“The First King of England” is a foundational biography of Æthelstan (d. 939), the early medieval king whose territorial conquests and shrewd statesmanship united the peoples, languages, and cultures that would come to be known as the “Kingdom of the English.” In this panoramic work, David Woodman blends masterful storytelling with the latest scholarship to paint a multifaceted portrait of this immensely important but neglected figure, a man celebrated in his day as much for his benevolence, piety, and love of learning as he was for his ambitious reign.
