Final answer:
The Union Triad consists of Kappa Alpha Society, Sigma Phi Society, and Delta Phi Fraternity, established at Union College in the early 19th century and recognized as the earliest examples of modern college fraternities.
Step-by-step explanation:
The Union Triad is comprised of three fraternities that were established at Union College in Schenectady, New York. These fraternities include Kappa Alpha Society (1825), Sigma Phi Society (1827), and Delta Phi Fraternity (1827). The Union Triad is significant as they are recognized as the earliest forerunners of modern-day college fraternities, setting traditions and structures that would be emulated by later organizations.
It is important to distinguish these fraternities from other Greek organizations founded later, such as those that fall under the National Pan-Hellenic Council, which oversees nine International Greek fraternities and sororities. Additionally, historically Black fraternities and sororities, like Alpha Kappa Alpha Inc. founded at Howard University, play a distinct role in their communities and have notable members across various fields.
