The Reconquista was one of the most iconic settings of medieval history and is amongst the most, if not the most, known periods concerning the history of the Iberian peninsula, this was the time when Christian Iberians fought against the rule of the Muslim Moors to retake their country from the invaders, a time of constant conflict and small kingdoms, all banded together under the guidance of the Cross.

The real history, as it is often, is not as simple as what the general description might indicate.

For starters, one of the things that must be understood is that despite the name, the Reconquista was not just a Spanish endeavour in the modern sense of the word, the Spain as we know it today never came to properly be until the union between the Catholic Kings and, as we will detail further below, the Reconquista ended sooner for some of the Kingdoms of the Hispanian Peninsula.

The Prelude

We pick up after the fall of the Visigothic realm in the midst of the Late Antiquity, the power of the Goths had been waning in Western Europe in favour of Frankish hegemony amongst the many germanic kingdoms that rose from the ashes of the Western Roman Empire and, with the invasion of the Lombards, the power of their Ostrogothic cousins came to an end. Around this time, King Reccared took the pivotal decision of converting the state religion of the visigoths from Arrian Christianitiy to Catholicism which served to unify the people of the peninsula under one single denomination: Hispani, which would be a decision that would affect the peninsula's destiny in the years to come.

The rise of Islam, and the wars of expansion that came with it, changed the entirety of the reality in the Mediterranean in an unreversable way that would mark the end of the shared history amongst the people of the Mare Nostrum, which shared religion and some degree of cultural affinity until the ascension of the Rashidun, and eventually Umayyad, Caliphate. As it happened, the reason for this was not only the loss of territory from the Christian Basileus to the Arabian newcomers that shocked the world so, but the already showing rifts between the churches in the provinces of Egypt (Miaphysite christians) and Africa (Donatist christians) that would later lead to the religious shift from Christianity to Islam in the north of Africa. Around this time, the squabbles amongst the Visigothic nobles and the kings turned from bad to worse, ending in a civil conflict at the ascension of King Roderic, who is said to have usurped the throne from the sons of the previous king Witiza, which meant that the disunified goths were unable to resist the eventual invasion of their kingdom by the Berber vassals of the Umayyads (hence the term Moor to refer to the muslims), the army of Tariq ibn Ziyad overwhelmed the disunified nobles and took control of most of the peninsula after the disastrous defeat of the visigothic army in the battle of Guadalete, in which many nobles incluiding the usurper king died.

One noble however, known as Pelayo, managed to survive the perilous combat and escaped north; as other of the noble fleed to the neighbouring kingdom of the Franks, he instead went towards the Cantabrian mountains as the kingdom became a province of the Caliphate to form a resistence against the islamic invaders, first refusing to pay the taxes that non-muslims had to pay and later turning to a rebellion with small military action, aided in part due to the difficult terrain that protected the rebel province and the deviation of attention from the muslims to the conquest of the Franks, it was after their memorable defeat in Toulouse that gave rise to Charles Martel that the commander of the Umayyad army decided to take serious action against the iberian rebels to at least save face, this however lead to the famed battle of Covadonga in which the Asutrian rebels, lead by Pelayo himself, managed to defeat and rout the enemy in such a manner that the Umayyad would never again try to challenge the independence of the new Kingdom: The Kingdom of Asturias.

The Beginning

As said before, the Kingdom of Asturias was the first of the new iberian kingdoms from which all of the eventual kingdoms from the medieval period to beyond would have some claim of continuity and it's this kingdom that would start the Reconquista: the many skirmishes that soon followed after the victory at Covadonga managed to inspire the fellow Galician and Asturian nobles to rally to Pelayo, who would spend his realm trying to fortify to his alliances with the local nobility through strategic marriages, his lineage didn't survived him though and after the death of his son Favila without any children of his own the crown passed to the house of Cantabria through the marriage of Pelayo's daugther Ermensinda and Alfonso, son of Pedro, duke of Cantabria and said to be a descendant from the aforementioned Visigothic king Reccared.

This dynasty, known as the Astur-Leonese or Beni Alfons (childs of Alfonso in Arabic), coexisted with the much more known Carolingian dynasty during its inception and would make gains to the south of the Cantabrian mountains and into annex the territory of Galicia and Leon while the Franks conquered the north of Spain, forming the Mark of Spain (Marca Hispanica) from the regions of Navarre and Aragon, the inestability of the

The Five Kingdoms

Around the time that marks the beginning of the High Middle Ages, the various realms that formed the Catholic north began to take shape, this was the starting point upon which the eventually six most representative nations of the Iberian Peninsula would appear: the Castilians, based around the Kingdom of Castille; the Galeo-leonese, members of the Kingdom of Leon; the Catalans, inhabitants of the Kingdom of Aragon; the Basque, living in the Kingdom of Navarra; the Andalusian, ruling the Kingdom of Granada; and, the Portuguese, natives of the Kingdom of Portugal. It must be noted however that because of the unions (yes, unions) between Castille and Leon shortened the term from six to Five Kingdoms, four christian and one muslim.

As said before, one of the misconceptions of the Reconquista is that it was a purely Spanish business while the truth was that all of the listed realms participated in the fight against the muslim dukes in the Iberian soil with some finishing their own fight long before the fall of Granada like Portugal or Aragon
