Alpha Kappa Psi (ΑΚΨ, often stylized as AKPsi) is the oldest and largest business fraternity to current date.

As the spirit of brotherhood grew stronger in the hearts and in the minds of the men from Brooklyn, they decided to suggest to the other members of their class that something be done to perpetuate it.

They received hearty support from the men approached regarding their idea, and by the end of April 1904, things were beginning to take definite shape.

Before the academic term came to a close, a date was set for a meeting to take place at the Hotel Saint Denis in which a plan for the organization would be outlined.

On June 9, 1904, The Brooklyn Four were joined at the Hotel St. Denis by Robert S. Douglas, Irving L. Camp, Daniel V. Duff, Morris S. Rachmil and Herbert M. Wright.

On July 16, 1904, a group of them traveled by steamer to Sea Cliff, Long Island and, at this meeting, the draft of the constitution was presented.

The social aspect of the fraternity was emphasized early on, as Jefferson later recounted, "The greater part of the day, however, was spent in having summer fun, and although the party did no real work on the constitution, yet the friendships were strengthened."

At the 1950 Alpha Kappa Psi Convention in Minnesota, delegates voted 66–44 in favor of dropping the restrictive membership clause from the national constitution.

[5] In June 1972, Title IX of the Education Amendments Act of 1972 was passed and it brought the beginning of the most significant change in the history of Alpha Kappa Psi.

Title IX prohibited sex discrimination in federally assisted educational programs and amended parts of the Civil Rights Act of 1964.

Delta Chi went on to elect a female president and attempted to send her to the 1974 national convention as their voting delegate.

"[6] In December 1973, a complaint was filed with the Office of Civil Rights of the Department of Health, Education and Welfare against thirteen colleges and universities which recognized professional business fraternity chapters.

In March 1973, representatives of several organizations formed to push for legislation that would exempt the groups from Title IX as it applied to professional fraternities.

Out of these meetings, the Fraternal Alliance for Inalienable Rights (FAIR) was formed, which included Alpha Kappa Psi.

At the national convention, the Committee on Female Membership moved that the fraternity should bar women, advocating a continuance of the struggle to secure legislation.

The 1975 convention voted the board of directors the authority to change Article III, Section 1 of the Constitution by deletion of the words "must be men and", if no legislative recourse could be achieved.

Even though an expansion to London seemed like just a matter of time, as it is the business capital of the world, it finally happened after 16 years from the date of approval of the Manchester chapter.

The installations were led by president Alexander Sultan, executive VP Mike Dickerson, chief operating officer Brian Parker, regional director Jason Weinstein and many volunteers and alumni brothers.

In March 2013, a colony of Alpha Kappa Psi was established at the Hong Kong University of Science and Technology.

The board of directors is the supreme legislative, judicial and oversight body of the fraternity outside of meetings of the chapter congress (held every two years at the convention).

The Principled Business Leadership Institute (PBLI) is an annual weekend program held each February in five cities across the United States.

In addition to the educational leadership development tracks, the fraternity's Case Competition also takes place during PBLI.

PBLI began in 2009 as a retooled and updated version of the fraternity's similar Success Institute, which was originally introduced in 1996.

Facilitators include fraternity staff and volunteer leaders, successful alumni members and special guests from the business community.

Howard M. Jefferson chaired the editorial committee that published the original four page monthly pamphlet of the Alpha chapter.
