Fraternities are social organizations, primarily found in North American colleges and universities. They are often single-sex, with the majority being male. These organizations trace their origins back to the Enlightenment period and the development of secret societies in academic settings. The fundamental purpose of a fraternity is to foster brotherhood and personal development among its members. This typically involves a shared living experience in a fraternity house, as well as a structured membership process that often includes pledging or new member education. Activities within fraternities commonly include social events, philanthropic endeavors, academic support, and leadership training. Membership is usually by invitation and requires a vote of approval from existing members. While often associated with college life, fraternity alumni networks can extend throughout a member's professional career. The specific rituals, traditions, and organizational structures vary significantly between different fraternities, each having its own unique history and values. The Greek alphabet is frequently used in the names of these organizations, leading to the common term "Greek letter fraternities."
