The Rurik dynasty was a ruling family in Eastern Europe that began in the 9th century. It is traditionally believed to have been founded by Rurik, a Varangian prince who established control over the region that would become Russia. The dynasty played a crucial role in the formation of the early Russian state and its expansion. Over the centuries, the Rurik dynasty produced many notable rulers, including Ivan the Terrible and Peter the Great. The dynasty lasted until the early 17th century, when it ended with the death of Feodor I. Its legacy is significant in shaping the history and culture of Russia.
