The idea of “two Americas,” or “red” and “blue” states, now dominates public discussion. “Political polarization,” the Pew Research Center reports, “is a defining feature of American politics today.”
But the idea that America is politically polarized isn’t new.
Last week marked the 160th anniversary of Abraham Lincoln’s “House Divided” speech, one of the most important addresses in U.S. history. Lincoln delivered it on June 16, 1858, to accept the Illinois Republican nomination for Senate. The speech marked his entrance into national politics at a time when the nation was profoundly at odds over slavery.
On the occasion of its 160th anniversary, Lincoln’s speech offers timely lessons about the costs of deep-seated political polarization.
My research examines how communities remember – and sometimes fail to remember – the lessons of the past.1  Lincoln’s description of the Union as a house divided is well-remembered today. But many Americans fail to heed its deeper lessons about equality and the moral foundations of popular government.

The Divided States of America

To cite the language of journalist Bill Bishop’s best-seller, The Big Sort,2  Americans have sorted themselves into distinct, homogeneous groups.
Complex social, moral, legal, and even scientific questions are now filtered through the lens of opposing party identifications. Political scientists Daniel Hopkins and John Sides conclude that U.S. “polarization has deep structural and historical roots” with “no easy solutions.”3 
In his “House Divided” speech, Lincoln addressed a nation even more fiercely divided by partisan acrimony, regional differences, and economic tensions than the United States of today.
Lincoln began his speech by attempting to predict whether a calamity was coming and if it could be prevented:
If we could first know where we are, and whither we are tending, we could then better judge what to do, and how to do it … I believe this government cannot endure, permanently half slave and half free.
The alternative to bitter polarization that Lincoln offered didn’t prevent the Civil War. But it shaped postwar understanding of the territorial, political, and even armed conflicts that led to it, and the lessons to be learned from it.

Union First

Above all, Lincoln stressed in his speech that “a crisis” over slavery was imminent. He asked Americans to choose the common purpose that would best serve their Union – a government of all free or all slave states – before the crisis chose for them.
Lincoln developed the idea that the Union is exceptional in public statements from 1858 until the end of the Civil War. In his First Inaugural Address (1861), Lincoln called the Union “perpetual,” and “much older than the Constitution … [N]o State upon its own mere motion can lawfully get out of the Union.” For years, Lincoln held that Americans belong to the Union before they belong to political parties.
His reasoning purposefully echoed George Washington’s Farewell Address (1796), which warned Americans that “the spirit of party” is a prime threat to “Union … a main prop of your liberty.” For Lincoln, Americans’ common identification with the guiding ideal of equality should transcend their affiliations with political parties.
Consider the symbolism of Lincoln’s main metaphor, the Union as a house:
A house divided against itself cannot stand …
I do not expect the Union to be dissolved – I do not expect the house to fall – but I do expect it will cease to be divided.
Building and maintaining a house is familial and collaborative. Family conflicts are inevitable; households fall apart if families don’t resolve those conflicts.
The metaphor of a house emphasizes interdependence, cooperation, and shared purpose. It asks how citizens might build and maintain something together, despite natural differences, rather than live and work separately.
These ideas have been lost in today’s social and political debates, which are dominated by competing party agendas and talk of irreconcilable “red” and “blue” state mentalities.
Lincoln’s central warning – “A house divided against itself cannot stand” – was rich in moral significance. A house should rest on a firm physical foundation for the safety of the family who lives in it. The Union, Lincoln implied, should rest on a firm moral foundation: a bedrock dedication to equality.
The Union, he believed, cannot be a compact of convenience or a loose-knit confederation. It was founded for a clear moral purpose: to extend conditions of equality to as many people as possible. The “new nation” that “our fathers brought forth” in 1776, Lincoln would say most memorably in his 1863 Gettysburg Address, was “dedicated to the proposition that all men are created equal.” Commitment to the principle of equality was an essential, not optional, basis of membership within.

Beware false prophets

Bipartisan compromise sounds good – but it can erode fundamental commitments to equality. By 1858, the United States had witnessed decades’ worth of political compromises over slavery: the Missouri Compromise of 1820, the Compromise of 1850, and the Kansas-Nebraska Act of 1854. All of these measures maintained the institution of slavery while purporting to limit it.
In his “House Divided” speech, Lincoln contended that such compromises only led to more intense conflict:
We are now far into the fifth year, since a policy was initiated, with the avowed object, and confident promise, of putting an end to slavery agitation. Under the operation of that policy, that agitation has not only, not ceased, but has constantly augmented.
Lincoln warned of false political prophets who earned praise for short-term bipartisan compromises without taking a firm stand on fundamental forms of inequality. They aimed, he said, to build a “political dynasty,” not a strong union:
Our cause, then, must be intrusted to, and conducted by its own undoubted friends – those whose hands are free, whose hearts are in the work – who do care for the result.
Lincoln’s opponent in the Senate campaign, incumbent Democratic Sen. Stephen A. Douglas, claimed to not care whether territories voted to become free or slave states, so long as the elections reflected the popular will in those territories. The “machinery” of such compromises over principles of equality, Lincoln said, would construct only “temporary scaffolding,” hastily fabricated to win elections before being “kicked to the winds.”

Equality over polarization

On its 160th anniversary, I believe Lincoln’s “House Divided” speech offers ways to imagine the nation other than as a patchwork of “red” and “blue” states.
Americans belong to a union first, parties second. Party machinery and false political prophets divide the house of the people; the people have the power to stabilize that house if they choose to do so. The union was founded on a dedication to equality. It retains a firm moral foundation by preserving commitments to principles of equality over region or party.
The primary offense against the principle of equality in Lincoln’s time was slavery. But Americans can apply the logic of his argument to contemporary inequities based on race, employment, gender, voting rights, criminal justice, religion, and more. The nation is a house divided, many times over, in all of those cases.
Lincoln didn’t claim that perfect equality could be achieved. But he saw broad commitments to the idea of equality as essential to the ongoing work of creating, as the Constitution puts it, a more perfect union – and a freer one for all.
The union must “become all one thing, or all the other” in order to be truly free. On this guiding principle, Lincoln declared, there can be no partisan dispute and no bipartisan compromise.
