On the whole I agree with the first reviewer on the book in its totality. I found that chapters 1-3,6, and 10-12 were the most informative. The last chapter on the Norman legacy could be a book unto itself. This is a fascinating book on several levels. The author displays great dexterity in showing how this multi-ethnic and multi-religious Kingdom grew, and prospered for decades. The abilities of the Normans and the talents of the very different populations appear to have been largely complimentary. The reader occasionally will ask themselves, "did the Renaissance start here?"
Sadly, for the kingdom and perhaps Europe in general? What may have been a tolerant model state could not survive their many external enemies and their own weak leaders after the death of Manfred. I would also recommend Barbara M. Kreutz' "Before The Normans," since it deals with the culture & conditions before the arrival of the Normans. The compare & contrast aspects between the two are good reading for any teacher, student, or history buff.
