Vikings in the context of Longship

In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, comparable with the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages.

Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in Late antiquity (c. ~3rd–8th centuries) and into the Early Middle Ages (c. 5th–10th centuries). The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empire—came under the rule of the Umayyad Caliphate, an Islamic empire, after conquest by Muhammad's successors. Although there were substantial changes in society and political structures, the break with classical antiquity was incomplete. The still-sizeable Byzantine Empire, Rome's direct continuation, survived in the Eastern Mediterranean and remained a major power. The empire's law code, the Corpus Juris Civilis or "Code of Justinian", was rediscovered in Northern Italy in the 11th century. In the West, most kingdoms incorporated the few extant Roman institutions. Monasteries were founded as campaigns to Christianise the remaining pagans across Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th and early 9th centuries. It covered much of Western Europe but later succumbed to the pressures of internal civil wars combined with external invasions: Vikings from the north, Magyars from the east, and Saracens from the south.

The Kingdom of England was a sovereign state on the island of Great Britain from the 10th century, when it was unified from various Anglo-Saxon kingdoms, until 1 May 1707, when it united with Scotland to form the Kingdom of Great Britain, which would later become the United Kingdom. The Kingdom of England was among the most powerful states in Europe during the medieval and early modern periods.

Beginning in the year 886 Alfred the Great reoccupied London from the Danish Vikings and after this event he declared himself King of the Anglo-Saxons, until his death in 899. During the early tenth century, the various Anglo-Saxon kingdoms were united by Alfred's descendants Edward the Elder (reigned 899–924) and Æthelstan (reigned 924–939) to form the Kingdom of the English. In 927, Æthelstan conquered the last remaining Viking kingdom, York, making him the first Anglo-Saxon ruler of the whole of England. In 1016, the kingdom became part of the North Sea Empire of Cnut the Great, a personal union between England, Denmark and Norway. The Norman Conquest in 1066 led to the transfer of the English capital city and chief royal residence from the Anglo-Saxon one at Winchester to Westminster, and the City of London quickly established itself as England's largest and principal commercial centre.

Greenland is an autonomous territory in the Kingdom of Denmark. It is by far the largest geographically of three constituent parts of the kingdom; the other two are metropolitan Denmark and the Faroe Islands. It shares a small 1.2 km border with Canada on Hans Island. Citizens of Greenland are full citizens of Denmark and of the European Union. Greenland is one of the Overseas Countries and Territories of the European Union and is part of the Council of Europe. It is the world's largest island, and lies between the Arctic and Atlantic oceans, east of the Canadian Arctic Archipelago. Greenland's Kaffeklubben Island, off the northern coast, is the world's northernmost undisputed point of land—Cape Morris Jesup on the mainland was thought to be so until the 1960s. The capital and largest city is Nuuk. Economically, Greenland is heavily reliant on aid from Denmark, amounting to nearly half of the territory's total public revenue.

Though a part of the continent of North America, Greenland has been politically and culturally associated with the European kingdoms of Norway and Denmark for more than a millennium, beginning in 986. Greenland has been inhabited at intervals over at least the last 4,500 years by circumpolar peoples whose forebears migrated there from what is now Canada. Norsemen from Norway settled the uninhabited southern part of Greenland beginning in the 10th century (having previously settled Iceland), and their descendants lived in Greenland for 400 years until disappearing in the late 15th century. The 13th century saw the arrival of Inuit.

The Normans (Norman: Normaunds; French: Normands; Latin: Nortmanni/Normanni) 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 what is now 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, leading to the formation of the County of Rouen. This new fief, through kinship in the decades to come, would expand into what came to be known as the Duchy of Normandy. The Norse settlers, whom the region as well as its inhabitants were named after, adopted the language, religion, social customs and martial doctrine of the West Franks but their offspring nonetheless retained many of their traits, notably their mercenary tendencies and their fervour for adventures. The intermixing between Norse folk and native West Franks 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 Norman dynasty had a major political, cultural and military impact on medieval Europe and the Near East. The Normans were historically famed for their martial spirit, and eventually for their Catholic piety as adherents of the Catholic orthodoxy of the Romance community. The original Norse settlers adopted the Gallo-Romance language of the Frankish land they settled, with their Old Norman dialect becoming known as Norman, Normaund or Norman French, an important literary language which is still spoken today in parts of mainland Normandy (Cotentinais and Cauchois dialects) and the nearby Channel Islands (Jèrriais and Guernésiais). The Duchy of Normandy, which arose from the Treaty of Saint-Clair-sur-Epte, was a great fief of medieval France. The Norman dukes exercised independent control of their holdings in Normandy, while at the same time being vassals owing fealty to the King of France, and under Richard I of Normandy (byname Richard sans Peur, meaning "Richard the Fearless"), the duchy was forged into a cohesive and formidable principality in feudal tenure.

Kyiv, also Kiev, is the capital and most populous city of Ukraine. Located in the north-central part of the country, it straddles both sides of the Dnieper River. As of 1 January 2022, its population was 2,952,301, making Kyiv the seventh-most populous city in Europe. Kyiv is an important industrial, scientific, educational, and cultural center. It is home to many high-tech industries, higher education institutions, and historical landmarks. The city has an extensive system of public transport and infrastructure, including the Kyiv Metro.

The city's name is said to derive from the name of Kyi, one of its four legendary founders. During its history, Kyiv, one of the oldest cities in Eastern Europe, passed through several stages of prominence and obscurity. The city probably existed as a commercial center as early as the 5th century. A Slavic settlement on the great trade route between Scandinavia and Constantinople, Kyiv was a tributary of the Khazars, until its capture by the Varangians (Vikings) in the mid-9th century. Under Varangian rule, the city became a capital of Kievan Rus', the first East Slavic state. Completely destroyed during the Mongol invasions in 1240, the city lost most of its influence for the centuries to come. Coming under Lithuania, then Poland and then Russia, the city would grow from a frontier market into an important centre of Orthodox learning in the sixteenth century, and later of industry, commerce, and administration by the nineteenth.

The territory today known as England became inhabited more than 800,000 years ago, as the discovery of stone tools and footprints at Happisburgh in Norfolk have indicated. The earliest evidence for early modern humans in Northwestern Europe, a jawbone discovered in Devon at Kents Cavern in 1927, was re-dated in 2011 to between 41,000 and 44,000 years old. Continuous human habitation in England dates to around 13,000 years ago (see Creswellian), at the end of the Last Glacial Period. The region has numerous remains from the Mesolithic, Neolithic and Bronze Age, such as Stonehenge and Avebury. In the Iron Age, all of Britain south of the Firth of Forth was inhabited by the Celtic people known as the Britons, including some Belgic tribes (e.g. the Atrebates, the Catuvellauni, the Trinovantes, etc.) in the south east. In AD 43 the Roman conquest of Britain began; the Romans maintained control of their province of Britannia until the early 5th century.

The end of Roman rule in Britain facilitated the Anglo-Saxon settlement of Britain, which historians often regard as the origin of England and of the English people. The Anglo-Saxons, a collection of various Germanic peoples, established several kingdoms that became the primary powers in present-day England and parts of southern Scotland. They introduced the Old English language, which largely displaced the previous Brittonic language. The Anglo-Saxons warred with British successor states in western Britain and the Hen Ogledd (Old North; the Brittonic-speaking parts of northern Britain), as well as with each other. Raids by Vikings became frequent after about AD 800, and the Norsemen settled in large parts of what is now England. During this period, several rulers attempted to unite the various Anglo-Saxon kingdoms, an effort that led to the emergence of the Kingdom of England by the 10th century.

Æthelwulf (Old English: [ˈæðelwuɫf]; Old English for "Noble Wolf"; died 13 January 858) was King of Wessex from 839 to 858. In 825, his father, King Ecgberht, defeated King Beornwulf of Mercia, ending a long Mercian dominance over Anglo-Saxon England south of the Humber. Ecgberht sent Æthelwulf with an army to Kent, where he expelled the Mercian sub-king and was himself appointed sub-king. After 830, Ecgberht maintained good relations with Mercia, and this was continued by Æthelwulf when he became king in 839, the first son to succeed his father as West Saxon king since 641.

The Vikings were not a major threat to Wessex during Æthelwulf's reign. In 843, he was defeated in a battle against the Vikings at Carhampton in Somerset, but he achieved a major victory at the Battle of Aclea in 851. In 853, he joined a successful Mercian expedition to Wales to restore the traditional Mercian hegemony, and in the same year, his daughter Æthelswith married King Burgred of Mercia. In 855, Æthelwulf went on a pilgrimage to Rome. In preparation he gave a "decimation", donating a tenth of his personal property to his subjects; he appointed his eldest surviving son Æthelbald to act as King of Wessex in his absence, and his next son Æthelberht to rule Kent and the south-east. Æthelwulf spent a year in Rome, and on his way back he married Judith, the daughter of the West Frankish king Charles the Bald.

Æthelbald (died 860) was King of Wessex from 855 or 858 to 860. He was the second of five sons of King Æthelwulf. In 850, Æthelbald's elder brother Æthelstan defeated the Vikings in the first recorded sea battle in English history, but he is not recorded afterwards and probably died in the early 850s. The next year Æthelwulf and Æthelbald inflicted another defeat on the Vikings at the Battle of Aclea. In 855, Æthelwulf went on pilgrimage to Rome and appointed Æthelbald King of Wessex, while Æthelberht, the next oldest son, became King of Kent, which had been conquered by Wessex thirty years earlier.

On his way back from Rome, Æthelwulf stayed for several months with Charles the Bald, King of the West Franks, whose twelve-year-old daughter Judith he married. When he returned to England in 856, Æthelbald refused to give up the crown. Most historians believe that Æthelbald continued to be king of Wessex while Æthelberht gave up Kent to his father, but some think that Wessex itself was divided, with Æthelbald ruling the west and his father the east, while Æthelberht kept Kent. When Æthelwulf died in 858, Æthelbald continued as (or became again) king of Wessex and his brother resumed (or carried on) his kingship of Kent.

Æthelred I (alt. Aethelred, Ethelred; Old English: Æthel-ræd, lit. 'noble counsel'; 845/848 to 871) was King of Wessex from 865 until his death in 871. He was the fourth of five sons of King Æthelwulf of Wessex, four of whom in turn became king. Æthelred succeeded his elder brother Æthelberht and was followed by his youngest brother, Alfred the Great. Æthelred had two sons, Æthelhelm and Æthelwold, who were passed over for the kingship on their father's death because they were still infants. Alfred was succeeded by his son, Edward the Elder, and Æthelwold unsuccessfully disputed the throne with him.

Æthelred's accession coincided with the arrival of the Viking Great Heathen Army in England. Over the next five years the Vikings conquered Northumbria and East Anglia, and at the end of 870 they launched a full-scale attack on Wessex. In early January 871, Æthelred was defeated at the Battle of Reading. Four days later, he scored a victory in the Battle of Ashdown, but this was followed by two defeats at Basing and Meretun. He died shortly after Easter. Alfred was forced to pay off the Vikings, but he scored a decisive victory over them seven years later at the Battle of Edington.

The Danelaw (/ˈdeɪnˌlɔː/, Danish: Danelagen; Norwegian: Danelagen; Old English: Dena lagu) was the part of England between the late ninth century and the Norman Conquest under Anglo-Saxon rule in which Danish laws applied. The Danelaw originated in the conquest and occupation of large parts of eastern and northern England by Danish Vikings in the late ninth century. The term applies to the areas in which English kings allowed the Danes to keep their own laws following the early tenth-century Anglo-Saxon conquest of Danish ruled eastern and northern England in return for the Danish settlers' loyalty to the English crown. "Danelaw" is first recorded in the early 11th century as Dena lage.

The Danelaw originated from the invasion of the Great Heathen Army into England in 865, but the term was not used to describe a geographic area until the 11th century. With the increase in population and productivity in Scandinavia, Viking warriors, having sought treasure and glory in the nearby British Isles, "proceeded to plough and support themselves", in the words of the Anglo-Saxon Chronicle for 876.

The Kingdom of León was an independent kingdom situated in the northwest region of the Iberian Peninsula. It was founded in 910 when the Christian princes of Asturias along the northern coast of the peninsula shifted their capital from Oviedo to the city of León. The kings of León fought civil wars, wars against neighbouring kingdoms and campaigns by both the Moors and the Vikings, all in order to protect their kingdom's changing fortunes.

García is the first of the kings described by the charters as reigning in León. It is generally assumed that the old Asturian kingdom was divided among the three sons of Alfonso III of Asturias: García (León), Ordoño (Galicia) and Fruela (Asturias), as all three participated in deposing their father. When García died in 914, León went to Ordoño, who now ruled both León and Galicia as Ordoño II. At Ordoño's death in 924, the throne went to his brother Fruela II (924–925), who died of leprosy a year later. Fruela's death in 925 was followed by a civil war, after which Alfonso, the eldest son of Ordoño II, emerged as the new king Alfonso IV, ruling from 925 to 932. After a further power struggle, Ramiro, the younger brother of Alfonso IV, became king in 932, having captured his brother Alfonso, as well as the three sons of Fruela II – Alfonso, Ordoño and Ramiro. Alfonso IV may have died soon after, but he left two infant sons, called Ordoño and Fruela. When Ramiro died in 951, he left two sons by two different wives. When the elder son Ordoño III, who ruled from 951 to 956, suddenly died aged little more than thirty, he was succeeded by his younger half-brother Sancho I "The Fat" (956–966), as Ordoño had failed to produce a legitimate heir.

The Viking Age (about 793–1066 CE) was the period during the Middle Ages when Norsemen known as Vikings undertook large-scale raiding, colonising, conquest, and trading throughout Europe and reached North America. The Viking Age applies not only to their homeland of Scandinavia but also to any place significantly settled by Scandinavians during the period. Although few of the Scandinavians of the Viking Age were Vikings in the sense of being engaged in piracy, they are often referred to as Vikings as well as Norsemen.

Voyaging by sea from their homelands in Denmark, Norway, and Sweden, the Norse people settled in the British Isles, Ireland, the Faroe Islands, Iceland, Greenland, Normandy, and the Baltic coast and along the Dnieper and Volga trade routes in eastern Europe, where they were also known as Varangians. They also briefly settled in Newfoundland, becoming the first Europeans to reach North America. The Norse-Gaels, Normans, Rus' people, Faroese, and Icelanders emerged from these Norse colonies. The Vikings founded several kingdoms and earldoms in Europe: the Kingdom of the Isles (Suðreyjar), Orkney (Norðreyjar), York (Jórvík) and the Danelaw (Danalǫg), Dublin (Dyflin), Normandy, and Kievan Rus' (Garðaríki). The Norse homelands were also unified into larger kingdoms during the Viking Age, and the short-lived North Sea Empire included large swathes of Scandinavia and Britain. In 1021, the Vikings achieved the feat of reaching North America—the date of which was not determined until a millennium later.

Vinland, Vineland, or Winland (Old Norse: Vínland hit góða, lit. 'Vinland the Good') was an area of coastal North America explored by Vikings. Leif Erikson landed there around 1000 AD, nearly five centuries before the voyages of Christopher Columbus and John Cabot. The name appears in the Vinland Sagas and describes a land beyond Greenland, Helluland, and Markland. Much of the geographical content of the sagas corresponds to present-day knowledge of transatlantic travel and North America.

In 1960, archaeological evidence of the only known Norse site in North America, L'Anse aux Meadows, was found on the northern tip of the island of Newfoundland. Before the discovery of archaeological evidence, Vinland was known only from the sagas and medieval historiography. The 1960 discovery further proved the pre-Columbian Norse exploration of mainland North America. Archaeologists found butternuts at L'Anse aux Meadows, which indicates voyages into the Gulf of Saint Lawrence as far as northeastern New Brunswick. L'Anse aux Meadows has been hypothesized to be the camp Straumfjörð mentioned in the Saga of Erik the Red.

Viking activity in the British Isles occurred during the Early Middle Ages, the 8th to the 11th centuries CE, when Scandinavians travelled to the British Isles to raid, conquer, settle and trade. They are generally referred to as Vikings, but some scholars debate whether the term Viking represented all Scandinavian settlers or just those who used violence.

At the start of the early medieval period, Scandinavian kingdoms had developed trade links reaching as far as southern Europe and the Mediterranean, giving them access to foreign imports, such as silver, gold, bronze, and spices. These trade links also extended westwards into Ireland and Britain.

In the Middle Ages, the Volga trade route connected Northern Europe and Northwestern Russia with the Caspian Sea and the Sasanian Empire, via the Volga River. The Rus used this route to trade with Muslim countries on the southern shores of the Caspian Sea, sometimes penetrating as far as Baghdad. The powerful Volga Bulgars (cousins of today's Balkan Bulgarians) formed a seminomadic confederation and traded through the Volga river with Viking people of Rus' and Scandinavia (Swedes, Danes, Norwegians) and with the southern Byzantine Empire (Eastern Roman Empire) Furthermore, Volga Bulgaria, with its two cities Bulgar and Suvar east of what is today Moscow, traded with Russians and the fur-selling Ugrians. Chess was introduced to Medieval Rus via the Caspian-Volga trade routes from Persia and Arabia.

There was a second route from the Baltic Sea to the Dnieper, which ran along the Western Dvina (Daugava) between Lovat and Dnieper in the Smolensk region and along the Kasplya River to Gnezdovo. The Volga trade route functioned concurrently with the Dnieper trade route, better known as the trade route from the Varangians to the Greeks, and lost its importance in the 11th century.

The Varangians (/vəˈrændʒiənz/ və-RAN-jee-ənz; Old Norse: Væringjar; Medieval Greek: Βάραγγοι, romanized: Várangoi; Old East Slavic: варяже, romanized: varyazhe, or варяги, varyagi) were Viking warriors, traders and settlers, mostly from present-day Sweden, who settled in the territories of present-day Belarus, Russia and Ukraine from the 8th and 9th centuries and established the state of Kievan Rus' as well as the principalities of Polotsk and Turov. They also formed the Byzantine Varangian Guard.

According to the 12th-century Primary Chronicle, a group of Varangians known as the Rus' settled in Novgorod in 862 under the leadership of Rurik. Before Rurik, the Rus' might have ruled an earlier hypothetical polity known as the Rus' Khaganate. Rurik's relative Oleg conquered Kiev in 882 and established the state of Kievan Rus', which was later ruled by Rurik's descendants.
