Changes

Season 2, which focused more heavily on Uhtred's trials as he became a slave, got married to Guthrud's sister, and his assistance in taking London and rescuing the Lady Æthelflæd. As this was a period of relatively less conflict, in comparison to Season 1, the series did take more liberties in interpreting historical events. For instance, while Guthrud may have come from a famous Viking father and may have been a slave, relatively little is known about how he ruled.  In the series, he is shown as a weak and easily pliable king, acting to his own detriment and that of Uhtred's. Alfred marrying his daughter Æthelflæd is shown as an important move to unite Mercia and Wessex. This is historically accurate and it likely did cause tension between the two kingdoms as the former powerful kingdom of Mercia became more closely associated with Wessex. The taking of Lady Æthelflæd is, however, a likely fictional event. In effect, there are not a large number of historical events, but the places, such as Cookham, key events (e.g., taking of London), and some of the key characters (e.g., Guthrud and Osferth) are historical. Because relatively little is known about this period, such as how London was taken, the writers were able to add their own version of events to make it an interesting story.
