Planning for the 1976 Bicentennial commemoration began under President Lyndon B. Johnson in 1966 with the establishment of the American Revolution Bicentennial Commission and was to be a World’s Fair modeled after the 1876 Centennial held in Philadelphia, Pennsylvania. The Fair was meant to celebrate Johnson's "Great Society" programs and look forward to other advancements in America's future. However, the plans changed after the election of President Richard Nixon in 1968. The American Revolutionary Bicentennial Administration was tasked with planning the celebrations, and faced criticism by people who felt it was overly politicized and did not represent most Americans. Planning for the Bicentennial was occurring at the same time as numerous sources of unrest continued across the country. This included the Vietnam War, the women's rights movement, the civil rights movement, the environmental rights movement, and, eventually, the Watergate scandal. As a result, in 1973, Congress replaced the original commission with the American Revolution Bicentennial Administration, who launched “Bicentennial Communities,” a project that supported and publicized local programming and community-based initiatives. These regional initiatives sparked interest in family and community histories and served the needs of local communities. There were around 66,000 events including picnics, presentations, parades and other celebrations across the country.
