The Drukpa or Drukpa Kagyu (འབྲུག་པ་བཀའ་བརྒྱུད) lineage, sometimes called Dugpa in older sources, is a branch of the Kagyu school of Tibetan Buddhism. The Kagyu school is one of the Sarma or "New Translation" schools of Tibetan Buddhism. The Drukpa lineage was founded in the Tsang region of Tibet by Tsangpa Gyare (1161–1211), and later became influential in Ladakh and Bhutan. It is one of several lineages known as "Red Hat sects".
Within the Drukpa lineage, there are further sub-schools, most notably the eastern Kham tradition and middle Drukpa school which prospered in Ladakh and surrounding areas. In Bhutan the Drukpa lineage is the dominant school and state religion.
The Drukpa lineage was founded in the Tsang region of Tibet by Tsangpa Gyare (1161–1211), a student of Ling Repa, who mastered the Vajrayana practices of the mahamudra and Six Yogas of Naropa at an early age. As a tertön or "finder of spiritual relics", he discovered the text of the Six Equal Tastes, previously hidden by Rechung Dorje Drakpa, the student of Milarepa. While on a pilgrimage, Tsangpa Gyare and his disciples witnessed a set of nine dragons (Tibetan: druk) roaring out of the earth and into the skies, as flowers rained down everywhere. From this incident they named their sect Drukpa.
Also important in the lineage were the root guru of Tsangpa Gyare, Ling Repa and his guru, Phagmo Drupa Dorje Gyalpo, who was in turn a principal disciple of Gampopa as well as Dampa Sumpa, one of Rechung Dorje Drakpa's main disciples.
A prominent disciple of Tsangpa Gyare's nephew, Onre Darma Sengye, was Phajo Drugom Zhigpo (1208–1276) who in 1222 went to establish the Drukapa Kagyu teachings in the valleys of western Bhutan.
The disciples of Tsangpa Gyare Yeshi Dorje (1161–1211), the first Gyalwang Drukpa, may be divided into two categories: blood relatives and spiritual sons. His nephew, Onre Darma Sengye (1177–1237), ascended the throne at Ralung, the main seat of the Drukpa lineage.
