What were the primary goals of the nativists?

During periods of increased immigration feelings of xenophobia tend to sweep the population.  Xenophobia is defined as a fear of foreigners.  This acrimony toward foreigners is what drove nativists in the United States at various times in history including the 1830s and 1920s.  The primary goal of nativists is to stop the flow of new immigrants to the host country.  The popular nativist sentiment is that a loss of culture is imminent when other cultural groups enter the country in large numbers.  Their perception is that the citizens that have been in the country the longest should have their interests protected above those that are just arriving.  A secondary goal of nativists is to celebrate or promote the qualities of the dominant culture.  Nativist organizations tend to be associated with racism and ethnocentrism.
