This book has been a long while in the making, and over the years I have acquired many debts both to institutions and to persons. The International Research and Exchange Board of Princeton, New Jersey, was the primary support of the project from its inception. Yale University's A. Whitney Griswold Fund and its Center for International and Area Studies provided support for travel to West European libraries to supplement Soviet holdings. In the Soviet Union the staff of the State Historical Museum (Moscow), the Moscow University Library, the Central Scientific Library of the Academy of Sciences of the Ukrainian SSR (Kiev), the Lenin Library (Moscow), and the Central State Archive of Ancient Documents (Moscow) were particularly helpful. Moscow University was my host for most of my time in Moscow, and I am grateful both for the ties forged there and for V. V, Shuľgin's kind and helpful advice. The kafedra of feudalism of Moscow University's history faculty and the sector of Old Russian literature at the Gorʼkii Institute of World Literature provided a forum for an early discussion of some of my principal conclusions. A. N. Robinson let a novice in the world of seventeenth-century Russian culture know at an early stage that his work had some value where it mattered most.
My debts to others are also very great. Michael McGerr took precious time from his dissertation to teach me how to use a computer. Over the years I have benefitted greatly from the knowledge and opinions of many colleagues, primarily John Boswell, Robert Crummey, D. M. Bulanin, B. L. Fonkich, Robert Harding, Nancy Kollman, Fairy von Lilienfeld, Keith Luria, George Majeska, Edgar H. Melton, Hugh Olmstead, Marc Raeff, and many others. Samuel Ramer suffered (p.vi) through the frustrations and rewards of research for more of this book than he perhaps realizes. My greatest debt, however, is to Leonid Betin, whose immense knowledge and understanding provided unfailing inspiration, support, and warmth over many years.
