Religious fundamentalism refers to a strict adherence to specific beliefs and practices within a religion, often emphasizing a literal interpretation of sacred texts. This movement can be found in various faiths, including Christianity, Islam, and Hinduism, and typically seeks to return to what adherents consider the original principles of their faith. Fundamentalists often resist modern influences and changes in society, viewing them as threats to their beliefs. This can lead to a desire for political power to enforce their values, sometimes resulting in conflict with other groups or ideologies that promote different interpretations or secularism.
