Simple Definition:

Nationalism is a belief or ideology that promotes the interests, culture, and identity of a particular nation. It emphasizes the importance of loyalty and devotion to one’s own nation, often leading to a sense of pride and unity amongst its citizens. Nationalism can manifest in various ways, such as through patriotism [expressing love and support for your country], advocacy [political support] for self-determination, or the preservation of traditional values and customs.

For example, when people proudly display their country’s flag or support their national sports team, it reflects their nationalism. Nationalism can also be seen in the efforts of a nation to preserve its language, history, and traditions, or in the aspiration for independence by a group seeking to establish its own nation.
