America's 250th birthday arrives under extreme heat and deep national pessimism

A quarter-millennium of growth

In the 250 years since declaring independence from Great Britain, the United States has grown from 13 colonies covering 430,000 square miles into a continental power spanning approximately 3.7 million square miles, an eightfold increase. Its population has risen from roughly four million in 1790 to 343 million by 2025, according to Census data cited by the BBC. Those early years were far from secure: the nation nearly doubled in size with the 1803 Louisiana Purchase, but the War of 1812 left its survival uncertain.

Anybody who was looking at the colonies trying to create this nation is saying, all we need to do is stay over here and wait till they tear themselves apart and go back and pick them up.

Colin Woodard, director of the Nationhood Lab at Salve Regina University, traces today's regional divisions to those founding fractures. He divides the country into distinct cultural identities rooted in early settlement patterns, from Puritan-influenced New England to Scots-Irish Appalachia, that continue to shape American politics.

Celebrations from coast to coast

Events of all kinds are planned across the country on Saturday. Hoover, Alabama, will serve free apple pie and ice cream while attempting a Guinness record for the most simultaneous Coke-can openings. Mount Morris, Illinois, is adding extra bouncy houses and expanding its annual fireworks finale. Los Angeles and Philadelphia will host concerts, while New York City and Washington will feature military jet flyovers and large fireworks displays.

In Washington DC, the White House's Freedom 250 commission has organized the Salute to America celebration at the Washington Monument grounds, beginning at 1:15 p.m. with military flyovers. The evening program, starting at 7 p.m., will include national speakers and the Joint Armed Forces Orchestra. President Trump is scheduled to deliver remarks at 9:45 p.m., followed by a fireworks show at 10:30 p.m. featuring 850,000 shells launched from 10 sites, including the Lincoln Memorial Reflecting Pool and barges on the Potomac River. The display will last between 35 and 40 minutes.

Two-fifty is a big number, so go big or go home.

Aanand Dadawala, 50, of Paramus, New Jersey, plans to serve Tex-Mex food and samosas to his family before lighting fireworks.

Heat disrupts the plans

An oppressive heat wave has already upended events that were years in the making. On Friday, Philadelphia organizers canceled what was shaping up to be one of the city's largest parades, with more than 50 marching bands and about 20 floats set to participate. The afternoon high was expected to reach 104 degrees Fahrenheit, with a heat index of 112. In Washington, the Great American State Fair, a 16-day event that opened on June 25, was temporarily closed on Friday afternoon as temperatures hit 100 degrees. Around 180 million people across the central and eastern United States were under extreme heat warnings or advisories on Friday.

Forecasters expect temperatures in New York, Washington, and Philadelphia to climb near 100 degrees again on Saturday. The National Independence Day Parade in Washington is still scheduled to begin at 10:30 a.m., and the state fair plans to reopen at 10 a.m.

An anxious milestone

The 250th anniversary arrives at a moment of deep national unease. A Pew Research Center poll found that 69 percent of Americans are dissatisfied with the country's direction, and 59 percent think the nation's best years have passed. According to The Economist, less than half of Americans say they are "very proud" to be American. Six in ten believe their country will be "less important in the world" by 2050, and just 17 percent are "almost certain" the United States will reach its 500th birthday.

The celebrations are also shadowed by political controversy. Several artists dropped out of state fair events, and some states declined to send representatives, citing expenses and, in one case, the event's partisan nature. Protesters under the "No Kings" slogan plan marches in multiple cities on July 4, denouncing what they call an excess of presidential power. The commemorations unfold against the backdrop of what the New York Times describes as a deeply unpopular war with Iran.

It doesn't really make a difference to me if it is 250. Happy birthday, America, I guess.

Arlene Lewis, a nursing student from Newark shopping for fireworks in Union, New Jersey, said the prices of gas and groceries were more front of mind than the milestone.

What lies ahead on July 4

Despite the heat and political tensions, Washington's security apparatus is fully mobilized. DC Mayor Muriel Bowser has led coordination meetings for what is expected to be one of the largest Independence Day gatherings in years. The operational plan covers the Capitol Hill and Palisades parades, National Mall activities, the state fair, the Washington Nationals game, and the fireworks show. Trump separately announced what he described as "the most spectacular Trump rally of all," to be held in Washington the same day, further polarizing an already charged commemoration.
