Sturluson's Ynglinga saga was created far too late to serve as a reliable source in regards to the events and kings it describes, being separated from the earliest ones by several centuries. Ynglinga saga appears to have been based on an earlier scaldic poem, Ynglingatal, which is quoted at length by Snorri. Ynglingatal is not a reliable source either, though traditionally believed to have been composed at the end of the 9th or beginning of the 10th century, it might be from as late as the 12th century. Sturluson would have had access to older (now lost) manuscripts when writing the Ynglinga saga, but this does not necessarily corroborate anything that appears in the Ynglinga saga as true. What is genuine history and what is myth and legend is today impossible to determine, and everything contained in the saga must as such be regarded as legendary, if not fictional.[4] Modern scholarship does not see sagas such as the Ynglinga saga as good sources for genuine historical information.[11] As a historical source, the Ynglinga saga is much better used as a source on historiography and society during Sturluson's own time than as a source on Sweden's early history.[4]

It is possible that the Yngling line of kings is entirely fictional, invented by later Norwegian rulers to assert their right to rule Norway. In the Viking Age and later, Danish rulers repeatedly attempted to conquer Norway and through inventing a lineage that stretched back centuries, the Norwegian rulers may have attempted to demonstrate their inherent right to their lands and to put themselves on the same level as the Danes, who had historical accounts of their ancestors. The Swedish Ynglings might have been invented to glorify the Norwegian kings further, giving them a glorious and mythical past associated with Uppsala.[12] Most of the sagas known today, the Ynglinga saga included, were composed during a relatively brief period, from the 12th to 13th century, a time when royal power was being consolidated in Norway, Denmark and Sweden. Their creation might thus stem from political and social needs (i. e. justifying the rule of a dynasty), rather than a desire to tell genuine history.[5]

In addition to having been written centuries after the events they describe, the sagas have numerous other problems which make them unsuitable to use as sources. Many of the elements of the Ynglinga saga appear to be based on later, documented, events and people in Scandinavia. For instance, the figure of Aun, described as being driven from Uppsala and taking up court in Västergötland instead, is similar to the historical Swedish king Inge the Elder (r. c.  1079–1084, 1087–1105), who was driven from Uppsala into Västergötland in the 11th century.[13] The Ynglinga saga might also be an example of anti-royal social commentary rather than an attempt to tell history. Many of the kings in the saga are overshadowed by their contemporary vassals and wives,[14] and they are rarely shown in a positive light. The inglorious deaths of many of the Swedish Ynglings; with examples such as murder, burning to death, drowning in mead and being "hag-ridden" to death,[15] might be an attempt by Sturluson to say that the kings who ruled Norway in his time and claimed Yngling descent were not to be taken seriously.[16] Though descent from figures such as Odin and Njord, gods in Norse mythology, might seem a prestigious origin, it would be problematic in early medieval Norway since the kings were Christian and their ancestors were worshipped as Pagan gods. Their addition to the saga might thus have been another attempt by Sturluson to undermine royal ideology.[17]

If some of the Ynglings were real historical figures, they would have ruled during the Migration Period (c.  375–550) and the subsequent Vendel Period (c.  550–790), predating the Viking Age.[8] Historical evidence of early geopolitics in Scandinavia suggests that larger political structures, kingdoms such as medieval Sweden, Norway and Denmark, did not form until the late Viking Age. The centralization of power under one monarch is believed to have resulted from, or at the very least have been connected to, Viking expansion, with petty kings increasing their power through aggressive military ventures directed both to foreign lands (i. e. Viking raids) and against their neighbors.[6]

The sequence of kings presented below is given by the Hervarar saga, a saga written in the 12th or 13th century.[18]

• Ivar Vidfamne (Old Norse: Ívarr inn víðfaðmi; Swedish: Ivar Vidfamne) – founder of the dynasty, deposed the Yngling dynasty.[18]
• Harald Wartooth (Old Norse: Haraldr hilditǫnn; Swedish: Harald Hildetand) – son of Randver, Ivar's vassal king in Denmark, and Alfhild, the daughter of Ivar. Took control over most of Ivar's former empire.[18]
• Eysteinn Beli (Old Norse: Eysteinn hinn illráði; Swedish: Östen Illråde, Östen Beli) – son of Harald Wartooth, inherited Sweden. He ruled until Sweden was conquered by the Danish or Swedish Viking Ragnar Lodbrok (who in some other sagas is said to be the son of a previous Swedish or Danish king, Sigurd Ring).[18]

Map of Ivar Vidfamne's 7th-century empire according to the sagas. Since he is only mentioned in the Icelandic sagas, an empire of this extent is highly unlikely to have existed.

The existence of Ivar Vidfamne and his dynasty, at least in the way described in the sagas, is considered highly unlikely in modern scholarship. As with the Yngling kings, precise dates are not presented in the sagas for Ivar Vidfamne or his descendants, but his reign is estimated to have taken place in the 7th century. The only sources that mention Ivar are Icelandic sagas from centuries after his death. As Ivar is described as building a vast empire, including parts of Britain and northern Germany, it is unlikely that contemporary and later writers in Europe would not have written of him, had he existed. It is possible that the saga preserves a grain of the truth, perhaps being an embellishment of vague memories of an ancient warrior king, but most of what is said of Ivar Vidfamne has to be considered legendary and fictional.[19]

Langfeðgatal presents the following line of kings:

• Ragnar Lodbrok (Old Norse: Ragnarr Loðbrók; Swedish: Ragnar Lodbrok) – earliest king mentioned in Langfeðgatal.[21] Conquered Sweden from Eysteinn Beli according to the Hervarar saga.[18]
• Björn Ironside (Old Norse: Bjǫrn Járnsíða; Swedish: Björn Järnsida) – son and successor of Ragnar Lodbrok.[21]
• Eric Björnsson (Old Norse: Eiríkr; Swedish: Erik) – son and successor of Björn Ironside.[21]
• Eric Refilsson (Old Norse: Eiríkr; Swedish: Erik) – son of Refil, a son of Björn Ironside, and successor of Eric Björnsson.[21]
• Anund Uppsale (Old Norse: Anundr Uppsali; Swedish: Anund Uppsale) and Björn at Haugi (Old Norse: Bjǫrn; Swedish: Björn på Högen) – sons of Eric Björnsson and co-successors of Eric Refilsson.[21]
• Eric Anundsson (Old Norse: Eiríkr; Swedish: Erik) – son and successor of Anund Uppsale.[21]
• Björn Eriksson (Old Norse: Bjǫrn; Swedish: Björn) – son and successor of Eric Anundsson.[21]
• Eric the Victorious (Old Norse: Eiríkr inn sigrsæli; Swedish: Erik Segersäll) and Olof Björnsson (Old Norse: Óláfr; Swedish: Olof) – both sons and co-successors of Björn Eriksson. Eric the Victorious is a real historical king, r. c.  970–995.[21]
• Olof Skötkonung (Old Norse: Óláfr skautkonungr; Swedish: Olof Skötkonung) – real historical king, r. c.  995–1022, son of Eric the Victorious.[21]
• Anund Jacob (Old Norse: Anundr Iacob; Swedish: Anund Jakob) – real historical king, r. c.  1022–1050, son of Olof Skötkonung.[21]
• Emund the Old (Old Norse: Æmunðær gamlæ; Swedish: Emund den gamle) – real historical king, r. c.  1050–1060, illegitimate son of Olof Skötkonung.[21]

A page of the medieval Swedish Västgötalagen. Västgötalagen lists Olof Skötkonung (r. c.  995–1022) as the first King of Sweden

The Langfeðgatal reconstruction of the Munsö dynasty and the later lineage of Swedish kings it presents does not conform with medieval Swedish primary sources. Though a majority of the kings from Olof Skötkonung onwards appear in the Icelandic sources with the same name and overall chronology, the Icelandic sources also contain the figure Blot-Sweyn, who is only present in some of the Swedish sources (and notably absent in Västgötalagen, an important early Swedish legal document) and a king by the name Kol or Erik Årsäll, completely absent in the Swedish sources. The same is true for the Hervarar saga, whose sequence of kings is identical to the sequence presented in Langfeðgatal.[20] In some respects, the royal sequence is more correct in the Langfeðgatal; Swedish medieval sources tend to omit the kings Anund Jacob and Emund the Old, who can be verified through foreign documents and through the coins they minted, and where the Swedish sources present kings as successive, some (such as Inge the Elder) are known to have co-ruled with others, which is accurately presented in the Icelandic versions.[22]

The missionary Ansgar travelled to Sweden several times during the 9th century in an attempt to Christianize the Swedes. In the writings of his companion Rimbert, the Vita Ansgari, several Swedish kings (who all precede Eric the Victorious) and who they met or heard of at Birka, an important Viking Age trading center, are mentioned. Attempts have been made to harmonize Ansgar's kings with the kings mentioned in the sagas but such attempts have to be considered unreliable and unverifiable. The Vita gives no genealogical information in regards to the kings.[7] It mentions the following four kings:

• Björn, who reigned c.  829 when Ansgar first visited Sweden. Björn was reportedly friendly to the missionaries but chose not to convert to Christianity (although one of his chief councilors, Hergeir, did).[7]
• Anund, who is not mentioned as ruling at Birka (possibly ruling somewhere else in Sweden), having been driven from Sweden and taken refuge among the Danes. Anund promised Birka to the Danes as a reward for helping him gain revenge and attacked Birka c.  840. As Birka continues to be ruled by Swedish kings, it is unlikely that the attack succeeded.[7]
• Eric (Erik), who was recently deceased by the time Ansgar visited Sweden for the second time c.  852. According to Rimbert's writings, some of the Anti-Christian Swedes suggested that Eric be worshipped as a god alongside the rest of the Nordic pantheon instead of the new Christian god.[7]
• Olof (Olaf, Olef), who reigned c.  852, during Ansgar's second visit to Sweden, having then only recently come to the throne.[7]

In terms of sources on Viking Age kings, Adam of Bremen, who worked in the 11th century and wrote of Swedish kings, is significantly closer in time and place to the kings he describe than the centuries of separation in the sagas, only being separated from the mentioned rulers by at most about 150–100 years.[7] The Icelandic sources are substantially different from his work, not only in the kings preceding Olof Skötkonung. As the successors of King Stenkil (r. c.  1060–1066), the Icelandic sources give Håkan the Red, followed by a co-regency of Inge the Elder, Halsten and Blot-Sweyn. Adam of Bremen instead gives a more linear succession of Eric and Eric, followed by Halsten, Anund Gårdske and then Håkan the Red. As the direct predecessors of Eric the Victorious, Icelandic sources give Björn Eriksson, preceded by Erik Anundsson. Apart from the kings found in the Vita Asgari, Adam writes that Eric the Victorious was preceded by Anund/Emund Eriksson, who in turn was preceded by Eric Ringsson and Emund/Anund Ringsson, sons and successors of a king by the name of Ring.[23] Adam of Bremen's line of kings is thus:

• Ring, reigning in the early 10th century.[7]
• Eric Ringsson, son of Ring, reigning in the 10th century.[7]
• Emund Ringsson, son of Ring, reigning in the 10th century, possibly together with Eric.[7]
• Emund Eriksson, son of Eric and successor of Emund, reigning possibly c.  975.[7]

The Sparlösa Runestone, created c.  800, mentions several names, including the name Alríkr (Alaric) in an unclear context, the name Eiríkr (Eric) in reference to a king at Uppsala and the name Eyvísl as the son of this Eiríkr. No written source mentions a king by the name Eyvísl, though the context of the stone does not make it clear whether he ruled as king or whether he was simply a prince.[7]
