First page of the Constitution of the Adelphian Society.
Gamma Phi, the first college literary society at Colgate University formed around 1833, was incorporated into the Adelphian Society.
The Adelphian Society was founded on October 31, 1840, at the Hamilton Literary & Theological Institution, today Colgate University. The purpose of the Aldelphian Society was to “progress in literary attainments and cultivation among all the members of an undecaying friendship."
In 1850, five members of the Adelphian Society at Colgate transferred to the newly created University of Rochester and founded the Delphic Society.
The Adelphian Society at Colgate University eventually evolved into the Beta Theta Chapter of Beta Theta Pi Fraternity.
