 From The History Hit:

Æthelstan ruled first as King of the Anglo-Saxons, before becoming the first King of England after conquering York and therefore unifying the kingdom for the first time.

He also developed relationships with other rulers in Western Europe: no other Anglo-Saxon king played such a major role in European politics as Æthelstan.
