Ashoka sent missionaries to Tibet and Ceylon.
Ashoka was an ancient Indian emperor of the Mauryan dynasty who ruled from 268 to 232 BCE. He is known for his role in spreading Buddhism across India and other parts of Asia. As part of his efforts to promote Buddhism, Ashoka sent missionaries to various regions to spread the teachings of the Buddha. The two regions where he sent missionaries were Tibet and Ceylon (modern-day Sri Lanka). These missions were successful in spreading Buddhism in these regions, and they played a key role in the growth and development of Buddhism in Asia.
