The Primary Chronicle is a historical text that chronicles the early history of the East Slavs, particularly focusing on the formation of the state of Kievan Rus. Compiled in the early 12th century, it combines historical accounts, legends, and religious narratives, providing insights into the culture and politics of the time. Written in Old East Slavic, the chronicle is attributed to various authors, with the most notable being Nestor, a monk from the Kyiv Monastery of the Caves. It serves as a crucial source for understanding the origins of the Ukrainian, Belarusian, and Russian peoples and their shared heritage.
