What is nationalism and what events inspired Americans?

Nationalism is a political ideology that emphasizes the interests and culture of a particular nation, often promoting unity and pride among its citizens. In America, events such as the American Revolution, the War of 1812, and the Civil War inspired a sense of nationalism by fostering a collective identity and shared values. The success of the Revolution and the establishment of a democratic government reinforced the belief in American exceptionalism, while the Civil War highlighted the struggle to unify the nation under a common purpose. These events collectively shaped a distinct American identity rooted in freedom, independence, and unity.
