Siida

This custom originates in older conventions when reindeer were used by settled local populations in daily life.

Based on historic Swedification policies that distinguished between settled and nomadic Sámi, membership in Swedish siidas is essentially limited to those whose ancestors were nomads before 1886, barring the majority of Swedish Sámi from membership in a siida.

[2][4][5] Prior to the act, Norwegian authorities maintained their own definitions of reindeer herding districts, leading to piecemeal development and sales of land, disconnecting traditional pasture areas.

[7] In Russia, Arctic peoples were forcibly relocated to kolchozes (collective communities) by the state between 1927 and 1940, including the Sámi of the Kola Peninsula.
