American exceptionalism refers to the opinion that the United States is qualitatively different from other nations. Its exceptionalism stems from its emergence from a revolution, becoming "the first new nation", and developing a unique American ideology, based on liberty, egalitarianism, individualism, populism and laissez-faire". This observation can be traced to Alexis de Tocqueville, the first writer to describe the United States as "exceptional". Although the term does not imply superiority, some writers have used it in that sense. To them, the United States is a "shining city on a hill", and exempt from historical forces that have affected other countries.
