250 BC-200 BC (Sad Macedonia)

Spread of Buddhism
Ashoka sent scholars to convert people to Buddhism. One of the reasons he converted to Buddhism was to convert the Hindus and Zoroastrians to establish a unified empire. This was highly successful and by 215 BC, although religious freedom was maintained, Zoroastrianism and Hinduism were minority religions in the Maurya Empire. Soon, scholars were sent to Southeast Asia, which was part of the Maurya zone of influence, and Buddhism would grow there as well.
