The definite strength of this book's historical analysis is the complexity it brings to "realist" historiography [in the sense of focusing on 'great powers' like the Ottomans or Poland].

Slavery was a fact of life…Its basic features – acquisition by raiding or war, public and private sales, the economic and military function, its legal status, the possibility of manumission – were the same on either side of the Christian–Muslim divide. And...that divide was constantly criss-crossed by individuals and agents of many kinds, seeking to organize an exchange or a ransom.
