The Karma Kagyü (karma bka' brgyud) sect was founded by Düsum Khyenpa (dus gsum mkhyen pa, 1110-93) who founded Tsurpu (mtshur phu) Monastery in 1185. He was a disciple of Gampopa. The "Karma" suborder is probably named after the monastery of Karma Densa (karma gdan sa) which he already founded earlier in eastern Tibet, his home province. The Karma Kagyü became one of the most important and powerful of Tibetan sects, and was very politicized in the various religious conflicts transpiring in Central Tibet. The line of incarnations descending from Düsum Khyenpa came to be known as the Karmapas (currently in its seventeenth reincarnation), and developed into one of most famous and powerful of Tibetan trülkus (institutionalized reincarnate lamas, sprul sku).
