A stateless society is a society that is not governed by a state, or, especially in common American English, has no government. In stateless societies, there is little concentration of authority; most positions of authority that do exist are very limited in power and are generally not permanently held positions; and social bodies that resolve disputes through predefined rules tend to be small. Stateless societies are highly variable in economic organization and cultural practices.
While stateless societies were probably the norm in human prehistory, few stateless societies exist today; almost the entire global population resides within the jurisdiction of a sovereign state. In some regions nominal state authorities may be very weak and wield little or no actual power. Over the course of history most stateless peoples have been integrated into the state-based societies around them.
Some political philosophies, particularly anarchism, consider the state an unwelcome institution and stateless societies the ideal.
In archaeology, cultural anthropology and history, a stateless society denotes a less complex human community without a state, such as a tribe, a clan, a band society or a chiefdom. The main criterion of "complexity" used is the extent to which a division of labor has occurred such that many people are permanently specialized in particular forms of production or other activity, and depend on others for goods and services through trade or sophisticated reciprocal obligations governed by custom and laws. An additional criterion is population size. The bigger the population, the more relationships have to be reckoned with.
