Kadam (Tibetan Buddhism) in the context of "Kagyu"

The Gelug (/ɡəˈluːɡ/, also Geluk; lit. 'virtuous') is the youngest of the four major schools of Tibetan Buddhism. It was founded by Je Tsongkhapa (1357–1419), a Tibetan philosopher, tantric yogi and lama and further expanded and developed by his disciples (such as Khedrup Je, Gyaltsap Je, Dulzin Drakpa Gyaltsen, and Gendün Drubpa).

The Gelug school is alternatively known as Kadam (bKa’-gdams gsar-pa), since it sees itself as a continuation of the Kadam tradition of Atisha (c. 11th century). The school of New Kadam, or New Kadampa is an offshoot of the Gelug-tradition. Furthermore, it is also called the Ganden school, after the first monastery established by Tsongkhapa. The Ganden Tripa ("Ganden Throne Holder") is the official head of the school, though its most influential political figure is the Dalai Lama ("Ocean Teacher"). Allying themselves with the Mongol Khans, the Gelug school emerged as the dominant Buddhist school in Tibet and Mongolia since the end of the 16th century (religiously and politically). Another alternative name for this tradition is the Yellow Hat school or sect.

Atish Dipankar Shrijnan (Sanskrit transliteration: Atīśa Dīpaṅkara Śrījñāna) (c. 982–1054 CE) was a Bengali Buddhist religious teacher and leader. He is generally associated with his body of work authored at Vikramaśīla Monastery in modern day Bihar, India. He was a major figure in the spread of 11th-century Mahayana and Vajrayana Buddhism in Asia and traveled to Sumatra and Tibet. Atiśa, along with this chief disciple Dromtön, is regarded as the founder of the Kadam school, one of the New Translation schools of Tibetan Buddhism. In the 14th century, the Kadam school was supplanted by the Gelug tradition, which adopted its teachings and absorbed its monasteries.

Khedrup Gelek Pelzang, 1st Panchen Lama (1385–1438 CE) – better known as Khedrup Je –  was one of the main disciples of Je Tsongkhapa, whose reforms to Atiśa's Kadam tradition are considered the beginnings of the Gelug school of Tibetan Buddhism.

Khedrub Je is considered to be an emanation of Manjusri, the Buddha of Wisdom.
