This book was originally written in 1963 and was reprinted in 2001 with a new prologue addressing advances in understanding. It also has added footnotes here and there, but frankly this isn't enough. It is full of old scholarship, not much of which anyone would really agree with now and I suspect that a lot probably made people spill their tea back in 1963, too. The section on the origins is very badly dated, but Brooke's level of interest in 'Bretwalda' really takes the biscuit. Most authors will acknowledge the list exists and suggest that it may be a partisan list of kings who may have exercised a form of overlordship at certain times. They will run a mile from anything beyond that, but Brooke gives it a lot more emphasis than it deserves.
The first few chapters are arranged thematically, king-making, the occupation of a king and then queens. Here Brooke is oddly selective in the evidence and reigns he wants to discuss. Beowulf, Bede, Alfred, Edward the Confessor, Harold and the Normans get mentions whilst he talks of these themes, but not a lot in-between is brought into play. There is a lot left out. Brooke has his own definite areas of interest and doesn't stray far from them. Things get little better when Brooke gets to the linear history chapters, with the years 670-871 disposed of in a chapter called 'Interlude' which lasts for 4 whole pages. His part on genealogies is interesting. However, this is probably the highlight of it all.
Brooke is oddly reticent in places, too, such as saying that Aethelraed II's mother may have played a part in his accession, when others would have said something a lot more emphatic. In other places he is pretty vague, such as recording a resumption of Viking in attacks in the 890s, when he could just as easily been more specific. It's also very wordy and seldom have I seen someone spend so many words to say so little. This isn't helped by him including whole chunks of Asser. It's nice to see original sources quoted where they buttress an argument, but here we get whole paragraphs of it and little in the way of rationale for it. In contrast, his comments about the reigns of Edmund and Eadred are so short as to be of the length of this sentence.
This is a book that could have been great, but instead it isn't. I resent having spent a couple of days reading it.
