Thorsten Sellin would likely view the replacement of Native American norms by those of English settlers as an example of ____________.

Thorsten Sellin introduced the concept of culture conflict, which he categorized into primary and secondary culture conflicts. Primary culture conflict specifically refers to the clash that occurs when two distinct cultures come into contact, leading to the imposition of one culture's norms and values over the other. In this scenario, the replacement of Native American norms by those of English settlers exemplifies primary culture conflict because it highlights a foundational change in values and beliefs where the dominant group (English settlers) supersedes the native culture of the Indigenous population.

This stands in contrast to secondary culture conflict, which may involve differences within a single, more mixed culture, often revolving around specific societal norms versus criminal law, rather than an overt clash of distinct cultural groups. Legal assimilation and normative adaptation also focus on the processes of integrating norms and values but do not capture the same dynamic of primary cultural clash that Sellin discussed in relation to different and conflicting cultural systems. This context makes the identification of the situation as a primary culture conflict particularly fitting in the examination of how settler norms replaced those of Native Americans.
