Geographical scholarship examining banal and everyday nationalism has tended to frame national flags as abstract and passive objects that are taken for granted and incorporated into the daily lives of citizens in mindless ways. In contrast, this paper acknowledges flags as lively material objects that can be enrolled by citizens to make political points and generate certain "affective atmospheres." It argues that the recognition of agency in debates concerning everyday nationalism needs to be pushed further to acknowledge the conscious and active negotiations of national objects like flags, to account for the diverse ways nations can be practised and performed by citizens. To illustrate our arguments we focus on the memories and reflections of citizens involved in protests in the Aysen region of Chilean Patagonia in 2012. During these incidents, citizens deployed different flags in provocative ways to draw attention to their reclamations and apply pressure on the Chilean state to improve socio-economic conditions in the region. The legacies of events like the 2012 protests and the associated (re)appropriation of national flags enables an interrogation of citizens' everyday identifications with nations in this border region of Patagonia. More broadly, we use the example to call for the materialities of flags as active objects to be the subject of further geographical inquiry, as one way to reinvigorate explorations of political agency and everyday nationalism.
