Subdivisions of the Kingdom of Poland

Subdivisions of the Kingdom of Poland evolved over several centuries as the fortunes of the several entities known as the Kingdom of Poland ebbed and flowed.
The early Kingdom of Poland was split in the 11th century by the Testament of Bolesław III Krzywousty into several provinces ("prowincja"). The 14th century Wiślica Statutes and Statutes of Casimir the Great also used the term province. Eventually, during the unification of Poland after the fragmentation, the provinces - some of them for a period known as duchies (e.g. the Duchy of Masovia) - became known as lands ("ziemia").
According to the 15th century "Annales seu cronicae incliti Regni Poloniae" ("Annals or chronicles of the famous Kingdom of Poland" of Jan Długosz, the Kingdom of Poland was divided into following lands:
Most of these administrative regions ("ziemia") in turn were transformed into voivodeships ("województwo") around the 14th and 15th centuries (see voivodeships of Poland).
The administrative division became more clear in the Crown of the Polish Kingdom (see also Administrative division of the Polish–Lithuanian Commonwealth).
