This lecture explores the formation of the Kyivan Rus' state around the year 1000 CE. Timothy Snyder discusses the key factors that contributed to state formation in Eastern Europe, including the spread of Christianity, the competition between Frankish and Byzantine influences, the economic context of the slave trade, and the role of the Vikings. He traces the historical trajectory from early Slavic polities like Moravia and Bulgaria to the eventual establishment of Kyiv as a significant political center, culminating in the conversion of Volodymyr the Great and the integration of Rus' into the broader Byzantine cultural sphere.
