This chapter considers how the historical and contemporary geopolitics of Polish memory intersect in the commemoration of the end of the First World War in Poland. Using an innovative digital ethnographic approach, it shows how contemporary national identity is articulated on 11 November, the day that also marks Polish Independence Day. These historical and political narratives intersection in a major nationalist march that the author attends in Warsaw, when nationalist groups use the date to buttress an extremist version of Polish national identity based on ‘independence regained’. Moreover, she shows how digital technologies are implicated in this event, both as a means of doing research, and as a guarantee of the march’s longevity in the digital realm long after the event itself is over.
