America’s milestone anniversaries have long served as a point of reflection for generations on the nation’s history, values, and journey. From the Centennial in 1876 to the Bicentennial in 1976, celebrations have included parades, fireworks, and speeches, all honoring the Declaration of Independence and the founding of the country in 1776.
This year, as Americans commemorate the 250th anniversary on July 4, the festivities carry on with a Great American State Fair on the National Mall, a speech from President Donald Trump, military flyovers, performances by the U.S. military band, and an impressive fireworks display boasting over 850,000 fireworks.
Now, let’s take a look back at some of America’s grandest birthday celebrations.
1826: 50th Anniversary of America’s Founding
The first notable milestone for the nation came in 1826, marking 50 years since the Declaration of Independence. Across the country, communities organized celebrations. In Washington, D.C., leaders invited Thomas Jefferson and John Adams—the last surviving signers of the Declaration—to attend; both, unfortunately, declined due to health issues. Strangely, they both passed away on July 4, just hours apart.
This coincidence resonated with many Americans, deepening the significance of Independence Day. A memorial service for both leaders was held in D.C., and various commemorations helped solidify the tradition of celebrating the nation’s birthday.
1876: Centennial
In 1876, the United States celebrated its 100th anniversary with the Centennial Exposition in Philadelphia, the first official international world’s fair in the nation. The event showcased America’s industrial progress post-Civil War and introduced visitors to innovative technologies.
The six-month exposition, which drew nearly 10 million people globally, featured exhibits on art, culture, and technology. Attendees marveled at inventions like Alexander Graham Bell’s first telephone and Thomas Edison’s automatic telegraph machine; there was even a women’s pavilion highlighting achievements from the suffrage movement.
President Ulysses S. Grant even authorized the display of the original Declaration of Independence during this event, prompting subsequent preservation efforts for this vital document.
1926: 150th Anniversary of His Death
Fifty years later, another World’s Fair celebrated the 150th anniversary of the Declaration of Independence in Philadelphia. The 1926 Centennial International Exposition featured historical re-enactments and attractions commemorating the nation’s founding, including an impressive 80-foot replica of the Liberty Bell illuminated by thousands of light bulbs.
Yet, not every expectation was met—organizers anticipated around 30 million visitors, but only about 5 million paid admissions were recorded, leaving the exposition facing a significant debt.
1976: Bicentennial
The 200th anniversary took place during a time of recovery from the Vietnam War and the Watergate scandal. While Philadelphia initially aimed to host the Bicentennial World’s Fair, those plans fell through, but the celebration continued with national encouragement for local festivities.
In total, around 66,000 official events were organized across the country. Notable highlights include Operation Sail, which escorted over 200 tall ships into New York Harbor, and the American Freedom Train, which traveled across the U.S. carrying historical artifacts and documents.
