Nationalism is a political, social, and economic system characterised by promoting the interests of a particular nation particularly with the aim of gaining and maintaining self-governance, or full sovereignty, over the group's homeland. The political ideology therefore 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. Nationalism therefore seeks to preserve the nation's culture. It often also involves a sense of pride in the nation's achievements, and is closely linked to the concept of patriotism. In some cases, nationalism referred to the belief that a nation should be able to control the government and all means of production.
