The Lusatian Neisse[1][2][3] (Czech: Lužická Nisa; German: Lausitzer Neiße; Polish: Nysa Łużycka; Upper Sorbian: Łužiska Nysa; Lower Sorbian: Łužyska Nysa), or Western Neisse, is a 252-kilometre (157 mi) long river in Central Europe.[4][5] It rises in the Jizera Mountains near Nová Ves nad Nisou, Czech Republic, reaching the tripoint with Poland and Germany at Zittau after 54 kilometres (34 mi), and later forming the Polish–German border for a length of 198 kilometres (123 mi). The Lusatian Neisse is a left-bank tributary of the river Oder, into which it flows between Neißemünde-Ratzdorf and Kosarzyn north of the towns of Guben and Gubin.
According to the 1945 Potsdam Agreement in the aftermath of World War II, the river became part of the Polish western border with Germany (the Oder-Neisse line). Being the longest and most notable of the three rivers named Neisse (Neiße) (German) or Nysa (Polish) (the two other rivers being the Eastern Neisse (Polish: Nysa Kłodzka; German: Glatzer Neisse) and Raging Neisse (Polish: Nysa Szalona; German: Wütende Neiße or Jauersche Neiße)), it is simply referred to as the Neisse.
From Britanica:
Neisse River, Polish Nysa, either of two rivers now in southwestern Poland (until 1945, in Germany). The better-known Nysa Łużycka, or Lusatian Neisse, is the longer (157 miles [252 km]) and more westerly; it forms part of the German-Polish frontier (see Oder–Neisse Line). The Nysa Kłodzka (Glatzer Neisse), or Neisse of the city of Kłodzko (Glatz), is the shorter (113 miles [182 km]) and lies entirely within Poland. Both rise in the Sudeten mountains, flow northward, and empty into the Oder River.
