The notion of commitment is central to understanding agents and multiagent systems. At least two kinds of commitment can be identified in the AI literature---the internal or psychological and the external or social. While these notions must not be conflated with each other, they are not entirely unrelated. We review the historical development of commitments in AI and distributed computing, and show the various roles they might play in multiagent systems. We discuss the key interrelationships among these concepts, and study their implementational aspects, both in traditional individual agents, and in agents that are recursively created as systems of other agents. We close with a discussion of the key research challenges.
