The first student government body was founded at Lehigh in 1904. Known as Arcadia, it aimed to uphold the honor code and promote student activities. Representatives initially came from campus organizations and sports teams and later from fraternities and residence halls.  Eventually, students came to feel that they were not being heard by administrators, and in 1970, the group disbanded.

Students protested to demand greater input in university activities and decision-making, and subsequently, the Forum was formed. At first, the body had equal representation from students and faculty. But in 1988, with enthusiasm lacking and the groups not coming together as intended, its members voted to split into faculty and student groups. The Student Senate was established to address student issues and to recognize and allocate funds to clubs. 

Student Senate XXVIII was recently formed for the 2015-16 school year. It will continue to deal with diversity and inclusion, safety, transportation on campus and other topics.
