American Renaissance (literature)
The American Renaissance period in American literature ran from about 1830 to around the Civil War. A central term in American studies, the American Renaissance was for a while considered synonymous with American Romanticism and was closely associated with Transcendentalism.
United States Bicentennial
The United States Bicentennial was a series of celebrations and observances during the mid-1970s that paid tribute to historical events leading up to the creation of the United States of America as an independent republic. It was a central event in the memory of the American Revolution. The Bicentennial culminated on Sunday, July 4, 1976, with the 200th anniversary of the adoption of the Declaration of Independence. 
The nation had always commemorated the Founding, as a gesture of patriotism and sometimes as an argument in political battles. Historian Jonathan Crider points out that in the 1850s, editors and orators both North and South claimed their region was the true custodian of the legacy of 1776, as they used the Revolution symbolically in their rhetoric.
