Prior to 1917, the school had national organizations that were forced to close when the Board made the decision to eliminate Greek life.

The oldest local sorority on campus, Pi Kappa, was founded in 1918 and started as a social group called the Peanuts. The TTK founders were the remaining members of the Kappa Kappa Gamma Beta Gamma chapter, originally founded in 1876. The other NPC groups also formed locals but only one group can trace their history all the way back. The others have come and gone over time.

The oldest fraternity on campus was also founded in 1918, by the members of the Alpha Lambda chapter of Beta Theta Pi.

Wooster?

Not super old, but the local at my undergrad was founded in 1921.
