As the nearly 12-minute film detailing its historical importance draws to a close, the tent that served as George Washington's home and headquarters during the American Revolution appeared in silhouette behind the screen. As the music swelled, the linen structure present at the birth of the nation was revealed.

It's an engrossing, dramatic moment, this reveal of the crown jewel in the collection of Philadelphia's new Museum of the American Revolution. The object of awe is a fragile, yellowing textile with scalloped trim, but oh, the stories it could tell.

The first museum devoted to the country's earliest years opens Wednesday, the anniversary of the opening battles of the American Revolution at Lexington and Concord and "the shot heard round the world" on April 19, 1775. It stands in "America's most historic square mile," a few blocks from the Liberty Bell, the first White House and Independence Hall, where the Declaration of Independence was signed and the U.S. Constitution ratified.

While there are dozens of museums and historical areas that touch on elements of the American Revolution, most focus on one battle or one person, Stephenson said. There's long been a need for a single museum that would offer a complete account of this crucial period, one that would not compete with the other sites but would fuel interest in the shared topic.

"As Benjamin Franklin said in 1776, 'We must all hang together or we will surely hang separately,'" Stephenson said. "It's a big global story, but Philadelphia is a place where all those threads cross."

While some may think that the success of Broadway's "Hamilton" was the driving force behind the museum, the show had its stage debut in 2015 and Stephenson has been involved in this project for more than 10 years. In fact, many of the core exhibition items come from the collection of the Rev. W. Herbert Burk, who began advocating for a museum to honor Washington in the early 1900s.

Still, "Hamilton" has been a gift to the museum, Stephenson said, noting how the fourth-graders who applauded Washington's tent also ran through the exhibition singing the show's songs and pointing out familiar faces and scenes. The museum's location, on the site of a former National Park Service building, is also fortuitous: across the street from the First Bank of the United States, which Hamilton founded, and a restaurant called the Little Lion, which was one of Hamilton's nicknames.

"It's prepared this huge audience to receive this museum when they would have been arriving cold and without points of reference," Stephenson said. "It acknowledges that there's complexity, that it's messy, that these were not demigods the likes of which we'll never see again. When you know the real story, you realize there are Alexander Hamiltons among us today."

Exhibition items include a Revolutionary War cannon, a pair of bootees made from the red jacket of a fallen British soldier for an American baby, and a mug from the 1770s that still smells of rum. After seeing a video re-creation of men pulling down a lead statue of King George III on horseback in New York in 1776, visitors can see large chunks of the statue that still exist and learn that the rest was transformed into 42,000 musket balls referred to as "melted majesty."

The museum encourages visitors to approach its exhibits with four questions in mind: How did people become revolutionaries? How did the revolution survive its darkest hours? How revolutionary was the war? What kind of nation did the revolution create?

The museum takes a thoughtful, yet playful approach. "More Empire, More Problems" reads the wall of a gallery that breaks down the challenges Britain faced managing its global empire. Touch-screen displays throughout allow visitors to ponder what choice they would have made on the eve of war.

Engravings are animated, including one from 1775 that shows fighting at Concord Bridge. The addition of movement and sound presents the picture in an entirely different light. Nearby are items that "were witnesses to the fight," Stephenson said, like a mirror from a farmhouse seen in the background and a piece of the bridge.

The museum wants to tell a deeper story, which means acknowledging that even heroes had flaws. Washington often shared his tent with an enslaved African who served as his valet. Native American tribes that chose to support Washington's Army did so believing that they would be well-treated in victory. Free Africans did the same with the same misperception.

The final display features a wall of photographs of people who were alive during the Revolutionary War. As visitors walk along taking in the photos, they draw closer to a wall of mirrors bearing the words "Meet the future of the American Revolution."
