Feudal Kingdom of England 1042 - 1216 by Frank Barlow
Now into its fourth edition, this highly-regarded text has been fully revised and rewritten. Since the last edition in 1972 much important work has been done on the period, not least by Frank Barlow himself -- with a major study of the English Church between 1066 and 1154, alongside what are now the standard works on William Rufus and Thomas Becket -- and all of this has been fully incorporated into this new edition.
