Indigenous people of Kamchatka were placed under the Russian Empire system after the arrival of Atrasov’s army in 1697. The second strong influence was the establishment of the Soviet Union and its socialism economy. As the main industrial section of collectivization, reindeer-herding was introduced to indigenous society of Siberia including Kamchatka in 1930s. As another productive section, fishery was also introduced. Indigenous people were forced to move from their home settlements to new large settlements. Collectivization and reorganization of settlements can be taken as “modernization” of life and most of the people affirmatively received this collectivization, because this policy offered education, residents, food, new jobs and so on to these people. However, reorganization of settlements followed by collectivization also had negative influences. Reorganization had harmful influence on traditional custom and social system of indigenous society. In this paper I would like to examine the influence of collectivization and reorganization of settlements depicted from interviews to indigenous people mainly in Karaginsky region, Tigil’ region and Bystol region.
