The country has done this twice before. In 1876, the Centennial Exhibition drew ten million visitors to Philadelphia, roughly one in five Americans alive at the time, and a Western Union operator at the fair received the news from the Little Bighorn on July 6, two days after the Fourth of July festivities on the grounds.
In 1976, the Bicentennial produced tall ships in New York Harbor, a dual-dated quarter still turning up in change fifty years later, and a commission Congress had to dissolve and replace halfway through the planning.
The next one is already underway.
What the Semiquincentennial Is
July 4, 2026, marks two hundred and fifty years since the Continental Congress adopted the Declaration of Independence. The official term is the Semiquincentennial — semi for half, quin for five, centennial for hundred — though the U.S. Semiquincentennial Commission has spent the better part of a decade trying to get “America250” to stick instead. Both terms are correct. One fits on a banner.
Congress established the Commission in 2016 under Public Law 114-196. It is a federal body, but it does not run the anniversary the way a single agency runs a parade. It coordinates. The actual programming with exhibitions, reenactments, education initiatives, and ceremonies happens at the state and local level. All fifty states have their own commissions, as do the territories and the District of Columbia. Most counties have one too.
In practical terms, the anniversary is a multi-year observance rather than a single day. The arc began in 2025 and runs through at least 2027, covering the path from the Declaration to the ratification of the Constitution in 1788 and the Bill of Rights in 1791.
If the Bicentennial was a year, the Semiquincentennial is closer to a decade.
The Dates That Anchor It
A handful of dates serve as the structural spine of the observance.
April 19, 2025 marked two hundred and fifty years since Lexington and Concord. Reenactors on Battle Road drew crowds large enough that the National Park Service closed parking by sunrise.
June 14, 2025 was the U.S. Army’s 250th birthday. The Army was established by the Second Continental Congress on June 14, 1775, nineteen days before George Washington took command of the Continental forces at Cambridge. June 14 is also Flag Day, by act of Congress in 1949.
October 13, 2025 was the Navy’s 250th. November 10, 2025 was the Marine Corps’. Each service observes its founding differently, but 2025 was the first year since 1775 in which all three branches could claim the same quarter-millennium.
July 4, 2026 is the keystone date. Philadelphia will anchor the national programming, with ceremonies at Independence Hall, the Liberty Bell, and the surrounding historic district. Boston, the original thirteen states, and Washington, D.C. will carry parallel events. Because the Fourth falls on a Saturday, most local communities will program across the whole weekend.
The calendar does not stop there. 2027 covers the Articles of Confederation and the earliest state constitutions. 2028 reaches the Constitutional Convention, two hundred and fifty years after delegates gathered in Philadelphia for a second time. 2031 brings Yorktown’s 250th. 2041 brings the Bill of Rights.
What 1876 Looked Like
The Centennial Exhibition opened on May 10, 1876, on 285 acres in Fairmount Park, Philadelphia. It was the first official World’s Fair held in the United States. Ten million visitors passed through the gates between May and November, a figure equal to roughly one in five Americans at the time.
President Ulysses S. Grant opened the Exhibition alongside Dom Pedro II of Brazil. The right arm and torch of the Statue of Liberty stood on the grounds, raising funds for the pedestal that would not be finished for another decade. Alexander Graham Bell demonstrated the telephone in one hall. H.J. Heinz debuted tomato ketchup in another.
The official flag that summer had thirty-seven stars. Colorado was admitted to the Union on August 1, 1876, earning it the nickname “the Centennial State.” The thirty-eight-star pattern would not become official until July 4, 1877, but a great many thirty-eight-star flags flew anyway, stitched by manufacturers and households eager to be ahead of the change.
The Centennial was not quite the triumphant tableau its catalogs described. News of the Battle of the Little Bighorn, fought June 25 and 26, reached Philadelphia by telegraph on July 6, two days after the Fourth of July festivities on the grounds. Custer and most of the detachment he led were killed.
Reconstruction was collapsing in the South. The Hayes-Tilden presidential election that November would remain the most disputed in American history until 2000. The Exhibition ran until November anyway. Both things are true.
What 1976 Looked Like
The Bicentennial was organized by two bodies in sequence. Congress established the American Revolution Bicentennial Commission in 1966. By 1973, after years of criticism over commercialization and internal dysfunction, Congress dissolved the Commission and created the American Revolution Bicentennial Administration to finish the job. The Administration’s charter expired on June 30, 1977, and its records were transferred to the National Archives.
What the Bicentennial produced, despite its planning troubles, became the memory most living Americans still have of a major anniversary.
Operation Sail 1976 brought sixteen Class A tall ships and dozens of smaller vessels to New York Harbor on July 4. An estimated six million spectators watched from shore.
The American Freedom Train, a twenty-six-car traveling exhibition, toured forty-eight states between April 1975 and December 1976. It carried original copies of the Declaration, the Constitution, and the Bill of Rights, along with several hundred other artifacts.
The U.S. Mint issued bicentennial coinage that year, including a dual-dated quarter, half dollar, and dollar, each dated 1776–1976. Many still turn up in pocket change today. The Postal Service issued more than one hundred commemorative stamps across the observance.
The fifty-star flag flew, unchanged from its adoption on July 4, 1960 after Hawaii’s admission. Commemorative patterns with thirteen stars, thirteen stripes, and the various Revolutionary War battle flags appeared on porches and in parades across the country, most of them manufactured in the two years leading up to the anniversary.
The Bicentennial was also contested. The People’s Bicentennial Commission, founded in 1971 by Jeremy Rifkin as a counter-organization, argued that the corporate sponsorship of the official observance obscured the Revolution’s radicalism. Protests occurred at several events, including the July 4 gathering at the Old North Church in Boston.
Neither the scale of the protests nor that of the celebrations is well remembered today. That is how most anniversaries eventually settle, into a version clean enough to print.
What Flags to Fly and When
The Flag Code (4 U.S.C. §§ 1–10) does not prohibit the display of historical American flags. It requires only that when any other flag is flown with the current national flag, the current flag takes precedence. That means flown higher on the same pole, or at the same height on a separate pole of equal prominence.
For the Semiquincentennial arc, several historical patterns suit the specific milestones being observed.
The Grand Union flag, sometimes called the Continental Colors, was raised by George Washington on Prospect Hill in Cambridge, Massachusetts, on January 1, 1776. Thirteen red and white stripes, with the British Union Jack in the canton. It was the first flag flown over the Continental Army. It is appropriate for observances tied to the early Revolution, including Lexington and Concord anniversaries, the Army’s birthday, and the siege of Boston.
The thirteen-star Betsy Ross flag, with its ring of thirteen stars, is the best-known pattern from the Flag Resolution of June 14, 1777. The circle-of-stars arrangement is one of several that appeared in that era. Whether Ross herself produced the first one has been a subject of debate among historians since her grandson first made the claim in 1870. The pattern is real. The attribution is contested. It is appropriate for July 4 observances throughout the Semiquincentennial period.
The Bennington flag, with a large “76” in the canton and an arch of stars above, is traditionally associated with the Battle of Bennington on August 16, 1777. The surviving example at the Bennington Museum likely postdates the battle. Textile analysis suggests an early nineteenth-century manufacture. The pattern is nonetheless strongly associated with the Revolutionary War era and is particularly suitable for 2027 observances.
The current fifty-star flag is the flag for all general civic observance. A good outdoor residential flag is three by five feet, with embroidered stars on sewn stripes and solid brass grommets on a canvas heading. It will last two to three years of daily use before the fly end begins to fray.
A commercial installation on a thirty- or forty-foot pole will wear faster. Most businesses replace theirs annually. Nylon handles wind well and dries quickly. Polyester lasts longer but flies heavier and is better suited to larger poles or higher-wind locations.
For Memorial Day during the Semiquincentennial, the flag is flown at half-staff from sunrise until noon, then raised briskly to full-staff for the remainder of the day. This is standing protocol, not a Semiquincentennial adjustment.
What to Watch For
The twelve months ahead contain the densest programming of the entire observance.
June 14, 2026, is Flag Day and the Army’s 251st birthday. It’s the first Flag Day since the service branch 250ths concluded.
July 4, 2026, is the keystone. Philadelphia, Boston, and the state capitals of the original thirteen will carry the largest programming. Most local communities will anchor on the Fourth or the weekend after.
September 17, 2026, is Constitution Day. Not a Semiquincentennial milestone by itself, but the observance grows in weight as the calendar moves toward the Constitution’s 250th in 2037.
October 19, 2026, marks the 245th anniversary of Cornwallis’s surrender at Yorktown. Several state commissions are beginning to program the Yorktown arc in anticipation of its 250th in 2031.
Beyond 2026, the observance continues. The Treaty of Paris in 1783. The Constitutional Convention in 1787. The Bill of Rights in 1791. The country has been here before, and it will be here again. The record of the last two attempts is available to anyone willing to read it. What worked. What did the commissions get right and wrong.
The country has done this twice before. It’s worth doing well.
