What are the branches of Zoroastrianism?

Zoroastrianism primarily has two main branches: the Parsis and the Iranis. The Parsis, who migrated to India, are the more prominent group outside Iran and have maintained a distinct cultural and religious identity. The Iranis, on the other hand, remained in Iran and have preserved their traditions amid the challenges of modernity. Both branches share core beliefs in Zoroastrian teachings but may differ in cultural practices and rituals.
