His minority seems a time of even deeper Lhasan political intrigue and power struggles than his predecessor's. By 1862 this led to a coup by Wangchuk Shetra, a minister whom the Regent had banished for conspiring against him. Shetra contrived to return, deposed the Regent, who fled to China, and seized power, appointing himself 'Desi' or Prime Minister. He then ruled with "absolute power" for three years, quelling a major rebellion in northern Kham in 1863 and re-establishing Tibetan control over significant Qing-held territory there. Shetra died in 1864 and the Kashag re-assumed power. The retired 76th Ganden Tripa, Khyenrab Wangchuk, was appointed as 'Regent' but his role was limited to supervising and mentoring Trinley Gyatso.
