The Kingdom of Bhutan is divided into 20 districts. Bhutan is located between the Tibet Autonomous Region of China and India on the eastern slopes of the Himalayas in South Asia. Dzongkhags are the primary subdivisions of Bhutan. They possess a number of powers and rights under the Constitution of Bhutan, such as regulating commerce, running elections, and creating local governments. The Local Government Act of 2009 established local governments in each of the 20 dzongkhags overseen by the Ministry of Home and Cultural Affairs. Each dzongkhag has its own elected government with non-legislative executive powers, called a dzongkhag tshogdu. The dzongkhag tshogdu is assisted by the dzongkhag administration headed by a dzongdag. Each dzongkhag also has a dzongkhag court presided over by a dzongkhag drangpon, who is appointed by the Chief Justice of Bhutan on the advice of Royal Judicial Service Council. The dzongkhags, and their residents, are represented in the Parliament of Bhutan, a bicameral legislature consisting of the National Council and the National Assembly. Each dzongkhag has one National Council representative. National Assembly representatives are distributed among the dzongkhags in proportion to their registered voter population as recommended by the Delimitation Commission, provided that "no dzongkhag shall have less than two and more than seven National Assembly constituencies." As of the 2017 census, Thimphu is the most populous dzongkhag, with 138,736 residents; Gasa is the least populous, with 3,952 residents. Thimphu is the most densely populated, with, whereas Gasa is the least densely populated, with. The largest dzongkhag by land area is Wangdue Phodrang, encompassing, while the smallest is Tsirang, encompassing.
History
Medieval Bhutan was organized into provinces or regions headquartered in dzongs which served as administrative centres for areas around them. The dzongs of Paro, Dagana and Trongsa were headed by penlops while other dzongs were headed by dzongpons. Penlops and dzongpons gained power as the increasingly dysfunctional dual system of government eventually collapsed amid civil war. The victorious Penlop of TrongsaUgyen Wangchuck gained de jure sovereignty over the entire realm in 1907, marking the establishment of the modern Kingdom of Bhutan and the ascendancy of the House of Wangchuck. At the direction of the fourth Druk Gyalpo, Jigme Singye Wangchuk, the process of decentralisation of local administration started in 1981 with the formation of a dzongkhag yargye tshogchung in each of the newly created dzongkhags. Four dzongdeys were established in 1988 and 1989: Zone I, including four western districts, seated at Chhukha; Zone II, including four west-central districts, seated at Damphu; Zone III, including four east-central districts, seated at Geylegphug; and Zone IV, including five eastern districts, seated at Yonphula; to "provide a more efficient distribution of personnel and administrative and technical skills." Dzongdeys acted as the intermediary administrative divisions between the dzongkhag administration and the central government. Although Thimphu dzongkhag and Thimphu thromde were within the boundaries of Zone I, they stayed outside the zonal system. By 1991, however, only Eastern dzongdey was fully functional. Zone I, Zone II and Zone III were "indefinitely" disabled in early 1991. Zone IV also ceased to function in mid-1992. Dzongdeys slowly lost relevance and went defunct as they were not included in the Constitution of Bhutan and the Local Government Act of 2009, which repealed the previous local governments and administrative divisions. Under the Dzongkhag Yargay Tshogdu Chathrim of 2002, a dzongdag, assisted by a dzongrab, carry out administrative activities, while the DYT coordinates all developmental activities within the dzongkhag. Each DYT includes representatives of the municipalities and the towns within the dzongkhag, who elect a chairperson from among themselves. The DYTs also had non-voting members, which included the dzongdag, the dungpa and the dzongkhag officials from various sectors such as the chief engineer, and the planning, finance, education, agriculture, forestry, animal husbandry, and health officers. The Constitution of 2008 laid basic provisions for an elected dzongkhag tshogdu and dzongkhag courts in each dzongkhag. The Local Government Act of 2009 further codified the election process of dzongkhag tshogdu, the appointment process of dzongkdag, and the role of dzongkhag courts within the judicial system of Bhutan. It also repealed all previous acts and laws regarding local governments, including the Dzongkhag Yargay Tshogdu Chathrim of 2002.
Political structure
Under the LocalGovernment Act of 2009, the dzongkhag tshogdu is the non-legislative executive body of the dzongkhag, composed of the gup and the mangmi from each gewog, and representatives from the thromdes of that dzongkhag. They are empowered to enforce rules on health and public safety, regulate environmental pollution, advertise in regard to environmental aesthetics, regulate broadcast media in accordance with the Information, Communications, and Media Act, regulate gambling, and raise their own funds. They also oversee the dzongdag. A dzongdag, in turn, is responsible for maintaining law and order, and for enforcing the driglam namzha.
