This chapter discusses the emerging historiographies of performance art in East-Central Europe, where the genre developed during the communist period outside of the official spheres of art. It looks at the range of ways in which performance was codified—for example, artists’ self-archivization, exhibitions, and festivals. It also explores the recent publication of national and comparative histories, and the methods used to amass this history, including interviews with the artists. This chapter makes the case that the historiography of performance art in East-Central Europe developed in alternative spaces and media in the same manner that the genre itself did.
