Wallmapu is the word in the Mapuche language to say "Universe" or "set of surrounding lands", currently used by some historians to describe the historical territory inhabited by the Mapuche people of southern South America. The term was coined in the early 1990s by Indigenist groups but gained traction in the 2000s as the Mapuche conflict in Araucanía intensified. Some view the Wallmapu as being composed of two main parts Ngulumapu in the west and Puelmapu in the east, with the southern part of Ngulumapu being known as Futahuillimapu.
