What is the relationship between the Russian orthodox church and the princess of Kiev?

The relationship between the Russian Orthodox Church and the Princess of Kiev, specifically Princess Olga, is historically significant. Olga, who ruled in the 10th century, is credited with introducing Christianity to Kievan Rus', laying the groundwork for the eventual Christianization of the region. Her grandson, Vladimir the Great, later adopted Christianity as the state religion, further solidifying the connection between the Russian Orthodox Church and Kievan leadership. Olga is venerated as a saint in the Orthodox Church, symbolizing the deep ties between the church and the early rulers of Kievan Rus'.
