Why the Constitution calls America "a more perfect Union"

If something is perfect, how can it become more perfect?

It's a question many people have asked about one of the Constitution's most recognizable phrases: "to form a more perfect Union." As the United States prepares to celebrate its 250th anniversary, those four words offer an opportunity to revisit not only what the Founders wrote, but what they intended.

Creighton historians Simon Appleford, PhD, associate professor of history and director of the Digital Humanities Initiative, and Betsy Elliott-Meisel, PhD, professor of history, recently reflected on the meaning behind the phrase and why it continues to resonate nearly 250 years after it was written.

Far from claiming the new nation was perfect, the phrase reflected a different idea altogether. The Constitution established a framework built on the belief that the United States would continue to grow, adapt and improve over time. It recognized that no generation could anticipate every challenge the future would bring, leaving room for both the country and its governing document to evolve.

As Americans reflect on 250 years of history, the phrase "a more perfect Union" remains as relevant today as it was in 1787—not because it describes a finished nation, but because it recognizes that the work of building one is never complete.

A response to an imperfect beginning

To understand the phrase, it helps to understand the moment in which it was written.

Appleford explains that the Constitution was drafted in the aftermath of the Articles of Confederation, the nation's first governing framework, which exposed significant weaknesses in the young republic. The federal government had limited authority to collect taxes, regulate commerce or respond effectively to national challenges, making it difficult for the young nation to function as a unified country.

Rather than creating an entirely new vision for government, the Constitutional Convention sought to improve upon what had come before. The delegates recognized what wasn't working and set out to create a stronger system while preserving the balance between state and federal authority.

"The Founders never intended America to be perfect," Appleford says "They understood there was always room for improvement, and the systems they created reflect that."

Elliott-Meisel notes that this approach reflected broader Enlightenment ideals that emphasized reason, progress and thoughtful debate over rigid certainty. Instead of trying to create a government with all the answers, the Founders established a process that allowed the nation to continue improving over time.

One example of that philosophy is Article V of the Constitution, which establishes the amendment process. As Appleford explains, the Constitution intentionally gives future generations a constitutional path for change, allowing Americans to revise the nation's governing document as the country's needs evolve.

That process has been used 27 times since the Constitution was ratified. Amendments have abolished slavery, expanded voting rights, clarified presidential succession and addressed issues the Founders could never have anticipated. While intentionally difficult to amend, the Constitution was never intended to be unchangeable.

Progress through compromise

The idea of becoming "more perfect" did not end when the Constitution was signed. Throughout American history, moments of compromise and constitutional change have continued to reshape the nation.

Elliott-Meisel points to the Connecticut Compromise as one of the earliest examples. Faced with disagreement between large and small states over representation in Congress, delegates reached a solution that created the bicameral legislature still in place today: equal representation for every state in the Senate and representation based on population in the House.

The compromise demonstrated that disagreement did not have to prevent progress. Instead, competing interests could be reconciled through negotiation, creating a system that balanced conflicting priorities and allowed the new government to move forward.

Appleford highlights another milestone nearly a century later: the Reconstruction Amendments following the Civil War. Ratified after the Civil War, the 13th, 14th and 15th Amendments abolished slavery, established birthright citizenship and equal protection under the law, respectively, and expanded voting rights for formerly enslaved Americans.

Together, those amendments fundamentally reshaped the Constitution by expanding who it protected and moving the country closer to the ideals it set out to achieve. While the nation's pursuit of equality has continued, they remain one of the clearest examples of the Constitution's ability to evolve in response to the country's changing understanding of freedom and citizenship.

Though separated by decades, both moments illustrate the same principle: the Constitution was designed to allow the nation to address its shortcomings and continue moving forward.

Why it still matters

As the United States approaches its 250th birthday, "a more perfect Union" remains more than a historical phrase. It reflects an ongoing commitment to growth, recognizing that every generation has both the opportunity and the responsibility to strengthen the nation.

Elliott-Meisel says the anniversary provides an opportunity to reflect on the nation's continued pursuit of progress and the ideals that have shaped it from the beginning.

"The promise of America has always been that it will adapt and it will change," Appleford says. "The phrase 'a more perfect Union' suggests that we can always strive for better."

Ultimately, "a more perfect Union" was never a promise that the United States would become flawless. Instead, it expressed the belief that the nation would always have both the capacity and the responsibility to improve.

Conversations like this are central to the study of history at Creighton. Students are encouraged to examine historical events in context, wrestle with complex ideas and consider how the past continues to shape the present. Rather than viewing history as a collection of dates and facts, they learn to ask deeper questions about the people, ideas and decisions that continue to influence society today.

As America commemorates 250 years of independence, the Constitution's opening words remain a reminder that the nation's founders didn't expect perfection. They expected progress—and entrusted future generations with the responsibility to keep pursuing it.
