The Tselpa Kagyu tradition, one of the four major lineages of the Kagyu tradition, was founded in the twelfth century by Zhang Yudrakpa, also known as Lama Zhang. The seat was at Tsel Guntang, north of Lhasa. Important figures include Dungtso Repa Sherap Gyeltsen who revealed teachings of Gampopa. The tradition was absorbed by the Geluk school in the fifteenth century and its monasteries were converted.
