In this article, I bring together the archive of institutional activism of Niara Sudarkasa in the U.S. and the posthumous impact of activist and public administrator Marielle Franco. The 1970s historical sources show Sudarkasa’s institutional solidarity with students and faculty in the creation of one of the first Africana Studies departments in the U.S. Reading them, I articulate an ethos for the curation ‘715 Haven Street: Art Looks Back,’ a public digital art gallery comprised of art and (...) history found in the DAAS Papers (Department of Afroamerican and African Studies) housed in the Bentley Library’s digital and physical archives. The analysis of the primary sources is guided by an engagement with the ‘Marielle Effect,’ generating a historical parameter for Abolitionist solidarity between American, Brazilian, Latin American, African American, Diasporic, and ally scholarly communities. The discussion of these parameters is embedded in my discussion of the concept of pacification, a phenomenon of colonial and post-colonial policing that survives through the perpetuation of an extra-judicial policing impetus articulated along race, identity, legality, and sexual legitimacy of subjects.
