Battle of Brunanburh

Why is the Battle of Brunanburh important? “This poorly recalled battle is actually one of the most important in British history since Athelstan’s crushing defeat of the combined Norse-Celtic force facing him (King Athelstan) irrevocably confirmed England as an Anglo-Saxon kingdom, forcing the Celtic kingdoms to consolidate in the positions they occupy today.” [Thanks to Wikipedia].

PS: I like the suggestion, having been born in Bebington, that “the Brackenwood golf course was cited in 2004 as a likely site for the Battle of Brunanburh in AD 937”.
