A clan from pre-imperial times. Before the time of the Yarlung dynasty, there were said to be 12 kingdoms or principalities. The Dak or Dakpo clan controlled one of these principalities called Dakyul Semo Druzhi. During Songtsen Gampo's time, the area the Dakpo clan lived in was part of Yoru. Now the area is part of Gyaza dzong and Lung dzong in the TAR. Gampopa Sonam Rinchen, also known as Dakpo Lhaje, was a prominent member of the Dakpo clan.
