It was created on January 1, 1999, out of the former Gorzów Wielkopolski and Zielona Góra Voivodeships, pursuant to the Polish local government reforms adopted in 1998. The province's name recalls the historic Lubusz Land (Lebus or Lubus), although part of the voivodeship in fact belongs to the historic region of Silesia.
The functions of regional capital are shared between two cities: Gorzów Wielkopolski and Zielona Góra. Gorzów serves as the seat of the centrally appointed voivode or governor, while Zielona Góra is the seat of the elected regional assembly (sejmik) and the executive elected by that assembly, headed by the marszałek.
The region is mainly flat, with many lakes and woodlands. In the south, around Zielona Góra, grapes are cultivated.
