Czersk Land (Polish: ziemia czerska, named after the town of Czersk) was an administrative unit (ziemia) of the Kingdom of Poland and the Polish–Lithuanian Commonwealth. With its capital in the town of Czersk, it belonged to the Masovian Voivodeship.
The history of Czersk Land as a separate administrative unit dates back to 1245, when Duke Konrad I of Masovia moved the seat of the castellany from Grójec to Czersk, making Czersk the major urban and political center of southern Mazovia. In 1377, Siemowit III, Duke of Masovia called a council in Sochaczew, during which he disbanded castellanies, and following the example of the Kingdom of Poland, created ten lands, all divided into counties. Therefore, the Land of Czersk was established, with three counties: Czersk, Warka and Grójec. It stretched from Mińsk Mazowiecki to Grojec, along both banks of the Vistula, including the town of Garwolin.
The Warsaw metropolitan area (known in Polish as: aglomeracja warszawska or Miejski Obszar Funkcjonalny Warszawy) is the metropolitan area of Warsaw, the capital of Poland. The metropolitan area covers ten counties in the Masovian Voivodeship, with an area of 6,100 km (2,400 sq mi) and a population of around 3.5 million in 2022. The area constitutes a separate NUTS 2 unit, as well as a separate police region with a dedicated Capital Metropolitan Police Headquarters, both of them carved out from the Masovian Voivodeship as an exception, as Polish NUTS 2 areas and police regions are in general identical to the territories of voivodeships.
The largest cities or towns within the metropolitan area are Warsaw, Pruszków, Legionowo, Otwock, Mińsk Mazowiecki, Piaseczno and Wołomin.
