Administrative division of the Kingdom of Poland

Fragmentation of Poland betweens the sons of Bolesław:
  The Seniorate Province, composed of the Eastern Greater Poland, Lesser Poland, Western Kuyavia, Łęczyca Land and Sieradz Land
  Silesian Province of Władysław II
  Masovian Province of Bolesław IV
  Greater Poland Province of Mieszko III
  Sandomir Province of Henryk
  Province of Bolesław's widow, Salomea, composed of Łęczyca Land - to revert to seniorate province upon her death
  Pomeranian vassals of the ruler of the seniorate province

The administrative division of the Kingdom of Poland evolved over the several centuries.

The 11th century Testament of Bolesław III Krzywousty split the early Kingdom of Poland 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 (ex. 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).
