Zemsky Sobor
The Sobornoe Ulozhenie () was a legal code promulgated in 1649 by the Zemsky Sobor under Alexis of Russia as a replacement for the Sudebnik of 1550 introduced by Ivan IV of Russia. The code survived well into the 19th century (up to 1849), when its articles were revised under the direction of Mikhail Speransky.
