The present Yearbook is subtitled Historical and Technological Dynamics: Factors, Cycles, and Trends. Its articles demonstrate different forms, patterns, and modes of evolutionary development of societies and their subsystems both over very long periods (in fact, the whole historical process) and over relatively short time intervals. We believe that without an in-depth analysis of the forms and mechanisms of development, it is more difficult to understand both the dynamics of the historical process and many contemporary issues rooted in history. The issue consists of three sections: (I) Long-term Dynamics Factors; (II) Political Cyclicity and Trends; (III) Technological Dynamics and Phases. We hope that this issue will be interesting and useful both for historians and mathematicians, as well as for all those dealing with various social and natural sciences.
