Non-state describes a stakeholder or force in a debate or conflict in which sovereign states and international organizations are the major and minor parties, respectively. Non-state can refer to anything that is not affiliated with, supported by, or connected directly to a sovereign state or one of its governmental organizations, including in international commerce. Non-state may also refer to groups that are unincorporated within a particular state, or are unknown to the state or nation they are within.
