The National Panhellenic Conference (NPC) is an umbrella organization for 26 (inter)national women's sororities throughout the United States and Canada. Each member group is autonomous as a social, Greek-letter society of college women and alumnae. The National Panhellenic Conference provides guidelines and resources for its members and serves as the national voice on contemporary issues of sorority life. Founded in 1902, NPC is one of the oldest and largest women's membership organizations, representing more than 4 million women at over 650 college/university campuses and 4,600 local alumnae chapters in the U.S. and Canada. Each year, NPC-affiliated collegians and alumnae donate more than $5 million to causes, provide $2.8 million in scholarships to women, and volunteer 500,000 hours in their communities. The organization holds a philosophy that it is a conference, not a congress, as it enacts no legislation and only regulates its own meetings. Other than basic agreements which its groups must unanimously vote to follow, NPC confines itself to recommendations and advice and acts as a court of final appeal in any College Panhellenic difficulty. One of its services is providing advisors for college and alumnae Panhellenic organizations. History Early histories of women's fraternities contain accounts of "rushing and pledging agreements" or "compacts" among fraternities on various campuses, and many stories of cooperation and mutual assistance. However, no actual Panhellenic organization existed and no uniform practices were observed. These stories date all the way back to 1891 with the intention to meet again in 1893. In 1902, Alpha Phi invited Pi Beta Phi, Kappa Alpha Theta, Kappa Kappa Gamma, Delta Gamma, Gamma Phi Beta, Delta Delta Delta, Alpha Chi Omega, and Chi Omega to a conference in Chicago on May 24 to set standards for collegiate sororities. Alpha Chi Omega and Chi Omega were unable to attend and would join the following year. The remaining seven groups met and the session resulted in the organization of the first interfraternity association and the first intergroup organization on college campuses. This meeting, and the next few, resulted in several mutual agreements, especially regarding pledging. Up to this time, no guidelines had been set, and women could be pledged to groups before enrolling in college and, indeed, even belong to more than one group. Many of the current members joined through the next decade, with Alpha Xi Delta in 1904, Alpha Omicron Pi and Sigma Kappa in 1905, Alpha Delta Pi and
