Prince of Novgorod
A further confirmation of an active policy in Kievan Rus' were the marriages of Leszek and Konrad with Rurikid princesses. Leszek first married a daughter (name unknown) of Ingvar Yaroslavich, Prince of Lutsk, and then Grzymisława, perhaps a daughter of Yaroslav III Vladimirovich, Prince of Novgorod. Meanwhile, Konrad married Agafia, daughter of Svyatoslav III Igorevich, Prince of Peremyshl.
