Namri Songtsen (Tibetan:གནམ་རི་སྲོང་བཙན,Wylie:gnam ri srong btsan,ZYPY:Namri Songzän),^[1] also known as "Namri Löntsen"^{[citation needed]} (Wylie:gnam ri slon mtshan) (died 618) was according to tradition,the 32nd King of Tibet of theYarlung dynasty. (Reign: 570 – 618) During his 48 years of reign, he expanded his kingdom to rule the central part of theTibetan Plateau. He also had a good diplomatic partnership with other tribes and Empires. His actions were decisive in the setting up of theTibetan Empire (7th century), to which he can be named co-founder with his son,Songtsen Gampo. HeSieged inKingdom of Sumpa in early 7th century.

The king of southern Tibet, and donated 20,000 households to Namri Songtsen, who gave him thesovereignty of southern Tibet.

Namri Songtsen was a member of the Yarlung tribe, located to the southeast ofLhasa, in the fertileYarlung Valley^[2] where the Tsangpo (known in India as theBrahmaputra) supported both agriculture and human life. TheTibetan plateau was, at this time, a mosaic of clans of mountain shepherds with simple nomadic organizations^[2] where intertribal fighting andrazzia sorties were part of the local economy.^[3] Each clan had several chiefs. These clans had few material and cultural exchanges due to topography, climate, and distance, so each clan, located in a specified network of valleys, had its own culture with little in common with other clans.^[2] These "proto-Tibetans" were isolated from relations with the outside world, though some mountain groups to the east inSichuan,Qinghai and the'Azha kingdom dwelt in border areas contiguous with, or within, the Chinese empire.^[4] Early Chinese sources appear to mention proto-Tibetan peoples in a few rare cases, if theQiang andRong do indeed refer to them.^[5] This changed dramatically by the beginning of theTang dynasty, when the Tibetan kingdom becoming a powerful player in the military history of Eastern and Central Asia.

Several Tibetan historical accounts say that it was in Namri Songtsen's time that Tibetans obtained their first knowledge of astrology and medicine from China.^[6] Others associate the introduction of these sciences with his son.^[7] In the period, knowledge of these and other sciences came from a variety of countries, not only from China,^[8] but also from Buddhist India, Byzantium,^[9][10] and Central Asia.^[11]

Around 600, Namri Songtsen, one of the several Yarlung tribal chieftains, become the uncontested leader of the several Yarlung clans. Using shepherd-warriors he subdued the neighbouring tribes one after another. Expanding his rule to all of modern Central Tibet, including the Lhasa region^[2] allowed him to rule over many groups, and to begin the establishment of a centralized and strong state, with skilled troops who gained experience in their many battles in the early 7th century. This formed an important base for the later conquests by his son, which unified the whole of the Tibetan plateau.^[2] Furthermore, Namri Songtsen relocated the capitol of his kingdom to the Gyama Valley, where he built theGyama Palace.^[12] According to Beckwith, Namri Songtsen sent the first diplomatic missions to open relations with China, in 608 and 609.^[13]

After conquering Sumpa bySiege of Sumpa, Namri Songtsen took the same steps and granted the nobles territories and slaves to gain their loyalty. Toban became the largest power in theTibetan Plateau, and by integrating central and southern Tibet into one, it achieved the effects of population increase, economic development, and military strength, and finally transformed from a tribal state into an ancient state.

However, Toban was a feudal kingdom that did not develop into a centralized state in the end, and there was a limit to being a formally unified state due to the strong power of the nobles.

Namri Songtsen was assassinated by poisoning^{[citation needed]} in 618 or 629/630, by acoup d'état^{[citation needed]} which eventually failed, being crushed by Namri Songtsen's son, who developed his heritage, completing the submission of theTibetan plateau, and, according to later histories, introduced a unified legal code, a Tibetan writing system, an archive for official records, an army, and relations with the outside world.
