This thesis describes the evolution and demise of Oregon's alien land laws of 1923 and 1945 and their impact on the Nikkei community and the state's culture. After a brief discussion of Japanese immigration to Oregon and their lifestyle, the work discusses the emergence of discrimination against Japanese residents. At the same time, it outlines how the Nikkei adopted creative responses to the law. This thesis then explores the manner by which anti-Japanese internment policies during World War II shattered the Issei community, revoking many of the gains made in the previous half-century. The effects of the second alien land law and wartime economic changes in agriculture also are considered. The final section of the thesis deals with successful efforts in reversing the alien land laws and suggests how the Japanese experience in Oregon illustrates the challenges facing a pluralist society.
