Right-wing populist, nationalist and extremist groups frequently make discursive use of the past to support their political agenda. This contribution briefly examines the use of the 1683 Siege of Vienna in political discourses. It shows how certain parts of European heritage are mobilised globally to present a singular view of European identity as white and Christian. This identity is constructed in opposition to a Muslim and migrant ‘other’. The contribution shows that this notion of European identity is used not as a call for European unity, but to serve nationalistic needs when utilised by far-right groups. Moreover, this piece calls for greater recognition of how heritages are mobilised across borders in the interests of advancing a politics of exclusion and division.
