A national symbol is a symbol of any entity considering and manifesting itself to the world as a national community: the sovereign states but also nations and countries in a state of colonial or other dependence, federal integration, or even an ethnocultural community considered a 'nationality' despite having no political autonomy.
National symbols intend to unite people by creating visual, verbal, or iconic representations of the national people, values, goals, or history. These symbols are often rallied around as part of celebrations of patriotism or aspiring nationalism (such as independence, autonomy,or separation movements) and are designed to be inclusive and representative of all the people of the national community.
