The book is intended to provide a solid foundation for a comprehensive study of the alliance. The author first goes over the peculiar customs and diplomatics of treating with medieval Russia, then proceeds to detail the diplomatic processes leading to each of the three Danish-Muscovite treaties. Further the surviving Danish and Muscovite treaty texts are published in a new critical edition with commentary and translations into English. And finally, the author reconstructs the missing originals of the treaties for a complete assembly of texts underlying the alliance.
