I want to know the answer to the following question:
Who eradicated the Sakya viceregal regime?
All the background I'm provided with is that "In 1358, the Sakya viceregal regime installed by the Mongols in Tibet was overthrown in a rebellion by the Phagmodru myriarch Tai Situ Changchub Gyaltsen (1302–1364).". Is that enough to answer the question?
Answer: yes
