Islamic religious police (also sometimes known as morality police or sharia police) are official Islamic vice squad police agencies, often in Islamic countries, which enforce religious observance and public morality on behalf of national or regional authorities based on its interpretation of sharia. Modern Islamic religious police forces were first established in the late-1970s amidst the Iranian Revolution and the Islamic revival the revolution brought; prior, the administration of public morality in most Islamic countries was considered a socioreligious matter, and was enforced through application of civil laws or through more informal means.
