A mode of negotiation in which a mutually acceptable third party helps the parties to a conflict find a solution that they cannot find by themselves. It is a three-sided political process in which the mediator builds and then draws upon relationships with the other two parties to help them reach a settlement. Unlike judges or arbitrators, mediators have no authority to decide the dispute between the parties, although powerful mediators may bring to the table considerable capability to influence the outcome. Mediators are typically from outside the conflict. Sometimes mediators are impartial and neutral, in other cases they have a strategic interest that motivates them to promote a negotiated outcome. Mediators may focus on facilitating communication and negotiation but they also may offer solutions and use leverage, including positive and negative incentives, to persuade the parties to achieve an agreement.
