If you’re gearing up for fireworks, barbecues, and patriotic playlists, here are 10 things you probably haven’t heard about the Fourth of July. The holiday marks the ratification of the Declaration of Independence on July 4, 1776, and every year the nation celebrates with parades, picnics, concerts, and plenty of red‑white‑blue fun.
10 Things You May Not Have Known About Independence Day
10 Not Every American Founding Father Approved the July 4 Date
During the Revolution, the Continental Congress actually voted for independence on July 2, 1776, when it passed a resolution separating the colonies from Great Britain. After that vote, the delegates turned their attention to the formal declaration, a document drafted by the Committee of Five—John Adams, Roger Sherman, Robert Livingston, Benjamin Franklin, and Thomas Jefferson. The drafting and subsequent revisions took a couple of days, so the final adoption of the Declaration didn’t occur until July 4.
Even though the resolution was approved on July 2, the public celebration settled on July 4 because that was the day the polished Declaration was officially adopted. John Adams, who later became the second president, argued that the true anniversary should be July 2, but his fellow delegates preferred the later date, and the nation has commemorated July 4 ever since.
9 There Were Only 2.5 Million People in the U.S. on July 4, 1776
When the Declaration was signed, the fledgling United States counted roughly 2.5 million souls. Fast‑forward to today, and the population has swelled to a staggering 334,995,511. To put that in perspective, between 1960 and 2021 the nation grew by 83.7 percent—an increase of about 151 million people over just 61 years, jumping from 180.67 million to 331.89 million.
This explosive growth was never accidental; early leaders envisioned a nation that would become a global beacon. By 2017, more than 50 million immigrants called America home, and the country’s influence spread from the historic roads of Rome to the bustling avenues of New York City.
8 It Took 94 Years to Make the Fourth a Federal Holiday
Believe it or not, the Fourth of July didn’t become an official federal holiday until 94 years after the Declaration’s adoption. The first public celebration took place in Philadelphia in 1777, featuring bonfires, ringing bells, and fireworks. The holiday’s popularity grew especially after the War of 1812, when patriotic fervor surged.
Congress finally formalized the day as a federal holiday in 1870, and it wasn’t until 1938 that the government upgraded it from an unpaid observance to a paid holiday for federal workers, cementing its status on the national calendar.
7 President Zachary Taylor Died After Falling Ill at a July 4 Celebration
Zachary Taylor, the 12th president of the United States, was a celebrated war hero from the Mexican‑American War before winning the 1848 election. On a sweltering July 4 in Washington, D.C., he attended the Independence Day festivities, indulging in a generous serving of cherries and iced milk, followed by a large glass of water back at the White House.
The combination of rich fruit, dairy, and the intense heat left him severely ill. Within four days he suffered cramping, diarrhea, nausea, and dehydration, ultimately succumbing on July 9, 1850.
6 America’s Founding Mother?
When British troops chased George Washington’s army out of New Jersey in December 1776, the Continental Congress hastily packed the Declaration of Independence into a wagon and fled Philadelphia for Baltimore. Weeks later, after the tide turned in favor of the colonists, Congress ordered a second printing of the document and, for the first time, included the signers’ names.
The task fell to Mary Katharine Goddard, a pioneering journalist and printer of the Revolutionary era. At a time when the British deemed the Declaration treasonous—punishable by death—Goddard boldly printed the document, risking her life.
She didn’t stop there; she also appended her own name to the printed copy, ensuring that beneath the signatures of the Founding Fathers sits the name of Mary Katharine Goddard, often celebrated today as America’s Founding Mother.
5 Not Everyone in America Was Free on July 4, 1776
While the birth of the nation was a cause for celebration, the reality was that many Americans remained enslaved. Slavery had been introduced to the colonies early on, and by 1776 it was legal across all thirteen colonies.
The institution persisted for nearly a century, eventually sparking the Civil War in 1861 when Southern states seceded to protect slave‑holding interests. After the Union’s victory, the 13th Amendment abolished slavery nationwide in 1865.
4 The Philippines Gained Independence from the U.S. on July 4
July 4 isn’t exclusive to the United States. The Philippines, after more than four decades under American rule, also celebrated its own independence on this date. The islands became a U.S. territory in 1898, transitioned to a Commonwealth in 1935, and endured Japanese occupation from 1941 to 1945 during World War II.
Following Japan’s defeat, the United States granted full sovereignty to the Philippines on July 4, 1946, establishing the Republic of the Philippines on the very day Americans were marking their own historic milestone.
3 Americans Consume 150 Million Hot Dogs on July 4
According to the National Sausage and Hot Dog Council, Americans are expected to devour roughly 150 million hot dogs during the Fourth of July weekend. A major driver of this appetite is Nathan’s Famous International Hot Dog Eating Contest, which takes place each July 4.
The contest’s origin traces back to Nathan Handwerker, who worked for Charles Feltman—often credited with popularizing the hot dog—in Coney Island. In 1916, Handwerker opened his own stand, selling hot dogs at half Feltman’s price. One July 4, he overheard a group of immigrants arguing over who was the most American. He challenged them to a hot‑dog‑eating showdown; an Irish immigrant named James Mullen won by devouring 13 hot dogs in 12 minutes, birthing the iconic contest.
2 Denmark Also Celebrates July 4
While American expatriates across Europe gather in bars and bases to mark the holiday, Denmark hosts one of the most notable foreign celebrations of Independence Day. The tradition dates back to 1912, when Danish immigrants in the United States encouraged their homeland to honor the U.S.’s openness to Danish newcomers.
Known as Rebildfesten, the festivities take place in Rebild National Park in northern Jutland. Starting as early as July 2 and culminating on July 4, the event features picnics, concerts, and fireworks, making it one of the largest Fourth of July celebrations outside the United States.
1 Three Presidents Died on July 4
In a striking historical coincidence, three U.S. presidents passed away on the Fourth of July. Thomas Jefferson and John Adams both died on July 4, 1826—the 50th anniversary of the Declaration of Independence—while James Monroe, the nation’s fifth president, died on July 4, 1831.
These deaths underscore a curious alignment of personal and national milestones, a rarity that has no parallel in American presidential history.
