I want to know the answer to the following question:
When was Gelug was given the right to conduct the New Years prayer?
All the background I'm provided with is that "However, it was not until 1518 that the secular Phagmodru ruler captured Lhasa from the Rinbung, and thereafter the Gelug was given rights to conduct the New Years prayer.". Is that enough to answer the question?
Answer: yes
