Abstract Differential participation in violent protests has been explained in terms of protesters’ personal values, biographical availability, and network embeddedness. However, the form of mass protest may be influenced less by the microstructure of protesters and more by their collective past experiences of resistance. Through the South Korean candlelight protests of 2008 and 2016–2017, this article examines novices’ and repeaters’ perceptions of nonviolent protest. Onsite survey and interview data show that previous frustrating protest experiences in 2008 made repeater protesters more perseverant, even when violence was expected. Repeaters had little faith in “disciplined” protests, whereas novices hoped for change through “peaceful” protests. I argue that previous experiences of resistance and their outcomes influenced protesters’ perceptions on the efficiency and legitimacy of violent protest. By examining protesters’ varying perseverance, which mediates the condition of violence, this article advances the relationship between violence and civic participation.
