Islamist Shi'ism is a form of the Islamic religion, which follows the teachings of the Prophet Muhammad and his family. It is especially popular in countries like Iran, Iraq and Lebanon. Islamist Shi'ism says that Muslims should follow a strict interpretation of Islamic law and follow the teachings of the clergy. This means that women have to cover up more, and that certain activities are not allowed. It also says that governments should be run according to Islamic law and not according to man-made laws.
