Title: Sweden–United Kingdom relations
Content:  The earliest wave of migration from present-day Sweden, came from the Viking invasion of Britain in the year 793 when vikings pagans from Scandinavia present-day Denmark, Norway, and Sweden started raiding and settling around the British isles. Viking raids occurred up and down the largely undefended east coast of England and Scotland during the eighth and ninth centuries and Scandinavian settlements became established over the entire island of Great Britain, the most important of which was Jórvík (now York). Viking rule came to an end in the 11th century when Normans invaded the shores of Britain. Despite this, Scandinavian influence is evident in the UK even to this day and many millions of Britons have some Viking heritage (especially in Northern England, Eastern England, Scotland and the Shetland Islands). Another early recording of Swedes in England can be found on the so called England runestones which describes Swedish vikings taking gold, Danegeld, tributes in England. Almost all Runestones of this period mentioning England are found in modern day Sweden.
Title: History of England
Content:   The first recorded landing of Vikings took place in 787 in Dorsetshire, on the south-west coast. The first major attack in Britain was in 793 at Lindisfarne monastery as given by the Anglo-Saxon Chronicle. However, by then the Vikings were almost certainly well-established in Orkney and Shetland, and many other non-recorded raids probably occurred before this. Records do show the first Viking attack on Iona taking place in 794. The arrival of the Vikings (in particular the Danish Great Heathen Army) upset the political and social geography of Britain and Ireland. In 867 Northumbria fell to the Danes; East Anglia fell in 869. Though Wessex managed 
Title: Viking Age
Content:  While few records are known, the Vikings are thought to have led their first raids in Scotland on the holy island of Iona in 794, the year following the raid on the other holy island of Lindisfarne, Northumbria. In 839, a large Norse fleet invaded via the River Tay and River Earn, both of which were highly navigable, and reached into the heart of the Pictish kingdom of Fortriu. They defeated Eogán mac Óengusa, king of the Picts, his brother Bran, and the king of the Scots of Dál Riata, Áed mac Boanta, along with many members of the Pictish aristocracy in battle. The sophisticated kingdom that had been built fell apart, as did

Title: Viking art
Content:  The Vikings' regional origins lay in Scandinavia, the northernmost peninsula of continental Europe, while the term 'Viking' likely derived from their own term for coastal raiding—the activity by which many neighbouring cultures became acquainted with the inhabitants of the region. Viking raiders attacked wealthy targets on the north-western coasts of Europe from the late 8th until the mid-11th century CE. Pre-Christian traders and sea raiders, the Vikings first enter recorded history with their attack on the Christian monastic community on Lindisfarne Island in 793. The Vikings initially employed their longships to invade and attack European coasts, harbours and river settlements on a seasonal basis. Subsequently, Viking activities diversified to include trading voyages to the east, west and south of their Scandinavian homelands, with repeated and regular voyages following river systems east into Russia and the Black and Caspian Sea regions, and west to the coastlines of the British Isles, Iceland and Greenland. Evidence exists for Vikings reaching Newfoundland well before the later voyages of Christopher Columbus came to the New World. Trading and merchant activities were accompanied by settlement and colonisation in many of these territories.
Title: Great Heathen Army
Content:  Viking raids began in England in the late 8th century, primarily on monasteries. The Anglo-Saxon Chronicle for AD 787 reports the first confrontation with the Vikings in England. AD 787 – This year king Bertric took to wife Eadburga, king Offa's daughter; and in his days first came three ships of Northmen, out of Hæretha-land [Denmark]. And then the reeve rode to the place, and would have driven them to the king's town, because he knew not who they were: and they there slew him. These were the first ships of Danishmen which sought the land of the English nation. This incident is regarded, by some, as the first raid on England. Æthelweard's version of the Chronicle, known as the Chronicon Æthelweardi, has a slightly different version of events, 
Title: History of Denmark
Content:  With the beginning of the Viking Age in the 9th century, the prehistoric period in Denmark ends. The Danish people were among those known as Vikings, during the 8th–11th centuries. Viking explorers first discovered and settled in Iceland in the 9th century, on their way from the Faroe Islands. From there, Greenland and Vinland (probably Newfoundland) were also settled. Utilizing their great skills in shipbuilding and navigation they raided and conquered parts of France and the British Isles. They also excelled in trading along the coasts and rivers of Europe, running trade routes from Greenland in the north to Constantinople in the south via Russian and Ukrainian rivers, 
Title: Guthrum
Content:  Viking raids began in England in the late 8th century. The first one probably took place in either 787 or 789. The Anglo-Saxon Chronicle for 787 says that: ""This year king Bertric took to wife Eadburga, king Offa's daughter; and in his days first came three ships of Northmen, out of Hæretha-land [Denmark]. And then the reve rode to the place, and would have driven them to the king's town, because he knew not who they were: and they there slew him. These were the first ships of Danishmen which sought the land of the English nation."" Small-scale raiding of the English kingdoms continued on and off until 865, when a much larger army landed in East Anglia with the intention of invading and conquering. This initial army was reinforced in 871 by the Great Summer Army.
Title: History of Anglo-Saxon England
Content:  Between the 8th and 11th centuries, raiders and colonists from Scandinavia, mainly Danish and Norwegian, plundered western Europe, including the British Isles. These raiders came to be known as the Vikings; the name is believed to derive from Scandinavia, where the Vikings originated. The first raids in the British Isles were in the late 8th century, mainly on churches and monasteries (which were seen as centres of wealth). The Anglo-Saxon Chronicle reports that the holy island of Lindisfarne was sacked in 793. The raiding then virtually stopped for around 40 years; but in about 835, it started becoming more regular. 
Title: Viking Age
Content:  in England, on the island of Thanet, Kent. In 854, a raiding party overwintered a second time, at the Isle of Sheppey in the Thames estuary. In 864, they reverted to Thanet for their winter encampment. The following year, the Great Heathen Army, led by brothers Ivar the Boneless (Halfdan and Ubba), and also by another Viking Guthrum, arrived in East Anglia. They proceeded to cross England into Northumbria and captured York, establishing a Viking community in Jorvik, where some settled as farmers and craftsmen. Most of the English kingdoms, being in turmoil, could not stand against the Vikings. In 867, Northumbria became the northern
