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 modernity and secular influences, believing that their religious values should guide all aspects of life, including politics and social issues. This can lead to a desire for societal change based on religious principles, sometimes resulting in conflict with differing beliefs or lifestyles.
