Through Dharma, India and Nepal

Ralpachen was the second eldest of five brothers. The eldest, Prince Tsangma, took Tibetan Buddhist vows with the Nyingma school. The third, U Dumtsen known as Langdarma, is referred to in the sources as "unfit to reign". The younger two brothers both died young.

Ralpachen is considered a very important king in the history of Tibet and Tibetan Buddhism, as one of the three Dharma Kings (chosgyal) of the Yarlung Dynasty, which include Songtsen Gampo the 33rd king, Trisong Detsen the 38th king, and Ralpachen. All three kings respectively contributed in bringing Mahayana Buddhism to Tibet, in revealing the Vajrayana through Guru Padmasambhava, and in supporting the growth of Buddhism, the building of monasteries, and the flourishing of Buddhism with imperial patronage.

The Tibetan Empire during the reign of Ralpachen grew to its largest extent, and the military battles with the Tang Empire led to the 821–823 Tibet–Tang treaty. Three stelae were inscribed with the terms, and one of each was built in Lhasa at the Jokhang Monastery, in Chang'an, and at the agreed border.

The death of Ralpachen in 838 ended the imperial patronage of Tibetan Buddhism, which had begun about eighty years earlier around 755 with Padmasambhava, Shantirakshita and Trisong Detsen. Afterwards, Langdarma, Ralpachen's brother and successor, proceeded to nearly destroy Buddhism in Tibet, together with the 13 Buddhist monasteries, and their ordained monastics, which were built during the reign of Trisong Detsen.

Political activities

The Tibetan Empire reached its greatest extent under his rule, and included parts of China, India, Nepal, the Kingdom of Khotan, Balti, Bruzha (Gilgit and Hunza), Zhangzhung, Hor-yul, Sog-yul, Yugur, and Kamilog (roughly equivalent to present-day Sichuan), as well as almost all of modern Xinjiang and Gansu.

Ralpachen's power was aided by the able military leadership of Zhang 'Bro sTag. In 810 Emperor Xianzong of Tang wrote asking for the return of three prefectures. In 816 Zhang 'Bro sTag led a raid led to within two days journey from the Uyghur capital at Ordu-Baliq. In 819 he attacked the Chinese town of Yanzhou, in the southern Ordos Desert close to the Great Wall of China, when he was referred to as "First Minister". During the negotiations for a peace treaty in 821 he led a violent attack against the Chinese, which may have contributed to Chinese willingness to make peace.

The reign of Ralpachen was characterized by conflicts with China and the Uyghur Khaganate to the north. Tibetans attacked Uyghur territory in 816 and were in turn attacked in 821. After troops were sent towards the Chinese border, Buddhists in both countries sought mediation and the Sino-Tibetan treaty completed in 821/822, which insured peace for more than two decades. Tibet also made peace with the Uyghurs and also, apparently, with the Kingdom of Nanzhao in 822.

A bilingual account of the treaty with China, including details of the borders between the two countries is inscribed on a stone pillar, erected in 823, which stands outside the Jokhang in Lhasa. There was also a pillar with the treaty inscribed on it erected in China and a third was apparently placed at Gugu Meru at the border (which is said by locals to have been stolen by a party of French Tibetologists).
