The term "nationalism" is generally used to describe two phenomena: (1)the members of a nation care about their national identity and(2) that the members of a nation seek to achieve (or sustain) self-determination.
It is traditional, therefore, to distinguish nations from states—whereas a nation often consists of an ethnic or cultural community, a state is a political entity with a high degree of sovereignty. While many states are nations in some sense, there are many nations which are not fully sovereign states. As an example, the Native American Iroquois constitute a nation but not a state, since they do not possess the requisite political authority over their internal or external affairs. If the members of the Iroquois nation were to strive to form a sovereign state in the effort to preserve their identity as a people, they would be exhibiting a state—focused nationalism.

A. political practice
B. race superiority
C. race identity
