Editing Igor of Kiev (section)

==Historiography==
Drastically revising the chronology of the ''Primary Chronicle'', [[Constantin Zuckerman]] argues that Igor actually reigned for three years, between summer 941 and his death in early 945. Zuckerman argues that the 33-year reign attributed to Igor in the ''Chronicle'' is the result of its author's faulty interpretation of Byzantine sources.<ref name="zuckerman">{{cite journal|url=http://www.persee.fr/docAsPDF/rebyz_0766-5598_1995_num_53_1_1906.pdf|title=On the Date of the Khazars' Conversion to Judaism and the Chronology of the Kings of the Rus Oleg and Igor: A Study of the Anonymous Khazar Letter from the Genizah of Cairo|journal=Revue des études byzantines|volume=53|issue=1|date=1995|access-date=5 July 2016|last=Zuckerman|first=Constantin|author-link=Constantin Zuckerman|pages=237–270|issn=0766-5598|doi=10.3406/rebyz.1995.1906}}{{Dead link|date=January 2023 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Indeed, none of Igor's activities recorded in the ''Chronicle'' is dated before 941.

Referring to the [[Ioachim Chronicle]], [[Vasily Tatishchev]] argues that the Swedish princess Efanda, whose existence has been questioned by many historians, was Igor's mother. According to Tatishchev, the name "Ingor" comes from the [[Finnish language|Finnish]] (Izhora) name ''Inger''.<ref>[http://www.magister.msk.ru/library/history/tatisch/tatis004.htm Tatishchev. The History of Russia. Part 1, Chapter 4]</ref> Tatishchev also gives Igor's birth dates from various manuscripts: 875 in the Schismatic manuscript, 861 in the Nizhny Novgorod manuscript, 865 in the Orenburg manuscript.

According to [[Olof von Dalin]], another Igor had land in Sweden and was a frequent guest in Russia. 
He was coregent with [[Eric Anundsson]] and had land in [[Västergötland]] which he had inherited from his father. After his reign, Eric Anundsson became the sole ruler of the Swedish mainland. Igor also aided Eric when Norwegians under [[Harald Fairhair]] raided the Baltic coast. Harald Fairhair lost his son Halfdan the White in a siege of a Swedish fortification in the Baltic. Thanks to Igor Olofsson's help the attack on the Baltic fortifications was thwarted. Igor also took part in a Viking raid on Brittany in 931 described in Frankish chronicles as Incon. This Igor was the son of [[Olof (Swedish king 852)]]. Igor Olofsson led a Swedish expedition helping Igor Ruriksson in his war against the Byzantines. Igor and Igor were related.<ref>https://sv.wikisource.org/wiki/Svea_Rikes_historia/F%C3%B6rsta_delen/Kapitel_18
