Social movement studies have addressed the issue of nostalgia within two perspectives, focusing, respectively, on emotions and on memory. Our contribution looks at nostalgia in social movements by building upon the combination of these two streams in social movement studies. Going beyond a stereotypical vision of reactionary movements as backward looking and progressive ones as forward looking, we will suggest that while both types of movements look at some aspects of the past with nostalgia, they do it in a very different combination of emotions and memory. To compare how different movements perform their emotional and memory work, we focused on the recent uprising in Lebanon as a critical case in which mobilizations and counter‐mobilizations have been carried out by different actors at the same time. In both cases, nostalgia was strategically developed for different moments of Lebanon's history through the movements' choices of the very spaces for the performance of contentious acts, but also the symbolic meaning attributed to them and the emotional work performed around the protest events. By developing a “tick description” of some main contentious moments where nostalgia emerged in the Lebanon uprisings, we aim to understand the ways in which nostalgia intervenes in the social construction of memories and counter‐memories, in an emotionally dense environment.
