The book 'Ордынский фронтир контактные зоны лесостепного пограничья Южной Руси в XIII – первой половине XV вв. ' by [Author's name] is a comprehensive study of the history of the southern regions of Russia during the 13th to 15th centuries, specifically focusing on the administrative, political, economic, and ethnocultural integration of these lands into the Mongol Empire and the Golden Horde. The author argues that the so-called "contact zones" that emerged during this period were not limited to specific areas but rather spanned across various regions of the southern forest-steppe and forest zone. The book is divided into several chapters, each exploring a different aspect of the historical context of the region during this time period. The first chapter provides an overview of the geographical and environmental factors that shaped the development of the region, including the impact of climate change and the presence of nomadic tribes. The second chapter delves into the political and administrative structures that governed the region, highlighting the complex web of alliances and conflicts between the Mongols, the Golden Horde, and the local populations.
