Jingoism is an extreme form of patriotism that often advocates for aggressive foreign policy and military action. This intense national pride can lead to a fervent belief in one's country's superiority and a desire to expand its influence or territory, often at the expense of others. In the context of the Spanish-American War, jingoism fueled public support for intervention in Cuba and the Philippines, as many Americans felt it was their duty to spread democracy and civilization, reflecting a mix of nationalism and imperialism.
