The Reconquista or the reconquest of al-Andalus was the successful series of military campaigns that European Christian kingdoms waged against the Muslim kingdoms following the Muslim conquest of the Iberian Peninsula by the Umayyad Caliphate. The beginning of the Reconquista is traditionally dated to the Battle of Covadonga, in which an Asturian army achieved the first Christian victory over the forces of the Umayyad Caliphate since the beginning of the military invasion. Its culmination came in 1492 with the fall of the Nasrid kingdom of Granada to the Catholic Monarchs.
The 12th century is the period from 1101 to 1200 in accordance with the Julian calendar. In the history of European culture, this period is considered part of the High Middle Ages and overlaps with what is often called the "'Golden Age' of the Cistercians". The Golden Age of Islam experienced significant development, particularly in Islamic Spain.
The Battle of Las Navas de Tolosa, known in Islamic history as the Battle of Al-Uqab, 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 led the Almohad army, made up of people from all over the Almohad Caliphate.
Inge Haraldsson was king of Norway from 1136 to 1161. Inge’s reign fell within the start of the period known in Norwegian history as the civil war era, and he was never the sole ruler of the country. He is often known as Inge the Hunchback, because of his physical disability. However, this epithet does not appear in medieval sources.
Sigurd Magnusson, also known as Sigurd the Crusader, was King of Norway from 1103 to 1130. His rule, together with his half-brother Øystein, has been regarded by historians as a golden age for the medieval Kingdom of Norway. He is otherwise famous for leading the Norwegian Crusade (1107–1110), earning him the eponym "the Crusader", and was the first European king to participate in a crusade personally.
Eystein II ; c. 1125 – 21 August 1157) was king of Norway from 1142 to 1157. He ruled as co-ruler with his brothers, Inge Haraldsson and Sigurd Munn. He was killed in the power-struggle against his brother, Inge, in an early stage of the civil war era in Norway.

Gharb al-Andalus, or just al-Gharb, was the name given by the Muslims of Iberia to the region of southern modern-day Portugal and part of West-central modern day Spain during their rule of the territory, from 711 to 1249. This period started with the fall of the Visigothic kingdom after Tariq ibn-Ziyad's invasion of Iberia and the establishment of the Umayyad control in the territory. The present day Algarve derives its name from this Arabic name. The region had a population of about 500,000 people.
In 1114, an expedition to the Balearic Islands, then a Muslim taifa, was launched in the form of a Crusade. Founded on a treaty of 1113 between the Republic of Pisa and Ramon Berenguer III, Count of Barcelona, the expedition had the support of Pope Paschal II and the participation of many lords of Catalonia and Occitania, as well as contingents from northern and central Italy, Sardinia, and Corsica. The Crusaders were perhaps inspired by the Norwegian king Sigurd I's attack on Formentera in 1108 or 1109 during the Norwegian Crusade. The expedition ended in 1115 in the conquest of the Balearics, but only until the next year. The main source for the event is the Pisan Liber maiolichinus, completed by 1125.
The Normans were a population arising in the medieval Duchy of Normandy from the intermingling between Norse Viking settlers and locals of West Francia. The Norse settlements in West Francia followed a series of raids on the French northern coast mainly from Denmark, although some also sailed from Norway and Sweden. These settlements were finally legitimized when Rollo, a Scandinavian Viking leader, agreed to swear fealty to King Charles III of West Francia following the siege of Chartres in 911. The intermingling in Normandy produced an ethnic and cultural "Norman" identity in the first half of the 10th century, an identity which continued to evolve over the centuries. The Normans adopted the culture and language of the French, while they continued the martial tradition of their Viking ancestors as mercenaries and adventurers. In the 11th century, Normans from the duchy conquered England and Southern Italy.
The Norwegian Crusade, led by Norwegian King Sigurd I, was a crusade or a pilgrimage that lasted from 1107 to 1111, in the aftermath of the First Crusade. The Norwegian Crusade marks the first time a European king personally went to the Holy Land.
Morocco–Portugal relations cover a period of several centuries largely historic, and to present not particularly substantial relations. Initial contacts started in the 8th century, when Muslim forces invaded most of the territory of the Iberian peninsula. After the Reconquista, Portugal would then expand into Africa, starting with the territory of Morocco, by invading cities and establishing fortified outposts along the Moroccan coast.
The siege of Alcácer do Sal lasted from 30 July to 18 October 1217. The well fortified city of Alcácer do Sal was a frontier outpost of the Almohad Caliphate facing Portugal. It was besieged by forces from Portugal, León, the military orders and the Fifth Crusade. The latter were led by Count William I of Holland. The expedition was the brainchild of Bishop Soeiro II of Lisbon, whose diocese was threatened by regular raids from Alcácer. King Afonso II of Portugal did not take part in person, but the city was incorporated into his kingdom after its capitulation. The crusaders who took part in the siege, mainly from the Rhineland and the Low Countries, did so without papal authorization and were afterwards ordered to continue on to the Holy Land.
The siege of Tomar was a military engagement that took place in 1190 between the Almohad caliphate who attacked the town of Tomar in Portugal, and the Templar Order, who owned the settlement and successfully defended it from the Muslim attack.
This chronology presents the timeline of the Reconquista, a series of military and political actions taken following the Muslim conquest of the Iberian Peninsula that began in 711. These Crusades began a decade later with dated to the Battle of Covadonga and it ended Its culmination came in 1492 with the Fall of Granada to Isabella I of Castile and Ferdinand II of Aragon. The evolution of the various Iberian kingdoms to the unified kingdoms of Spain and Portugal was key to the conquest of al-Andalus from the Moors.
Portuguese participation in the Reconquista occurred from when the County of Portugal was founded in 868 and continued for 381 years until the last cities still in Muslim control in the Algarve were captured in 1249. Portugal was created during this prolonged process and largely owes its geographic form to it.
The Battle of Formentera (1109) was a part of a military campaign against the muslims of the Balearic Islands. The raid was a huge success for the Norwegian crusaders, facing low casualties. Islamic scholars have referred to the Norwegian raids in the region as part of a larger history of Islamic Spain.
