Social fraternities are organizations typically found on college and university campuses, primarily in the United States. They focus on fostering brotherhood among members, promoting social activities, and providing networking opportunities. Members often participate in community service, philanthropy, and various events that enhance their college experience. These fraternities usually have a Greek-letter name and are part of a larger system that includes sororities, which are similar organizations for women. Each fraternity has its own traditions, values, and membership requirements, and they often engage in recruitment processes to attract new members. Notable examples include Sigma Chi and Kappa Alpha Order.
