Russkaya Pravda
Of all their princes, Novgorodians most cherished the memory of Yaroslav the Wise, who sat as Prince of Novgorod from 1010 to 1019, while his father, Vladimir the Great, was a prince in Kiev. Yaroslav promulgated the first written code of laws (later incorporated into Russkaya Pravda) among the Eastern Slavs and is said to have granted the city a number of freedoms or privileges, which they often referred to in later centuries as precedents in their relations with other princes. His son, Vladimir, sponsored construction of the great St. Sophia Cathedral, more accurately translated as the Cathedral of Holy Wisdom, which stands to this day.
