[Sister Havana]

IU lost several sororities in the 90s (Alpha Sigma Alpha, Sigma Sigma Sigma, Sigma Kappa, and Alpha Omicron Pi), but AOPi recolonized in 2000 and IU hasn't lost any sororities since.

IU has lost loads of fraternities in the last few years...Theta Chi, Sigma Alpha Epsilon, Pi Kappa Alpha, Sigma Phi Epsilon, and Delta Chi are the ones I can think of offhand. Beta Theta Pi was gone for a few years but just recolonized.
