This vivid and authoritative biography of Henry I was edited and completed by Amanda Clark Frost after Hollister's death in 1997. This biography presents a major reassessment of Henry's character, challenging previous interpretations, and places the history of his reign within the political setting of the day. The king, magnates, royal administration, his relationship with the church, diplomacy, the role of his family, most notably the marriages of his children, are all discussed.
