Łuków County in the past Lukow Land (Polish: ziemia lukowska, Latin: Terra Lucoviensis, Districtus Lucoviensis) or Lukow County was an administrative unit (ziemia) of both the Kingdom of Poland and the Polish–Lithuanian Commonwealth. With seat in the town of Lukow, it was located in extreme northeastern corner of Lesser Poland, and until 1474 belonged to Sandomierz Voivodeship. From 1474 to 1795, Lukow Land was part of Lublin Voivodeship. Its total area was 1928 km2. Lukow Land bordered Lesser Polands’ Lublin County in the south, Lesser Polands’ Stężyca Land in the southwest, Mazovian Czersk Land in the west, Mazovian Liw Land in northwest, Drohiczyn Land (part of Podlasie) in the north and Brzesc Litewski County (part of Grand Duchy of Lithuania) in the east. In early years of Polish statehood, Lukow Land belonged to the Province (Land) of Sandomierz, which later became Sandomierz Voivodeship. In 1474, when Lublin Voivodeship was carved out of Sandomierz Voivodeship, Lukow Land became part of this new administrative unit. Historic town of Lukow was the capital of the land, and the seat of the starosta. Currently, there are only four towns in the territory of this former administrative unit. Apart from Lukow, these are Siedlce, Radzyn Podlaski and Kock. Also, the villages of Serokomla, Tuchowicz and Zbuczyn had town status. After the Partitions of Poland, Lukow Land was annexed by the Habsburg Empire as part of New Galicia (1795). In 1809, it was annexed into the Duchy of Warsaw, and in 1815 – 1916, it was part of Russian-controlled Congress Poland. Due to numerous administrative changes in this corner of historic Lesser Poland lost its ties with the rest of the province, and in the 19th century became called Southern Podlasie. In the Second Polish Republic, former Lukow Land belonged to Lublin Voivodeship. Currently, it is divided between Lublin Voivodeship (Lukow)
