Now I’m not 100% sure of this because I’m working from memory, but I think Kropotkin gave examples for this in “Mutual aid”.

For Eskimos he mentions that anything an individual catches or gathers belongs to the clan as a whole, and then it is redistributed. People living in tribes (with no concept of a separate family) generally live ‘each for all’.

Village communities, on the other hand, recognized only movable property as privately owned, while land belonged to the community, and everything had to be done with the consent of the community.

When disputes did arise, they were treated as communal affairs and mediators were found to pass a resolution. If the resolution was not agreeable to one party, the case would go before the folkmoot and the decision reached was final. The party that had to provide some reparation could either accept, or leave the village and go somewhere else, but there were no law enforcers.

A little less rosy than Kropotkin, and not really anarchist, but Icelanders lived without a state until the late 13th century. They had a (bi)yearly gathering (the “Thing”) where all grievences could be brought forth before the judges and people. When a sentance was passed, it was up to the family of the ‘winner’ to see that the other side accepted it, there was no state figure to force them.
