The role of the private sector in different aspects of conflict resolution has received increasing attention in recent years. This paper discusses the diverse roles played by the private sector during Track 1 peace processes in particular, drawing on a variety of examples from different contexts. The examples illustrate that where the private sector enjoys credibility (sometimes higher than state parties), has access to conflict parties, and a strategic interest in the resolution of a conflict, it can become actively involved and have significant impact on the course of a peace process, for better or worse.
