. The author argues that migration was a key factor in the emergence and spread of diseases such as plague typhoid fever cholera and malaria which had devastating effects on local populations and played a crucial role in shaping the political economic and social history of the region. The book 'Migration and Disease in the Black Sea Region: Ottoman-Russian Relations in the Late Eighteenth and Early Nineteenth Centuries' by [Author name] provides a comprehensive examination of the interconnectedness of human migration, environmental factors, and the spread of diseases in the Black Sea region during the late 18th and early 19th centuries. The author draws upon a wealth of Ottoman, Russian, and Bulgarian archival sources to explore how the interactions between these three empires contributed to the emergence and proliferation of deadly diseases such as plague, typhoid fever, cholera, and malaria, which had profound impacts on local populations and shaped the political, economic, and social history of the region. One of the central arguments of the book is that migration was a critical factor in the spread of diseases across the region. As people moved from one place to another, they carried with them not only their physical presence but also their pathogens, leading to the rapid transmission of diseases across borders. This process was exacerbated by the porous nature of the frontiers between the Ottoman and Russian empires, which allowed for easy movement of people and goods but also facilitated the spread of disease-carrying vectors like insects and rodents. Furthermore, the author argues that the environment played a crucial role in the emergence and spread of diseases, with factors such as climate change, deforestation, and water scarcity creating ideal breeding grounds for disease-causing organisms. The book highlights the need to study and understand the process of technology evolution in order to appreciate the complex interplay between human migration, environmental factors, and the spread of diseases. The author emphasizes the importance of developing a personal paradigm for perceiving the technological process of developing modern knowledge, as this can serve as the basis for the survival of humanity and the unification of people in a warring state.
