====Æthelstan of Wessex (r. 927–939)====
{{main|Æthelstan}}
Æthelstan ruled as [[King of the Anglo-Saxons]] from 924 to 927 and [[King of the English]] from 927 to 939. The shift in his title reflects that in 927, Æthelstan conquered the Viking Kingdom of [[York]], previously part of the Northumbrian Kingdom.<ref name="auto">{{harvnb|Foot|2011|p=40}}</ref> His reign was quite prosperous and saw great strides in many fields such as law and economics, but was also characterized by frequent clashes with the [[Scottish people|Scots]] and the Vikings.<ref name="auto"/> Æthelstan died in 939, which led to the Vikings' retaking of York. Æthelstan is widely considered one of the greatest Anglo-Saxon kings for his efforts to consolidate the English kingdom and the prosperity his reign brought.<ref>{{harvnb|Sturluson|1964|pp=42–43}}</ref>
