Tongsab, he held the appointed post of Umzey (Chant Master). A trusted follower of the Shabdrung, Minjur Tenpa was sent to subdue kings of Bumthang, Lhuntse, Trashigang, Zhemgang, and other lords from Trongsa Dzong. After doing so, the Tongsab divided his control in the east among eight regions (Shachho Khorlo Tsegay), overseen by Dungpas and Kutshabs (civil servants). He went on to build Jakar, Lhuentse, Trashigang, and Zhemgang Dzongs. The 10th Penlop of Trongsa Jigme Namgyel (r. 1853–1870) began consolidating power, paving the way for his son the 12th Penlop of Trongsa Ugyen Wangchuck to prevail in battle against all rival penlops and establish the monarchy in 1907. With the establishment of the monarchy and consolidation of power, the traditional roles of provinces, their rulers, and the dual system of government came to an end.
