Each of the nine (9) NPHC organizations evolved during a period when African Americans were being denied essential rights and privileges afforded others. Racial isolation on predominantly white campuses and social barriers of class on all campuses created a need for African Americans to align themselves with other individuals sharing common goals and ideals. 

With the realization of such a need, the African American (Black) Greek-lettered organization movement took on the personae of a haven and outlet, which could foster brotherhood and sisterhood in the pursuit to bring about social change through the development of social programs that would create positive change for Blacks and the country. Today the need remains the same.

The primary purpose and focus of NPHC member organizations remains community awareness and action through educational, economic, and cultural service activities.Greek membership goes beyond your collegiate experience.

“This is a Lifetime Commitment!” The individual member is expected to align with a graduate/alumni chapter, following graduation from college, with the expectation that he/she will attend regular chapter meetings, regional conferences and national conventions, and take an active part in matters concerning and affecting the community in which he or she lives.

NPHC promotes interaction through forums, meetings and other mediums for the exchange of information and engages in cooperative programming and initiatives through various activities and functions.
