Two divergent definitions have dominated sociologists' discussions of the nature of ethnicity. The first emphasizes the primordial² and unchanging character of ethnicity. In this view, people have an essential need for belonging that (5)  is satisfied by membership in groups based on shared ancestry³ and culture. A different conception of ethnicity de-emphasizes the cultural component⁴ and defines ethnic¹ groups as interest groups. In this view, ethnicity serves as a way of mobilizing a certain population behind issues (10) relating to its economic position. While both of these definitions are useful, neither fully⁵ captures the dynamic and changing aspects of ethnicity in the United States. Rather, ethnicity is more satisfactorily conceived of as a process in which preexisting communal⁶ bonds and common (15) cultural attributes are adapted for instrumental purposes according to changing real-life situations.

　　One example of this process is the rise of participation⁷ by Native American people in the broader United States political system since the Civil Rights movement of the (20)1960's. Besides leading Native Americans to participate more actively⁸ in politics (the number of Native American legislative⁹ officeholders more than doubled), this movement also evoked¹⁰ increased interest in tribal¹¹ history and traditional culture. Cultural and instrumental components¹² of (25 )ethnicity are not mutually exclusive, but rather reinforce one another.
