Natangians or Notangians (Prussian: Notangi; Lithuanian: Notangai; German: Natanger) 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.
Natangians are first mentioned in a 1238 treaty between the Knights and Zwantepolc De Danceke (Świętopełk II of Pomerania). The Treaty of Christburg of early 1249, which assured personal freedom to newly converted Christians, included Natangians. However, the treaty failed to address the underlying causes of the conflict, and Natangians massacred 54 knights in the Battle of Krücken in November 1249. But the victory was short-lived, the Knights regained their strength in just two years and continued their crusade. In 1255 they built Königsberg (now Kaliningrad) at the mouth of Pregel river, right on the border between Natangia and Sambia.
During the Great Prussian Uprising (1260-1274), the Natangians elected Herkus Monte, who was educated in Germany, as their chief. At first he was successful and defeated the Knights in the Battle of Pokarwis and Battle of Löbau. However, the rebels were unable to capture the brick castles built by the Knights and were defeated. Herkus, who had been one of the most prominent leaders of the Prussians, was captured and hanged in 1273. The Natangian nobles submitted to the Germans, who promised privileges and undisturbed ownership of their estates. Natangians, led by Sabynas and Stanta, rebelled for the last time in 1295.
When German colonists settled in the area, the Natangians kept their local language and customs up until the 17th century. Later on, their identity disappeared by the end of the 17th century or the beginning of the 18th century as they merged with the German population, but the local populace still defined themselves as "Natangians" up to 1945 and even the local newspaper of Landsberg (Górowo Iławeckie) was called "Natanger Zeitung" after 1919.
