Statutes of Casimir the Great

In the middle of the 12th century, following the ill-thought testament of Bolesław III Krzywousty, his sons begun the process of fragmentation of Poland.

[2] Władysław's son, Casimir III the Great, earned his singular reputation not through military exploits but through his acumen as a builder, administrator and diplomat.

[3][4] In the end, due to opposition from various factions, which saw the codification and unification of the legal system in the Kingdom of Poland as weakening their position, Casimir was not able to fully accomplish his task.

[6] Further, historians now agree that the Statutes were partially written after the death of Casimir, and later the entire work was incorrectly attributed to him.

[7] They would form the basis of the Polish law in centuries to come, and would be expanded by codification of other customs, precedents and passing of other legal acts.
