nationalistic

Nationalism is an ideology or movement that holds that the nation should be congruent with the state. As a movement, it presupposes the existence and tends to promote the interests of a particular nation, especially with the aim of gaining and maintaining its sovereignty (self-determination) over its perceived homeland to create a nation-state. It holds that the nation should govern itself, free from outside interference (self-governance), that a nation is a natural and ideal basis for a polity, and that the nation is the only rightful source of political power. It further aims to build, and maintain, a single national identity, based on a combination of shared social characteristics such as culture, ethnicity, homeland, language, politics, religion, traditions, or belief in a shared singular history, and to promote national unity or solidarity. There are various definitions of a "nation", which leads to different types of nationalism. The two main divergent forms are ethnic nationalism and civic nationalism. Read more on Wikipedia
