This chapter analyses the dialectic of cultural memory and political solidarity in Three Saplings on the Gallows (Darağacında Üç Fidan) by the Turkish socialist writer Nihat Behram. First published in 1976 to commemorate the 1972 executions of the Marxist-Leninist revolutionaries Deniz Gezmiş, Hüseyin İnan, and Yusuf Aslan, Three Saplings on the Gallows constitutes one of the most widely circulated life narratives in the history of the Turkish left, undergoing its 125th print in 2022 despite being banned for two decades. Situating the book as relational life writing and as a “portable monument” in Turkey’s leftist memory culture, I argue that Behram’s commemoration of these figures’ lives constitutes activist memory work that conceptualises and practices remembrance as a foundation for political solidarity, establishing memory work as solidarity work. Situating memory work as auto/biographical, I first trace how Behram conceptualises witnessing as a way of forging solidarity through self-reflective acts of remembrance. Then, I examine the ways in which Behram’s own life narrative was inscribed into later editions of the book through paratextual additions to evidence his solidaristic self-sacrifice. I argue that the book’s formative role in left-wing cultural memory in Turkey relies on its conceptualisation and defiant practice of bearing witness to the deaths of ‘three saplings’ as a form of building and sustaining political alliance.
