Lusatia (German: Lausitz, Upper Sorbian: Łužica, Lower Sorbian: Łužyca, Polish: Łużyce, Czech: Lužice) is a historical region in Central Europe. It stretches from the Bóbr and Kwisa rivers in the east to the Elbe valley in the west, today located within the German states of Saxony and Brandenburg as well as in the Lower Silesian and Lubusz voivodeships of western Poland. After the conquest of Eastern Germany by the Soviet Army and the partition in 1945 the eastern part of Lusatia along the Lausitzer Neisse river was handed to Poland (see Oder-Neisse Line).
The name derives from the Sorbian word luzicy meaning "swamps" or "water-hole".
