The international community has long sent democracy aid, and technical election assistance (TEA) has become increasingly popular in the last three decades. Despite these investments, little is known about the effects of TEA. This master thesis focuses on how TEA affects violence during elections and asks if and how does technical election assistance prevent electoral violence in some contexts and not in others? I argue the TEA that is provided to both state and non-state actors in combination can reduce electoral violence. I argue that this can make elections credible and that credible elections are less probable to turn violent. By conducting case studies on Kenya, Nigeria, and Zimbabwe using Structured Focused Comparison, this thesis finds that the hypothesis when a state receives comprehensive technical election assistance, it will experience a reduction in electoral violence gets limited support. The findings show that TEA can help reduce violence since violence was reduced in all three cases, but only two of them received comprehensive TEA.
