This study considered the experiences of graduate sorority women in Black Greek-lettered organizations (BGLOs) with social activism, using contemporary examples like Black Lives Matter as a lens. BGLOs exist as part of the fraternity and sorority framework at predominantly White institutions (PWIs). These organizations provide networking, leadership opportunities, and connection for African American students and students from the African diaspora. BGLOs contribute to mainstream persistence and retention strategies by creating educational and social programs that connect to popular culture and engage the campus community. This exploration of graduate Black BGLO women and their perceptions of social activism provided an opportunity to consider another dimension of the experiences of Black sorority women through the lens of their undergraduate membership. Understanding the arc of their membership stories and lifelong commitment to their organizations can encourage PWIs to create meaningful long-term graduate engagement opportunities that will benefit their institution and communities, locally and nationally.
