In this lecture, Timothy Snyder discusses the formation of the Kyiv State, exploring the complex historical forces and particularities that led to its emergence. He examines the roles of Christianity (both Western and Byzantine), the Viking expansion, the economic context of the slave trade, and the influence of pre-existing Slavic states in shaping this new political entity around the year 1000. The lecture culminates with the conversion of Volodymyr the Great and the establishment of Kyiv as a significant state within the Byzantine sphere of influence, while also highlighting the inherent weaknesses in its system of succession.
