The Inflanty Voivodeship , or Livonian Voivodeship , also known as Polish Livonia, was an administrative division and local government in the Polish–Lithuanian Commonwealth, since it was formed in the 1620s out of the Wenden Voivodeship and lasted until the First Partition of Poland in 1772. The Inflanty Voivodeship was one of the few territories of the Polish-Lithuanian Commonwealth to be ruled jointly by Poland and Lithuania.
