甘丹赤巴
Jangchub Gyaltsän (1302–1364) became the strongest political family in the mid 14th century. During this period the reformist scholar Je Tsongkhapa (1357–1419) founded the Gelug school which would have a decisive influence on Tibet's history. The Ganden Tripa is the nominal head of the Gelug school, though its most influential figure is the Dalai Lama.
