Nationalism is a complex, multidimensional concept involving a shared communal identification with one's nation. It holds that a nation should govern itself, free from unwanted outside interference, and is linked to the concept of self-determination. Nationalism is further oriented towards developing and maintaining a national identity based on shared characteristics such as culture, language, race, religion, political goals or a belief in a common ancestry. It often also involves a sense of pride in the nation's achievements, and is closely linked to the concept of patriotism.
