Sumpa

The Sumpa (Wylie: sum pa) were a tribe living in northeastern Tibet from ancient times. Chinese historical sources refer to them as "Qiang", a term for people living in what is now southwest China, and their actual ethnic identity is not known. Their territory was absorbed by the Tibetan Empire in the late 7th century, after which point they gradually lost their independent identity. The Sumpa identified as the people known to the Chinese as the Supi (蘇毗) or Sunpo (孫波).
