The Oath of Allegiance — Punakha Dzong, 17 December 1907.

The political vacuum that made the founding possible

By 1906 both principal seats of the old Choesi institutional structure — the Zhabdrung's seat as religious head of state, and the Druk Desi's seat as political head — sat vacant. Druk Desi Sangay Dorji had died in 1903 after an eighteen-year reign; his successor Choglye Truelku Yeshe Nguedrup served briefly before retiring in 1906 (later returning as Je Khenpo, 1915-1917) and no new Druk Desi was nominated. Zhabdrung Jigme Choegyal had died in 1904 and the new Zhabdrung incarnation had not yet been recognised. With both seats empty, the Lhengye Tshog (the Royal Cabinet) faced the institutional question that had hung over the country for the previous century: could the Choesi dual-system framework continue? After deliberation across 1906 and into 1907, the assembled body resolved that the country needed a hereditary monarchy under His Majesty Ugyen Wangchuck — the Trongsa Penlop whose paramount authority across the country had been consolidated since the 1885 settlement at Changlimithang, and whose diplomatic standing had been established at the 1904 Anglo-Tibetan mediation at Lhasa.

The text and the date

The Oath document itself states the date in the canonical Bhutanese form: '17 December 1907, corresponding to the 12th day of the 11th month of our own year of the Earth Monkey'. The text affirms the unanimous election of His Majesty Ugyen Wangchuck as the First Druk Gyalpo, the principle of hereditary succession through His male line, the continued role of the Je Khenpo and the Zhung Dratshang in the religious life of the country, and the institutional framework for the new constitutional structure. The choice of date is significant — the Earth Monkey year of the Bhutanese lunar calendar carries auspicious religious associations; the date 17 December has remained the Bhutanese National Day for over a century. The two original copies of the Oath are preserved in the National Archives.

Common questions

Why was Punakha Dzong chosen as the venue?

Punakha Dzong was the winter capital of the Bhutanese state from the founding of the dual-system institutional structure by Zhabdrung Ngawang Namgyal in 1637 until the gradual shift of administrative functions to Thimphu in the 1950s and 1960s. The dzong has the principal religious-political weight of any building in the country. Choosing Punakha for the 1907 founding established continuity with the four-hundred-year institutional tradition and gave the new constitutional structure the maximum religious-political legitimacy.

What is the Nga Chudrugma seal?

The Nga Chudrugma is the personal seal of Zhabdrung Ngawang Namgyal, the founder of the unified Bhutanese state in the 17th century. The seal has served as the official seal of every Zhabdrung successor across the subsequent centuries and is the principal symbol of the religious-political authority of the Bhutanese state. Imprinting it in red on the 1907 Oath was the religious-political act that established continuity between the Zhabdrung-era institutional framework and the new hereditary monarchy — the new framework was not a rupture but a constitutional evolution.

Can a visitor see the Oath document?

The two original copies of the Oath are preserved in the National Archives and are not on public display. The Royal Heritage Museum at the Trongsa Ta Dzong has substantial materials on the 1907 founding including reproductions of the seal and the document, photographs from the period, and detailed contextual narrative; for visitors with a serious interest, this is the principal place to encounter the founding. Punakha Dzong itself — open to visitors most days — is the physical site of the signing; the Kuenra (the principal ceremonial hall) is where the 1907 assembly convened.
