American nationalism is a political and cultural ideology that emphasizes pride in the United States and its values, history, and achievements. It often promotes the idea of American exceptionalism, which suggests that the U.S. has a unique role in the world due to its democratic principles and diverse society. This form of nationalism can manifest in various ways, including patriotism, support for national sovereignty, and a focus on American identity. The movement can be seen in various historical contexts, such as during the American Revolution, the Civil War, and more recently in political discourse. American nationalism can also influence policies related to immigration, trade, and foreign relations, as it often prioritizes the interests of the nation over global considerations.
