Ganden Tripa
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.
