Sudebnik of 1497

The Sudebnik of 1497 (Russian: Судебник 1497 года), also known as the Sudebnik of Ivan III (Russian: Судебник Ивана III), was a collection of laws introduced by Ivan III in 1497. It played a big part in the centralisation of the Russian state, the creation of all-Russian legislation, and the elimination of feudal fragmentation. It was later replaced by the Sudebnik of 1550 under Ivan IV.
