In this approach to an understanding of America's ethnic minorities, the most important concern is with the interaction between these various culture groups and the dominant, white society. Six of America's principal ethnic minorities have been considered: blacks, Mexicans, Indians, Chinese, Japanese, and Puerto Ricans. In each case the same procedure was followed to determine the roles they have played in the development of today's American culture. The material presented is to be considered as a "starting point" for one who is interested in further research. The line of inquiry was set up in this manner: firstly, the historical and cultural background of the minority was covered briefly; secondly, what were the circumstances under which the ethnic group first came to America, and then spread out?; thirdly, what is their religious background?; fourthly, what are the signs of the visible imprint of this ethnic minority and its culture elements upon the culture and cultural landscape of the United States?; and, finally, what role will this ethnic minority play in the future economic, political, social, and religious life of the United States?
