Two decades after the third wave of democratization', extensive violence continues to follow elections in sub-Saharan Africa. Whereas national processes connected to pre-election violence have received increased scholarly attention, little is known of local dynamics of violence after elections. This article examines the 2011 Nigerian post-election violence with regard to the ways in which national electoral processes interweave with local social and political disputes. The most affected state, Kaduna State, has a history of violent local relations connected to which group should control politics and the state. It is argued that electoral polarisation aggravated national ethno-religious divisions that corresponded to the dividing line of the conflict in Kaduna. A rapid escalation of violence was facilitated by local social networks nurtured by ethno-religious grievances.
