Also known as People of the Book, dhimmis were people who shared the Bible with Muslims. Jews, who shared the Old Testament, were included, as well as Christians. When the Umayyads conquered Persia, they added Zoroastrians to the dhimmis. When they conquered India, they included Hindus and Buddhists, even though Hinduism, Buddhism, and Zoroastrianism did not shared the Bible. Dhimmis did have to pay the head tax on non-Muslims, but their communities were left intact and they were allowed to worship as they pleased.
