What are three causes of the rise of radical nationalism

to promote peace

Explanation:

Nationalism holds that each nation should govern itself, free from outside interference, 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 shared social characteristics of culture, ethnicity, geographic location, language, politics, religion, traditions and belief in a shared singular history, and to promote national unity or solidarity.

The causes of nationalism are created by manipulating the past.

Explanation:

The nation can be one of the factors of nationalism. The glorification of one's own nation but in the context of minimizing others in almost all situations leads to nationalist attitudes. All other elements of nationalism are tied to the very term nation. Mythomania is also an element of nationalism. Many peoples from certain historical myths are linked to the nation, and thus certain nationalist attitudes are formed. Religion can be an element of nationalism as well. The far-right (in the political sense) has sometimes throughout history collaborated with religious institutions to spread nationalism among the people. Thus, nationalists often labeled others as "unclean" in a religious sense and often called for others' destruction. Finally, elements of nationalism can also be reflected through language, in a similar way to religion.
