Timeline of Lo

• Until the late fourteenth century, Lo was part of Ngari, a name for far western Tibet. Ngari was not a true political entity, but rather a loose collection of feudal domains that also included parts of Dolpo. By the 14th century, much of Ngari, as well as most of what today is western Nepal, was part of the Malla Empire governed from their capital at Sinja, near Jumla.
• 1380 - Shresrab becomes the dzongpon (military commander and provincial commissioner) of Lo for the Gung-thang kings of Tibet. He holds a semi-independent status, which allows him to secure the government for his lineal descendants.
• 1400 - His son, Tshang is recognised as dzongpon of Lo, Nar, Nyishang, Manang, Phug, and Nubri.
• 1425 - His son, the warrior-monk Ama Pal, succeeds as dzongpon.
• 1440-1442 – Ama Pal consolidates his power in the upper Kali Gandaki Valley and extends his influence over a wide region in western Tibet, thus founding the Buddhist Kingdom of Lo. He defeats the Zhang-pa army, declares his independence, and is enthroned as gyalpo, although his kingdom remains closely tied by language and culture to Tibet.
• 1442 - Ama Pal is recognized as an independent ruler by the Gung-thang king of Tibet and assumes the title of chosgyal.
• 1443 – Ama Pal transferrs his capital from Sarang to Manthang (the present day capital), constructing many gompas (temples). He subjugates Guge and Purang in western Tibet and founds the Thub-stan shad-rub dar-gyas-ling Monastery at Sarang, which accommodated over 2,000 resident monks and served as a major center of religious learning and worship.
• 1447 – Tenzing succeeds his father as Lo Gyalpo, an enlightened ruler who patronized literature and religion, reorganized the administration and developed the economic welfare of the kingdom, during a reign that was largely peaceful and prosperous.
• 1482 - Krathis succeeds his father as Lo Gyalpo.
• 1513 - Ragspa succeeds his father as Lo Gyalpo. The growing power of Jumla sees a contraction of his hegemony to little more than the traditional areas of Dolpo, Manang and Lo, eventually losing his independence in 1544.

• 1765-1788 - The vassal rulers of Lo make several unsuccessful, attempts to re-establish their independence.
• 1788 - The Nepalese regent, Prince Bahadur Shah, requests an alliance with Lo to complete his plans for unifying Nepal and, with the help of Wanggyal Dorje, subdues his overlord, the Raja of Jumla.
• 1790 – Wanggyal Dorje is awarded the provinces of Manang and Dolpo. He is recognized as a sovereign ruler with the hereditary title of Raja of Lo. He receives a crown acknowledging his new status from Rana Bahadur, the Maharajadhiraja of Nepal, and is granted a golden plumed crown by the Qianlong Emperor of China.
