I want to know the answer to the following question:
Who founded the Gelug school?
All the background I'm provided with is that "The following 80 years saw the founding of the Gelug school (also known as Yellow Hats) by the disciples of Je Tsongkhapa, and the founding of the important Ganden, Drepung and Sera monasteries near Lhasa.". Is that enough to answer the question?
Answer: yes
