The USA celebrates its 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.

he 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.

The plans for the Bicentennial began when Congress created the American Revolution Bicentennial Commission on July 4, 1966. Initially, the Bicentennial celebration was planned as a single city exposition that would be staged in either Philadelphia or Boston. After 6½ years of tumultuous debate, the Commission recommended that there should not be a single event, and Congress dissolved it on December 11, 1973, and created the American Revolution Bicentennial Administration, which was charged with encouraging and coordinating locally sponsored events. David Ryan, a professor at University College Cork, notes that the Bicentennial was celebrated only a year after the humiliating withdrawal from Vietnam in 1975 and that the Ford administration stressed the themes of renewal and rebirth based on a restoration of traditional values, giving a nostalgic and exclusive reading of the American past.
On December 31, 1975, the eve of the Bicentennial Year, President Gerald Ford recorded a statement to address the American people by means of radio and television broadcasts. Presidential Proclamation 4411 was signed as an affirmation to the Founding Fathers of the United States principles of dignity, equality, government by representation, and liberty.
