Mass conversion refers to the process where a large group of people adopts a new belief system or religion simultaneously. This phenomenon can occur for various reasons, including social, political, or economic pressures, and often involves significant cultural shifts. Historical examples include the mass conversion of entire communities during the spread of Christianity or Islam. Such conversions can have profound effects on society, influencing traditions, laws, and interpersonal relationships. They may also lead to conflicts, especially if the new belief system clashes with existing cultural practices. Understanding mass conversion helps in studying the dynamics of religious change and its impact on communities.
