Professor Zilfi, a well-established, leading historian of the Ottoman Empire, has joined the small but constantly growing group of scholars interested in the study of Ottoman enslavement. Her current book is a most welcome addition to the second wave of studies devoted to the complex history of the practice, which is one of the most diverse and multi-faceted phenomena in the annals of human societies. While Zilfi clearly contributes to the discourse about the topic, she—refreshingly—does not pretend to reinvent the wheel, but rather treats the works of her predecessors with respect, fully engaging with their studies and demonstrating remarkable understanding of the intricacies they sought to explain in an area that had been uncharted territory.
