Iman Xin Chemjong Limbu or Iman Singh Chemjong Limbu: was a Limbu historian, writer, linguist, lexicographer, folklorist and philosopher of Nepal. Although some say that his middle name "Xin" was spelled as "Singh" due to mainstream Nepalese or Indian influence, others say "Singh" is correct because in his book "Kiratakalina Vijayapurako Sankshipta Itihasa", Chemjong writes his name in Nepali as Iman Singh Chemjong. Chemjong devoted his entire life to studying and documenting various facets of Kirat Limbu tradition and culture at a time when such activities were frowned upon and even punished by the Nepalese ruling elite as being subversive and "anti-national". Chemjong's research into, and publication of, a Kiranti history and culture challenged perceptions of the Nepalese official doctrine that showcased Nepal as a Hindu cultural monolith devoid of alternative narratives.
