The unification of Russian lands around Moscow and putting an end to the feudal strife was the key to finally vanquishing the Mongol yoke in 1480. The desire of Russian princes to boost Russian economy in a centralized state is reflected in the new codes of law. Both the Novgorod Judicial Charter and the Moscovite Sudebnik of 1497 provide the foundation for land ownership and the legal guide to protect it in the court of law. This is a big leap forward compared to The Iaroslav’s Statute and Pravda Russkaia which mostly concentrated on judging most common crimes, as well as violations of moral and family values. The new documents describe in detail the structure of the court procedures to determine a person’s right to land. The figure of the judge appears, but still remains a passive force during court. The parties fighting for land have to assume the active role, produce written documents and witnesses , while the judges act as supervisors hoping that the decision would become obvious in the course of the trial. A flaw from the standpoint of contemporary litigation, this was still a great step forward in developing the legal structure of Russian society. An accent on the role of written documents presented as evidence and certifying the right to land is also an important new development. Reducing the freedom of peasants by binding them to land is a controversial measure that reduced their freedom, but at that point of time it seems to have positively contributed to developing the economy of the Russian state in post- Mongol time.
