Context paragraphs:
Ann Naddodsdóttir: Ann Naddodsdóttir (Old Norse: "Ann Naddoðsdōttir" ; mid 9th century, Faroes?  - early 10th century, Bressay, Shetland) was likely a daughter of Naddoddr, the Viking attributed with the discovery of Iceland.

Early Scandinavian Dublin: The First Viking Age in Ireland began in 795, when Vikings began carrying out hit-and-run raids on Gaelic Irish coastal settlements.  Over the following decades the raiding parties became bigger and better organized; inland settlements were targeted as well as coastal ones; and the raiders built naval encampments known as longphorts to allow them to remain in Ireland throughout the winter.  In the mid 9th century, Viking leader Turgeis or "Thorgest" founded a stronghold at Dublin, plundered Leinster and Meath, and raided other parts of Ireland.  He was killed by the High King, Máel Sechnaill mac Máele Ruanaid, which was followed by several Irish victories against the Vikings and the seizure of Dublin in 849.  Shortly after, a new group of Vikings known as the Dubgaill ("dark foreigners") came to Ireland and clashed with the earlier Viking settlers, now called the Finngaill ("fair foreigners").  The wavering fortunes of these three groups and their shifting alliances, together with the shortcomings of contemporary records and the inaccuracy of later accounts, make this period one of the most complicated and least understood in the fledgling city's history.  In 853 a Viking warlord called Amlaíb (, possibly Olaf the White) arrived and made himself king of Dublin.  He ruled along with his brothers Ímar ("Ívarr", possibly Ivar the Boneless) and Auisle ("Ásl").  For the next fifteen years or so, they used Dublin as their base for a series of campaigns against Irish kingdoms.  During these conflicts they briefly allied themselves with several Irish kings.  The Dublin Vikings also carried out a number of raids in Britain at this time.  The deaths of Ivar (c.873) and Olaf (c.874) were followed by internecine conflict among the Vikings.  Although intermittent warfare between the Vikings and the Irish continued, these inner conflicts weakened the Viking colonies and made it easier for the Irish to unite against them.  In 902, Cerball mac Muirecáin, king of Leinster, and Máel Findia mac Flannacáin, king of Brega, launched a two-pronged attack on Dublin and drove the Vikings from the city.  However, in 914 the Vikings now known as the Uí Ímair (House of Ivar) would return to Ireland, marking the beginning of the Second Viking Age.

St Mary's Church, Reculver: St Mary's Church, Reculver, was founded in the 7th century as either a minster or a monastery on the site of a Roman fort at Reculver, which was then at the north-eastern extremity of Kent in south-eastern England.  In 669, the site of the fort was given for this purpose by King Ecgberht of Kent to a priest named Bassa, beginning a connection with Kentish kings that led to King Eadberht II of Kent being buried there in the 760s, and the church becoming very wealthy by the beginning of the 9th century.  From the early 9th century to the 10th the church was treated as essentially a piece of property, with ownership passing between kings of Mercia and Wessex and the archbishops of Canterbury.  Viking attacks may have extinguished the church's religious community in the 9th century, although an early 11th-century record indicates that the church was then in the hands of a dean accompanied by monks. By the time of Domesday Book, completed in 1086, St Mary's was serving as a parish church.

Strickland Brooch: The Strickland Brooch is an Anglo-Saxon silver and niello brooch dated to the mid 9th century, now held by the British Museum.  Although its exact provenance is unknown, it is regarded by scholars as a rare and important artefact from the early mediaeval period in England.

Amlaíb Conung: Amlaíb Conung (Old Norse: "Óláfr" ; died c. 874) was a Viking leader in Ireland and Scotland in the mid-late ninth century.  He was the son of the king of Lochlann, identified in the non-contemporary "Fragmentary Annals of Ireland" as Gofraid, and brother of Auisle and Ímar, the latter of whom founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries.  Another Viking leader, Halfdan Ragnarsson, is considered by some scholars to be another brother.  The Irish Annals title Amlaíb, Ímar and Auisle "kings of the foreigners".  Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power.  The epithet "Conung" is derived from the Old Norse "konungr" and simply means "king".  Some scholars consider Amlaíb to be identical to Olaf the White, a Viking sea-king who features in the "Landnámabók" and other Icelandic sagas.

List of Russian rulers: This is a list of all reigning monarchs in the history of Russia.  It includes titles Prince of Novgorod, Grand Prince of Kiev, Grand Prince of Vladimir, Grand Prince of Moscow, Tsar of All Rus', and Emperor of All Russia.  The list started with a semi-legendary Prince of Novgorod Rurik sometime in the mid 9th century (862) and ended with the Emperor of All Russia Nicholas II who abdicated in 1917, and was executed with his family in 1918.

Auisle: Auisle or Óisle (Old Norse: "Ásl "or" Auðgísl" ; died c. 867) was a Viking leader in Ireland and Scotland in the mid-late ninth century.  He was the son of the king of Lochlann, identified in the non-contemporary "Fragmentary Annals of Ireland" as Gofraid, and brother of Amlaíb Conung and Ímar, the latter of whom founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries.  Another Viking leader, Halfdan Ragnarsson, is sometimes considered a brother.  The Irish Annals title Auisle, Ímar and Amlaíb "kings of the foreigners".  Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power.

Ímar: Ímar (Old Norse: "Ívarr" ; died c. 873) was a Viking leader in Ireland and Scotland in the mid-late ninth century who founded the Uí Ímair dynasty, and whose descendants would go on to dominate the Irish Sea region for several centuries.  He was the son of the king of Lochlann, identified in the non-contemporary "Fragmentary Annals of Ireland" as Gofraid.  The "Fragmentary Annals" name Auisle and Amlaíb Conung as his brothers.  Another Viking leader, Halfdan Ragnarsson, is considered by some scholars to be another brother.  The Irish Annals title Amlaíb, Ímar and Auisle "kings of the foreigners".  Modern scholars use the title "kings of Dublin" after the Viking settlement which formed the base of their power.  Some scholars consider Ímar to be identical to Ivar the Boneless, a Viking commander of the Great Heathen Army named in contemporary English sources who also appears in the Icelandic sagas as a son of the legendary Viking Ragnar Lodbrok.

Uí Ímair: The Uí (h)Ímair ] , or Dynasty of Ivar, was a royal Norse dynasty which ruled much of the Irish Sea region, the Kingdom of Dublin, the western coast of Scotland, including the Hebrides and some part of Northern England, from the mid 9th century.
