The Limbu or Kirati alphabet was probably modelled on the Lepcha alphabet, which is thought to have derived from the Tibetan alphabet. According to many historians, King Sirijonga invented the "Kirat-Sirijonga Script" in the late 9th century. It disappeared for many years and was then reintroduced by Te-ongsi Sirijonga (believed to be reincarnation of King Sirijonga), in the 17th century. In 1925, Iman Singh Chemjong, a Limbu scholar, named the script after Sirijonga who had laid down his life for the preservation and promotion of script in 1743.
