Tibet, according to the Chinese, was inhabited by many scattered tribes up to the end of the sixth century, when they first heard of the establishment of a kingdom in their midst by Luntsansolungtsan, who, according to the ‘Reearches’ of Ma Tuanlin, during the period K'aihuang, (A.D. 581–600) of the Sui Dynasty, extended his dominion on the south-west as far as P‘olomên (Brâhmaṇa—Central India), till at the beginning of the T'ang Dynasty their army numbered 100,000 warriors, and they become a powerful state. He is probably the Luntsansu of the genealogy on p. 443. It was his son Ch'itsunglungtsan who sent the first mission to the Emperor T'aitsung of the T'ang Dynasty in 634, and was given a Chinese princess in marriage in 641.
