The dominance of English in scholarship sometimes leads to a regrettable blindness toward scholarship in other languages. Laudably therefore, Gregory Leighton does not shy away from including German and Polish scholarship. Such language skills are vital here, given the considerable research output in these languages. Leighton is thus able to offer an overall convincing analysis of the Teutonic Order’s ideology from c. 1201 to 1390, when the Order worked militarily to submit to Christianity the hitherto pagan peoples populating an area largely covering the modern states of Estonia, Latvia, Lithuania, Poland, and Belarus.[...]Leighton’s handling of a very large corpus of texts and physical remains is truly impressive. While his analyses in this book focus on establishing the Order as a self-conscious religious protagonist in the Baltic—using the maps to visualize the interconnectedness of the Order’s religious signposts—it might be worth considering an even deeper investigation into what the maps show—or don’t show: did the Order sacralize landscape as a part of conquest and conversion, or did the sacralization of landscape remain an inward “exercise” to strengthen the Order itself after military successes?
