Administrative division of Lithuania

This article is about the administrative divisions of Lithuania.

In the earliest stages of the formation of the Lithuanian state, there had been several lands (Lithuanian: plural – žemės, singular – žemė), such as Nalšia, Deltuva and Lietuva, as well as others. They were ruled by regional dukes. When King Mindaugas (1251–1263) unified the state, he killed, expelled, or subjugated most of the regional dukes. The lands were either added to ruler's domain or granted to members of his family.

As the Grand Duchy of Lithuania expended into Slavic lands, the title to the acquired principalities was given to the Grand Duke's offspring or his other relatives. For example, Mindaugas granted Black Ruthenia with center in Navahrudak to his son Vaišvilkas; Gediminas sent his brother Fiodor to Kiev. This system had major disadvantages, for the principalities remained semi-independent with loose ties to the central government. Rulers of these principalities were powerful rivals to the Grand Duke, a situation that led to frequent power struggles.

In early 15th century Vytautas the Great initiated administrative reforms. He replaced regional dukes and princes with trustworthy nobles who depended on the favor of the Grand Duke. This marked the rise of Lithuanian nobility. In 1413 Union of Horodło was signed; Vilnius and Trakai Voivodeships were created in ethnic Lithuanian lands, copying the Polish system. The Eldership of Samogitia had a special semi-autonomous status. Former Slavic principalities and duchies largely preserved their old political, social, administrative features. They were only slowly incorporated into administration of the Grand Duchy. The Kiev Voivodeship was established in 1471, other five voivodeships were established between 1504 and 1514. The Smolensk Voivodeship, the largest of all, was established in 1508, but was lost to the Grand Duchy of Moscow in 1514.
