What is "natangians"

Natangians or Notangians ( Prussian: Notangi, ; ) was one of the eleven clans of Prussian people, who lived in Natangia, an area that is now mostly in the Russian exclave Kaliningrad Oblast ( East Prussia before 1945).

In the 13th century when the Teutonic Knights began their crusade against the Prussians, some 15,000 people might have lived in the area between the rivers identified by the Knights as Pregel (now Pregolya) and Alle (now Łyna). The Natangian lands bordered with Sambia in the north and with Warmia in the south. They likely spoke a West Baltic language, now extinct, similar to Old Prussian language.
