Step-by-step explanation:
The late nineteenth century was known as the “Age of Imperialism,” a time when the United States and other major world powers rapidly expanded their territorial possessions.
The belief that the U.S. distinguishes from other nations because of its unique global mandate to promote liberty and democracy is partially embedded in American exceptionalism. This hypothesis always goes back to the words of Alexis de Tocqueville, a French analyst from 1800s who concluded that the United States is a special nation, "going on a path which is unlimited."
