This article argues that negotiation agendas in peace processes are good indicators for the presence of factors that lead to success in the attempt to put an end to armed conflicts. While the literature suggests a series of psychological and contextual elements that may help to explain the outcome of a peace process, this article demonstrates the utility of incorporating the agendas as part of a systematic study. Hence, it presents results of the analysis of 83 peace processes occurred between 1989 and 2012, describes the technical and political topics discussed between the parties, and identifies trends in terms of duration, geography, nature of conflict, and outcomes. Finally, it shows that discussion of topics such as transformation of rebel organizations into political parties, or their integration into the national armed forces, are related to a higher probability of success in the process.
