Next month, America will celebrate its Semiquincentennial and this year’s Fourth of July is set to be the grandest one yet. The festivities will include the grand opening of the Theodore Roosevelt Presidential Library in Medora, North Dakota, alongside further national celebrations such as street block parties and fireworks happening over the three-day weekend.
So, what does 250 years of America look like? From the signing of the Declaration of Independence in 1776, the Statue of Liberty being shipped to New York Harbour in 1886 to the first humans landing on the moon in Apollo 11’s mission in 1969 — these are some of the defining moments in America’s history.
With that in mind, let’s have a look at five key topics that have made America into what it is today and remind ourselves of the people who have put the American spirit first, using images from our newly curated lightboxes 250 years of America – 21st Century and 250 years of America – Archive.

Landmarks
America has a wealth of well-known and much-loved landmarks which are must-see destinations for travellers across the globe. Whether natural or man-made, each site tells a unique story and holds symbolic meaning to America. As a nation, they take great pride in their landmarks; for instance, in 1872, President Ulysses S. Grant signed The Yellowstone National Park Protection Act, establishing Yellowstone as America’s first national park to be preserved for future generations.
Many 20th-century landmarks, such as the Golden Gate Bridge and the Lincoln Memorial, remain used and visited by millions today.
Activism
Throughout America’s history, there have been crucial progressive moments led by activists who have achieved major social and legal changes in America’s national system. One of the most impactful movements in its history was the Civil Rights Movement (1954–1968), which was led by Martin Luther King and famously drew in over 250,000 participants to the March on Washington in 1963.
Activism remains a powerful force today, with movements such as Black Lives Matter and No Kings generating momentum on the streets and on social media.
Space
Remaining the global leader in space technology in 2026 and following 165 space launches in 2025, America has made tremendous technological advancements in this sector within a brief period of time. Reflecting on its history, it was only 57 years ago that America successfully sent the first humans to the moon, which became a memorable moment witnessed by millions worldwide and continues to leave a lasting impact on American culture.
Missions such as Artemis II have kept the momentum going by successfully sending astronauts around the moon this year for the first time in over 50 years.
Annual Festivities
Rooted in the fabric of American society are several annual festivities, such as Halloween, St Patrick’s Day, and Thanksgiving which bring communities together. In 1863, President Abraham Lincoln proclaimed the last Thursday in November as the national holiday Thanksgiving; at the time, this was to promote unity during the Civil War. It was later solidified by President Franklin D. Roosevelt in 1941, making the fourth Thursday in November the national holiday to lengthen the holiday shopping season.
There is no slowing down of these annual celebrations, as each year they continue to grow.
Pop Culture
Throughout the 20th century, American pop culture has shaped both the nation and the global entertainment industry. During the American Boom, an estimated 50 million people attended the movies weekly, which created household names such as Charlie Chaplin and Clara Bow. Pop culture has not only influenced the entertainment industry, but we’ve also seen the nation come together in counterculture movements, such as the 1969 Woodstock festival, which emerged as a response to the Vietnam War.
Over 460,000 attendees gathered at the three-day event to celebrate peace and music, with performances from legendary artists such as Jimi Hendrix, Janis Joplin and The Who. In today’s pop culture, we continue to see these historical influences in modern festivals such as Coachella.
