A siida is an organisation of humans traditionally present in Sámi societies consisting of several families of reindeer herders whose reindeer graze together.[1]: 107–109 [2] Siidas traditionally encompassed more resources than reindeer,[1]: 108 but after changes in Sámi societies over the course of the 1600s, only reindeer herders still practiced this system.[3]: 68 It is termed a sameby ('Sámi village') in Swedish law, reinbeitedistrikt ('reindeer pasture district') in Norwegian law, and paliskunta ('reindeer herding district') in Finnish law. The pastoralist organisation differs slightly between countries, except in Russia, where kolkhoz replaced these earlier organisations.
