Statutes of Casimir the Great

Statutes of Casimir the Great or Piotrków-Wiślica Statutes (Polish: Statuty wiślicko-piotrkowskie) - a collection of laws issued by Casimir III the Great, the king of Poland, in the years 1346-1362 during congresses in Piotrków and Wiślica. It was the first and the only significant codification of laws during the times of the Piast dynasty.

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. It would take Polish rulers over two centuries to unite most of the lands that Bolesław controlled under one ruler. This was achieved in the 14th century by Władysław I Łokietek. 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. One of his project included an attempt to unify and codify law in the lands he controlled, in the attempt to build stronger ties between different provinces, and to tie them more tightly to the central government.

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. He was nonetheless able to do so in two major provinces of Poland. The Piotrków statute regulated the law in Greater Poland (Wielkopolska), and the Wiślica statute in Lesser Poland (Małopolska).
