Karma Tseten's dynastic regime became known as the Tsangpa, after the Tsang region. He made friendly overtures to the Phagmodrupa dynasty, the weak line of kings in Nêdong in Ü (East Central Tibet). He also made contacts with the Mongols of the Kokonor region, and secured a promise of assistance from the Chogthu tribe. He furthermore undertook expansion towards western Tibet, where the territories Latö Lho and Latö Chang were placed under his authority. This was probably just a case of loose overlordship, since these areas had to be reconquered by his grandson Karma Phuntsok Namgyal in 1612-13. The Rinpungpa tried to revive their fortunes and performed an abortive raid on Kyishö in Ü in 1575. Possibly connected to this, Karma Tseten clashed with the Rinpungpa in the next year. The Karmapa and Shamarpa hierarchs stepped in to mediate in the conflict, but the next years saw fresh trouble between the two. A new war flared up in 1588-89 between Rong, the heartland of the Rinpungpa, and Karma Tseten. In the following year 1590, the Rinpungpa finally had to capitulate which, according to the influential exorcist Sogdogpa, was just as the stream of earlier and later wars had become like water reaching a boil. The event fulfilled the prophecy the polity of Tsang will become a stable alliance and the region henceforth enjoyed a certain inner stability. However, Central Tibet was repeatedly threatened by incursions of Mongol groups. In 1587 they reached Oyug close to Rinpung, and in 1596 they roamed a wide area including Purang, Mustang, Dolpo in Nepal, Mount Kailash, Latö, and Chang. The partial failure of the Mongol raids was attributed to the powerful exorcism of Sogdogpa.
