Followers of other religions like Zoroastrians and Hindus too were later integrated into the category of "dhimmis" and required to pay jizya. In the Indian Subcontinent the practice was eradicated by the 18th century. It almost vanished during the 20th century with disappearance of Islamic states and spread of religious tolerance. The tax is no longer imposed by nation states in the Islamic world, although there are reported cases of organizations such as the Pakistani Taliban and ISIS attempting to revive the practice.
