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.

The dominant social class of the Northeast possessed the confidence to proclaim an "American Renaissance", which could be identified in the rush of new public institutions that marked the period—hospitals, museums, colleges, opera houses, libraries, orchestras— and by the Beaux-Arts architectural idiom in which they splendidly stood forth, after Chicago hosted the World's Columbian Exposition of 1893.
