulsion of the Jews from Spain. The first wave in 1391 marked the extreme of such violence.

Under duress, Jews began to convert en masse to Roman Catholicism across the Iberian Peninsula after the massacre, resulting in a substantial population of conversos known as Marranos. Catholics then began to accuse the conversos of secretly maintaining Jewish practices, and of thus undermining the newly united kingdom's nascent national identity. In 1492, the Catholic Monarchs of Spain Ferdinand and Isabella issued the Alhambra Decree, which ordered the expulsion of Jews who had not converted to Catholicism. The resulting diaspora came to be known as the Sephardic Jews.

The Battle of Las Navas de Tolosa, known in Islamic history as the Battle of Al-Uqab (Arabic: معركة العقاب), took place on 16 July 1212 and was an important turning point in the Reconquista and the medieval history of Spain. The Christian forces of King Alfonso VIII of Castile, were joined by the armies of his rivals, Sancho VII of Navarre and Peter II of Aragon, in battle against the Almohad Muslim rulers of the southern half of the Iberian Peninsula. The caliph al-Nasir (Miramamolín in the Spanish chronicles) led the Almohad army, made up of people from all over the Almohad Caliphate.

Navas de Tolosa (also called Las Navas) is a town and hamlet in southern Spain, in the municipality of La Carolina, in the province of Jaén, in the eastern part of the Sierra Morena region, 15 kilometres (9.3 mi) from the border with the province of Ciudad Real.

Imperator totius Hispaniae is a Latin title meaning "Emperor of All Spain". In Spain in the Middle Ages, the title "emperor" (from Latin imperator) was used under a variety of circumstances from the ninth century onwards, but its usage peaked, as a formal and practical title, between 1086 and 1157. It was primarily used by the kings of León and Castile, but it also found currency in the Kingdom of Navarre and was employed by the counts of Castile and at least one duke of Galicia. It signalled at various points the king's equality with the rulers of the Byzantine Empire and Holy Roman Empire, his rule by conquest or military superiority, his rule over several ethnic or religious groups, and his claim to suzerainty over the other kings of the peninsula, both Christian and Muslim. The use of the imperial title received scant recognition outside of Spain and it had become largely forgotten by the thirteenth century.

The analogous feminine title, "empress" (Latin imperatrix), was less frequently used for the consorts of the emperors. Only one reigning queen, Urraca, had occasion to use it, but did so sparingly.
