American Renaissance
The American Renaissance was a period of American architecture and the arts from 1876 to 1917, characterized by renewed national self-confidence and a feeling that the United States was the heir to Greek democracy, Roman law, and Renaissance humanism. The era spans the period between the Centennial Exposition (celebrating the 100th anniversary of the signing of the Declaration of Independence) and the United States' entry into World War I.
History of the United States (1789–1849)
Spurred on by the Second Great Awakening, Americans entered a period of rapid social change and experimentation. New social movements arose, as well as many new alternatives to traditional religious thought. This period of American history was marked by the destruction of some traditional roles of society and the erection of new social standards. One of the unique aspects of the Age of Reform was that it was heavily grounded in religion, in contrast to the anti-clericalism that characterized contemporary European reformers.
