The Historia de omnibus Gothorum Sueonumque regibus (History of all the kings of the Geats and the Swedes) is a posthumously published, partly pseudo-historical work by Johannes Magnus, Sweden's last Catholic archbishop. In 1554 (ten years after his death), it was published in Latin by his brother Olaus Magnus.[1]
The Historia was implicitly critical of King Gustav Vasa, who had introduced the Protestant Reformation in 1527 and caused the exile of Johannes Magnus. It was nevertheless used widely by Gustav Vasa's sons and successors, to whom it had been dedicated, since it extolled the glorious past of the Swedish kingdom. In particular, the sons used the (fictitious) king-list which began with Magog, grandson of Noah. As a consequence, Eric XIV and Charles IX adopted much higher regnal numbers than warranted by the historical sources. A Swedish translation was published by Ericus Benedicti Schroderus in 1620. A modern Swedish version, translated by Kurt Johannesson and with comments by Johannesson and Hans Helander, was published in 2018 by Michaelisgillet and the Royal Swedish Academy of Letters, History and Antiquities.
