The student body of Johns Hopkins University has grown increasingly diverse with students from all backgrounds joining the community each year. Minority and international students introduce fresh ideas, enriching Hopkins with their distinct perspectives and experiences. Moreover, the minority and international students have engaged in different activities under influence of historical trends. It is fascinating to trace how both the group-specific identity and the contemporary tide have shaped the activities of the minority and international student groups. We will explore the Iranian Student Association in the 1970s, the Jewish Student Association in the 1970s and 1980s, the Chinese Student Association in 1980s and 1990s, and the Black Student Union in the 1990s as remarkable cases of student involvement.
