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.
Native American Renaissance
Although the primary use of the term has been literary, it has been used in a wider sense to describe "an increasing prosperity and sense of achievement among Indians [...] a widespread economic and cultural rebirth." For example, Joan Nagel applies the term to the totality of "the resurgence of American Indian ethnic identification and the renascence of tribal cultures during the 1970s and 1980s."
