Toward the end of the summer of 1998, two University of California Riverisde students, Jet Tantibanchachai and Jun Tamoro already rushed and pledged for a few fraternities their Freshman year. While pledging other Fraternities the two witnessed the assassination of character and dignity in exchange for Fraternity pride. Together, they formed a new vision of a Brotherhood that would not be categorized by race or image but the quality of a true brotherhood that will not be tainted. That culminated into the Brothers of the Underground Denomination. The protest of the other organization practices are summed into three words – Keeping it Real; the idea that a person does not have to turn into another person to be part of an organization. Together, they were able to get 19 other students who related to the experiences, 7 who attended the California State University Fullerton to establish the brotherhood known today as BUD, or Beta Upsilon Delta.
The road in establishing credibility within the college community was met with much difficulty and resistance because of three main factors: the refusal of being a part of a council, the so-called unorthodox practices of the Fraternity, and the name itself. Despite the resistance, the brothers of Beta Upsilon Delta pushed themselves harder to carve a niche in the Greek Lettered community, and eventually became one of the more well known Fraternities on the campus of UC Riverside today.
During the end of 2001, Beta Upsilon Delta established their newly formed Beta chapter in California State University, Fullerton.
