In anthropology, an acephalous society (from the Greek for "headless") is a society which lacks political leaders or hierarchies. Such groups are also known as egalitarian or non-stratified societies. Typically these societies are small-scale, organized into bands or tribes that make decisions through consensus decision making rather than appointing permanent chiefs or kings. Most foraging or hunter-gatherer societies are acephalous. Modern anarchist and libertarian socialist societies that have abolished social inequality (e.g Freetown Christiana, Anarchist Catalonia and the Kibbutz) may be considered acephalous as well.
