The first organization to use the term "sorority" was Gamma Phi Beta, established in 1874.The development of "fraternities for women" during this time was a major accomplishment in the way of women's rights and equality.
Phi Sigma Kappa's chapter home at Cornell, completed in 1902, is the oldest such house still occupied by its fraternal builders.
though fraternity-like organizations for women didn't take their current form until the establishment of Pi Beta Phi in 1867 and Kappa Alpha Theta in 1870.
The term "sorority" was invented by a professor of Latin who felt the word "fraternity" was inappropriate for a group of ladies.
Some of these organizations can accept graduate students as well as undergraduates, per constitutional provisions.
Fraternities and sororities engage in philanthropic activities; host parties; provide "finishing" training for new members, such as instruction on etiquette, dress, and manners; and create networking opportunities for their newly graduated members.
