The major prince of Russia you are referring to is Prince Vladimir (also known as Vladimir the Great). He played a crucial role in the Christianization of Kievan Rus' in the late 10th century. Vladimir sent representatives to learn about different religions and ultimately decided to adopt Byzantine Christianity (Orthodox Christianity) as the state religion around 988 AD, which had a profound impact on the culture and development of Russia.
