Abstract On 4 March 2013, when Kenyans participated in national presidential and legislative elections, there was wide-spread concern that the underling grievances that erupted during the 2007 and 2008 post-election violence would remerge. However, the polls were relatively peaceful in comparison. This case study will interrogate how mass atrocities were prevented in 2013 in Kenya, despite the prevalence of risk factors which could spark tensions and fuel violence. This article interrogates the local sources of resilience and inhibitors of atrocity crimes and considers the preventive actions that were undertaken and by whom, with a view to understanding what they achieved. In addition, it will assess the outcomes that were achieved as a result of these preventive actions. Through an evaluation of the preventive actions the article will examine which actions proved to be most effective in affecting the risks dynamics of the country in the short, medium and long-term. Kenya’s history of violence and failure to uphold accountability and redress for victims, meant that in 2013, it was significantly prone to the scourge of atrocity crimes. This analysis will draw out a number of key lessons for enhancing the prevention of atrocity crimes in the future.
