Throughout Gendun Gyatso's life, the Gelugpa were opposed and suppressed by older rivals, particularly the Karma Kagyu and their Ringpung clan patrons from Tsang, who felt threatened by their loss of influence. In 1498 the Ringpung army captured Lhasa and banned the Gelugpa annual New Year Monlam Prayer Festival started by Tsongkhapa for world peace and prosperity. Gendun Gyatso was promoted to abbot of Drepung in 1517 and that year Ringpung forces were forced to withdraw from Lhasa. Gendun Gyatso then went to the "Gongma" (King) Drakpa Jungne to obtain permission for the festival to be held again. The next New Year, the "Gongma" was so impressed by Gendun Gyatso's performance leading the Festival that he sponsored construction of a large new residence for him at Drepung, 'a monastery within a monastery'. It was called the Ganden Phodrang, a name later adopted by the Tibetan Government, and it served as home for Dalai Lamas until the Fifth moved to the Potala Palace in 1645.
