Anarcho-tribalism is a type of anarchist ideology and social system, in which there is little or no central government, and individuals form voluntary associations with eachother so as to form self-governing tribes.
Anarcho-tribalism must not be conflated with anarcho-primitivism, though the two can be combined. In an anarcho-tribalist system, a given tribe may have any level of technology, unless otherwise stated.
 Usage by so called "nationalist anarchists"
Anarcho-tribalism or ethnic tribalism is a term heavily employed by self-titled, third positionist "national anarchists", nazis that take the guise of a anarchist movement as part of a political tactic of entryism and propagating racism on a tribal basis. Sadly, this also shows that there are dangerous intersections in the antimodernist thinking of some anarcho-primitivists and far-right ideologies, both sharing the imagination of a idealized past compared to the often confusing-seeming present. http://en.wikipedia.org/wiki/National-Anarchism
