The last king of the isolated Himalayan region of Upper Mustang died on Friday in Kathmandu, eight years after he lost his royal title when the centuries-old Buddhist monarchy was abolished. He had not been well on and off since about a year. But was having more difficulty recently because of the cold The former king’s nephew Jigme Dorje Palbar Bista, who was 86, reigned over the arid kingdom high on the Tibetan plateau for more than half a century before stepping down in 2008 when Nepal abolished its own monarchy. “He passed away at 1am at the hospital this morning. He was admitted three days ago. He had not been well on and off since about a year. But was having more difficulty recently because of the cold,” the former king’s nephew Tsewang Bista told AFP. “We will have rituals until Sunday and the final rites will be performed on Monday in Kathmandu,” he said. Nepal annexed the former kingdom of Lo in the 18th century, but allowed the king to retain his title. Bista succeeded his father Angun Tenzing Tandul in 1964, continuing a family line that could trace its lineage back to Ame Pal, the warrior who founded the kingdom in 1380. He supported a CIA-funded guerrilla campaign to oust Chinese forces from Tibet after a failed uprising in 1959, allowing Upper Mustang to be used as a base. Royalty roughing it: Britain’s Prince Harry spends night in Nepali village house Bista had lived most of his life in the medieval walled capital of Lo Manthang, but moved to Kathmandu over a year ago after he became ill, suffering from heart and kidney problems. He acted as a spiritual leader to the local Loba community, who speak a variant of Tibetan and are culturally and linguistically closer to Tibet than Nepal. Ringed by vast canyons and imposing red mountains, the remote kingdom has only recently begun to see glimmers of modernity after a new road connecting Upper Mustang to China and India was completed in 2014. The region was closed to visitors until 1992 and numbers are still strictly regulated.
