Final answer:
The previous name of the ZBT chapter Rho was Kappa Nu fraternity before the merger that formed the current ZBT fraternity.
Step-by-step explanation:
The previous name of the ZBT chapter Rho was initially Kappa Nu fraternity before the two organizations merged. ZBT, or Zeta Beta Tau, is a historically Jewish fraternity that was founded in 1898 and has undergone several changes and mergers throughout its history. Kappa Nu was a Jewish fraternity that was established in 1911. It merged with Phi Alpha Pi, Phi Sigma Delta, and Phi Epsilon Pi to form the larger ZBT fraternity we know today, which officially happened in 1969-70. The merger included the assimilation of their respective chapters, hence Kappa Nu's Rho chapter became part of ZBT.
