Americans observed Memorial Day on Monday, May 25, 2026, against the backdrop of the U.S. war in Iran and elevated gasoline prices that the Associated Press reported could affect travel. The holiday, formally dedicated to mourning the nation’s fallen service members, has for generations also signaled the unofficial start of summer — a long weekend of barbecues, parades, and retail discounts, its origins stretching back to the bloodiest conflict in American history.
The holiday’s roots lie in the Civil War, which killed more than 600,000 Union and Confederate service members between 1861 and 1865. The first national observance of what was then called Decoration Day occurred on May 30, 1868, after an organization of Union veterans called for decorating war graves with blooming flowers. By then the practice was already widespread: Waterloo, New York, began a formal observance on May 5, 1866, and was later proclaimed the holiday’s birthplace, while Boalsburg, Pennsylvania, traced its first observance to October 1864, according to the Library of Congress. Women in some Confederate states also decorated graves before the war’s end.
David Blight, a Yale history professor, points to an even earlier commemoration in Charleston, South Carolina. On May 1, 1865, as many as 10,000 people, many of them newly freed Black Americans, held a parade, heard speeches, and dedicated the graves of Union dead who had perished in a Confederate prison. A total of 267 Union troops had been buried in a mass grave; after the war, members of Black churches interred them in individual graves. “What happened in Charleston does have the right to claim to be first, if that matters,” Blight told the AP in 2011.
The struggle over the holiday’s meaning began almost immediately. As early as 1869, The New York Times wrote that the holiday could become “sacrilegious” and no longer “sacred” if it focused more on pomp, dinners, and oratory. In an 1871 Decoration Day speech at Arlington National Cemetery, abolitionist Frederick Douglass warned that Americans were forgetting the war’s central cause. “We must never forget that the loyal soldiers who rest beneath this sod flung themselves between the nation and the nation’s destroyers,” Douglass said.
Those concerns proved well-founded, according to Ben Railton, a professor of English and American studies at Fitchburg State University in Massachusetts. Although roughly 180,000 Black men served in the Union Army, the holiday in many communities would essentially become “white Memorial Day,” especially after the rise of Jim Crow, Railton told the AP in 2023. Even in the 1880s, then-President Grover Cleveland was said to have spent the holiday fishing, and “people were appalled,” Matthew Dennis, an emeritus history professor at the University of Oregon, told the AP.
The 20th century reshaped the holiday further. The addition of Armistice Day — later Veterans Day — diluted Memorial Day’s singular focus on the Civil War dead, Dennis said. Then in 1971, Congress moved Memorial Day from its fixed May 30 date to the last Monday in May, creating a three-day weekend that Dennis said recognized the holiday’s transformation into a more generic remembrance of the dead as well as a day of leisure. A year later, Time magazine wrote that the holiday had become “a three-day nationwide hootenanny that seems to have lost much of its original purpose.”
The commercial and recreational dimensions were not purely modern inventions. Even in the 19th century, grave ceremonies were followed by picnics and foot races, Dennis noted. The holiday evolved alongside baseball, the automobile, the five-day work week, and summer vacation, according to the 2002 book “A History of Memorial Day: Unity, Discord and the Pursuit of Happiness.” By the mid-20th century, a small number of businesses began opening defiantly on the holiday, and once the date shifted to Monday, “the traditional barriers against doing business began to crumble,” authors Richard Harmond and Thomas Curran wrote. Today, Memorial Day sales and travel are deeply woven into the nation’s observance.
In 2026, those traditions continued amid new strains. The AP reported that the ongoing war in Iran and heightened gas prices were affecting travel plans, but families across the country still turned out for ceremonies, parades, and gatherings. The National Moment of Remembrance, established by Congress, urged all Americans to pause at 3 p.m. local time for a moment of silence. As the holiday passed its 158th year, it carried the accumulated weight of its history: a day that began with flowers on fresh graves, was shaped by Black Americans’ early tributes, and now endures as both a memorial and the gateway to summer.
