Nationalism is a concept that emerged during key historical events such as the French Revolution, European colonialism, and the establishment of the United States. It refers to the love and loyalty towards one's own country, as well as the desire for self-rule and independence. During the French Revolution, nationalism played a central role in the fight against monarchy and the establishment of a republican government. In the case of the United States, nationalism grew during the Revolutionary War and led to the formation of a political framework for the states and the nation. European colonialism also sparked nationalist movements in colonized countries, seeking to assert their own cultural identity and gain independence from Western control.
