The history of Pangi can be inferred from some inscriptions, legends, and traditions. There are a few scattered pieces of evidence that, when gathered, reveal the pages of Pangi's history. Before the rule of the princely states, there must have been a period of local governance, as is evident from the
Caste system. There are also some legends that suggest the Pangwal tribal people migrated here from neighboring areas. It is possible that occasionally, owing to political influence, part of central Asian trade deviated from its original course and followed the less accessible valley of
Cinab,but under ordinary circumstances it must always have returned to its natural channels. Earliest known evidence of human settlements comes from the stone inscriptions at
Luj and
salhi. The
inscription at
Luj was erected by some local
Rana of that time. It contains a verified description of the year when King
Jasht Varman of Chamba ascended the throne. The inscription clearly states that this stone was erected during the first year of King Jasht Varman's reign. The establishment year is noted as
samvat 8, which corresponds to the year 1105 AD. From this year onward, the chronology of the Chamba kings became accurate. The inscription suggests that At that time, the kingdom of Chamba extended up to the village of Luj in Pangi. The inscription at
salhi reveals that the stone was established in the 27th year of King Lalit Varman's reign by a
rana named
Rajanaka Ludarpal. The year of establishment is given as Shastra Samvat 46, which was in use in the Chamba kingdom at that time. Upon calculating the timeline, King Lalit Varman's reign is determined to have started in 1143 CE, and his 27th year corresponds to 1170 CE. On that stone, Pangi was referred to as "पंगति", while in the local language, people called it "पैंगइ". These stone inscriptions suggest that local ranas ruled the area under the suzerainty of the kings of Chamba. The descendants of these ranas still live humble peasant lives in the area. Next king to take complete control of Pangi valley was Prithvi Singh.Prithvi singh's father was dethroned by Jagat Singh of Nurpur. Prithvi Singh asked and obtained help in money and troops from the rajas of
Mandi and Suket, to enable him to recover his kingdom. Passing through
kullu, he crossed the
Rohtang Pass into
Lahaul and advanced into Pangi. He visited
Mindhala temple and presented an inscription on a copper plate to the temple. Thereafter he crossed the Chanaini Pass and moved through Churah, and regained his throne at Chamba, expelling the Nurpur officials from the state. Prithvi Singh divided Pangi
ilaqa into three
parganas with their chief places at
Sach,
Killar and
Dharwas.He also ordered the construction of State
Kothis at these places and appointed state representatives at these
Kothis. A little farther down near the village of Phindru before the temple of
Sidh baba the path has been partly hewn out of the solid rock. This was probably done in the reign of Prithvi Singh, as appears from rock-inscription containing the name of him and dated
sastra 18 corresponding to A.D. 1642–3. The temple of
Malasni Devi at
Porthi village also bears an inscription of Prithvi Singh dated
Sastra-Samvat 27 (A.D.1651). Chatar Singh, Prithvi Singh's successor, also visited Pangi to extend his influence over the region. He led his army lower down the Chandrabhaga Valley, invading Paddar. There, he removed the local Ranas and appointed his own officials. He also founded a town on the plain, naming it Chatargarh. This town was later renamed Gulabgarh when the Dogra forces invaded it in 1836. Other royal inscriptions in Pangi include two fountain stones at
Porthi which were constructed in the reign of
Ugar Singh in
Sastra Samvat 1 (A.D.1725). The state
Kothi at
Sach also has an inscription in Takri recording the foundation of building by
Raja Ugar singh in
Samvat 1 (A.D.1725). After the defeat of
Sikhs in Punjab the area opened up to the
British. In 1864, major Blair Reid who was British superintendent to chamba state convinced the Raja to transfer the management of forests of chamba state including the forests of Pangi to the British Government. This was formalized through a lease agreement dated 10 September 1864 for a duration of 99 years, with provisions for revision every 20 years. Under the terms of the lease, the British Government agreed to pay the state an annual amount of Rs. 22,000. As a result, the
forests of the valley were placed under the direct control of the
Imperial Forest Department.The British extensively felled trees from the forests in the region, employing large-scale
logging practices. The
timber was floated downriver to the plains, where it was extracted and utilized for various purposes, including the construction of railway infrastructure and other projects. There was a famine in the valley in 1878–79 due to the early arrival of winter and the destruction of crops. Grain had to be imported from
curah. Potatoes were introduced to the valley in 1878 by R.T. Burney, then superintendent of Chamba State. Owing to its geographical isolation, seasonal inaccessibility, economic underdevelopment, and distinct cultural characteristics, the Pangwalas were recognized as a
Scheduled Tribe in 1966, and Pangi tehsil was subsequently notified as a
Scheduled Area under the Scheduled Areas (Himachal Pradesh) Order, 1975. Pangi Valley experienced a catastrophic
avalanche disaster during the first and second weeks of March 1979. Unseasonal snowfall of 4.5–6 meters was received, burying villages and destroying crops. A total of 232 people were killed, and 523 were reported missing in Lahaul and Pangi areas. ==Geography==
