 The Russkaya Pravda is the legal code of the Kievan Rus' and Rus' principalities. Cultural links to the Byzantine Empire are not reflected in Rus' legislation; in fact, the Kievan Rus' code had a far more humane approach to law making than any other Eastern European civilization, with a total absence of capitol or corporal punishment.
