Ukraine’s efforts to resist the Russian invasion have sparked unprecedented levels of civic engagement. While the more tangible efforts to alleviate immediate needs have been prominently featured in mass media and elsewhere, the norms and values that shaped this large-scale collective effort often remain behind the scenes. Approaching narratives of volunteering through a critical cultural sociology lens, we find that wartime involvement constitutes a shift from duty-based norms in which citizens are required or expected to engage in civic activities, to forms of engaged citizenship which contribute not just to the state, but also to the wellbeing of those in need. In this context, volunteering facilitates the emergence of civil society that often occupies the space outside of the currently defined institutional contexts and works through the collective shaping and contestation of social norms and values. Documenting these dynamics provides valuable new insights into the important role volunteerism plays in broader sociopolitical transformations, especially in non-Western and postcolonial contexts where the processes of civil society development take many forms and may be easily overlooked.
