10 Oldest Fraternities in North America

Fraternities are a staple of college life in America and their practices are often referenced in today’s popular culture. While the earliest fraternities may not exactly resemble their modern counterparts, their core beliefs have been passed down.

The very first Greek-letter society was formed in 1775 and influenced what are considered the first modern college fraternities that popped up in the early 19th century. These first fraternities established the model for the fraternities that came after and they are still active nearly 200 years later.

Chi Psi was founded at Union College in 1841 with the idea of emphasizing the fraternal and social principles of a brotherhood. This was the first fraternity to emphasize these qualities over literary and scholastic characteristics of other earlier fraternities. It was the fifth ever fraternity started at Union College and the four older fraternities from Union College are also on this list.

Like many fraternities, Chi Psi has had its fair share of controversies over the years. In 2004, a pledge died from alcohol poisoning and members of the chapter had drawn slurs all over his lifeless body. The chapter was only temporarily suspended. The pledge’s death received national media coverage, which highlighted how fraternities continue to operate like nothing happened even after a death.
