1870, amid the continuing civil wars, the 10th Penlop of Trongsa, Jigme Namgyal ascended to the office of 48th Druk Desi. In 1879, he appointed his 17-year-old son Ugyen Wangchuck as the 23rd Penlop of Paro. Jigme Namgyal reigned through his death 1881, punctuated by periods of retirement during which he retained effective control of the country. The pro-Britain Penlop Ugyen Wangchuck ultimately prevailed against the pro-Tibet and anti-Britain Penlop of Paro after a series of civil wars and rebellions between 1882 and 1885. After his father's death in 1881, Ugyen Wangchuck entered a feud over the post of Penlop of Trongsa. In 1882, at the age of 20, he marched on Bumthang and Trongsa, winning the post of Penlop of Trongsa in addition to Paro. In 1885, Ugyen Wangchuck intervened in a conflict between the Dzongpens of Punakha and Thimphu, sacking both sides and seizing Simtokha Dzong. From this time forward, the office of Desi became purely ceremonial.

As a result, a power vacuum formed within the already dysfunctional dual system of government. Civil administration had fallen to the hands of Penlop Ugyen Wangchuck, and in November 1907 he was unanimously elected hereditary monarch by an assembly of the leading members of the clergy, officials, and aristocratic families. His ascendency to the throne ended the traditional dual system of government in place for nearly 300 years. The title Penlop of Trongsa – or Penlop of Chötse, another name for Trongsa – continued to be held by crown princes. As King of Bhutan, Ugyen Wangchuck secured the Treaty of Punakha (1910), under which Britain guaranteed Bhutan's independence, granted Bhutanese Royal Government a stipend, and took control of Bhutanese foreign relations. After his coronation, Uygen further merited the British Delhi Durbar Gold Medal in 1911; the Knight Commander of the Order of the Star of India (KCSI) in 1911; and the Knight Grand Commander of the Order of the Indian Empire (GCIE) in 1921. King Ugyen Wangchuck died in 1926. The reign of the Second King Jigme Wangchuck (1926–1952) was
