Dariusz Kolodziejczyk Brill Academic Publishers, Incorporated, 2011. This is an extensive study, supplemented by an edition of relevant sources, of the diplomatic contacts between Poland-Lithuania and the Crimean Khanate between the early 15th and the late 18th century. It contains a chronology of mutual relations, a formal analysis of various types of documents, and a glimpse into the working of the Crimean chancery, where Genghisid and Islamic forms mixed with those borrowed from Christian Europe. The book provides a fascinating insight into the intercultural exchange between Catholic Poland (with Latin and then Polish as the main chancery language) and predominantly Orthodox Lithuania (with Ruthenian as the main chancery language) on the one hand, and the Muslim Crimean Khanate (with Khwarezmian Turkic and then Ottoman Turkish as the main chancery language) on the other. It depicts Eastern Europe as a zone of contact, where the relations between Slavs and Tatars were by no means always hostile.
