Frederick Lewis Allen, Harper & Brothers, 1931.
Thesis Statement
Frederick Lewis Allen’s Only Yesterday argues that the 1920s constituted a decisive rupture in American life—a decade in which the swift forces of mass consumerism, urbanization, new media, and sexual liberation permanently displaced the Victorian moral order that had governed the nineteenth century—and that this cultural revolution, proceeding under a veneer of political conservatism, laid the emotional and social groundwork for both the Crash of 1929 and the Great Depression that followed.
Summary
Written barely a year after the stock market collapse, Only Yesterday remains one of the most influential works of popular history ever published in the United States. Allen, an editor at Harper’s Magazine, set out not to write a conventional political chronicle but to capture “the feel” of the decade as ordinary Americans experienced it. The book proceeds thematically rather than strictly chronologically, weaving together politics, crime, fashion, literature, religion, finance, and sports into a single narrative fabric.
Allen opens with the immediate aftermath of World War I, describing the “return to normalcy” under Warren G. Harding—a mood he treats less as a policy program than as a national psychological state. He then pivots to the great social upheavals that defined the era: the Red Scare and Palmer Raids, the rise of Prohibition and the speakeasy culture that defied it, and the emergence of the “flapper” as a symbol of generational revolt against Victorian restraint. His chapters on the Scopes Trial and the resurgence of the Ku Klux Klan reveal how profoundly the decade’s modernity unsettled traditionalist America.
The heart of the book lies in its analysis of the bull market of the late 1920s. Allen’s celebrated account of the speculative mania—the proliferation of brokerage offices, the “margin” buying that allowed ordinary citizens to gamble on stocks they could not afford—is unlike any financial journalism that preceded it. He treats the market not as an abstraction but as a mass emotional phenomenon, a great national confidence game whose inevitable collapse he narrates with an almost tragic cadence in the famous closing chapters.
As a work of synthesis, Only Yesterday is less a work of archival scholarship than of journalistic recollection, but its immediacy is its greatest strength. Allen wrote as a contemporary observer with access to the full documentary record of the decade’s press and popular culture. The book established a template for narrative social history that has influenced countless later historians, from William Manchester to David Halberstam. Its enduring value lies in its insistence that culture—the way people dressed, spoke, spent money, and conducted their private lives—is as historically significant as legislation or diplomacy.
Chapter-by-Chapter Breakdown
Prelude: May 1919
Allen establishes the postwar mood through a vivid recreation of a single month, introducing the upheavals—labor strikes, race riots, the Boston police strike—that would set the tone for the decade.
Chapter I: The Big Red Scare
Examines the anti-Bolshevik hysteria of 1919-1920, detailing Attorney General A. Mitchell Palmer’s raids and the broader assault on civil liberties in the name of national security.
Chapter II: The Revolution in Manners and Morals
Analyzes the transformation of sexual behavior, women’s fashion, and courtship practices, including the influence of Sigmund Freud (as popularly misunderstood), the automobile, and the movies.

Reviews the presidency of Warren G. Harding, the Teapot Dome affair, and the contrast between the administration’s oil-tainted corruption and the public’s indifference to it.
Chapter IV: Coolidge Prosperity
Examines Calvin Coolidge’s presidency and the era’s prevailing faith in business as the national religion.
Chapter V: The Side of the Angels
Treats the Scopes “monkey trial” in Dayton, Tennessee, as a symbolic confrontation between fundamentalist rural America and urban modernity, with William Jennings Bryan and Clarence Darrow as its dueling champions.

Returns to social mores, focusing on the further loosening of sexual codes and the emergence of the “new” woman in the latter half of the decade.
Chapter X: The Tyranny of Things
Analyzes the rapid diffusion of consumer goods—radios, automobiles, household appliances—and the new culture of installment buying and advertising that emerged to sustain mass consumption.
Chapter XI: The Last Stand of the Old Order
Addresses the 1928 presidential election, the anti-Catholic campaign against Al Smith, and the victory of Herbert Hoover.
Chapter XII: The Crash
Recounts the speculative climax of 1928-1929, the October market collapse, and the immediate aftermath, with a devastating portrait of a financial system built on collective delusion.
Chapter XIII: Aftermath, 1930
A brief epilogue describes the onset of the Depression, the erosion of confidence, and the close of the American decade.
Scholarly Reception
When Only Yesterday appeared in December 1931, reviewers greeted it as a revelation. The New York Times called it “a brilliant book” that had captured the decade’s essence better than any previous attempt. Charles A. Beard, then the nation’s most prominent historian, praised Allen’s ability to see “the significance of the trivial” and recommended the book to readers who wanted to understand how the prosperity of the 1920s had given way to depression. Over time, the book acquired canonical status. It never left print, and subsequent historians—even when questioning its interpretations—have treated it as the essential starting point for understanding the era’s popular culture.
Later scholars have criticized aspects of Allen’s account. His treatment of African American history in the decade is almost wholly absent, despite the Harlem Renaissance and the Great Migration receiving major attention in more recent historiography. His focus on the white middle class renders the experiences of working-class ethnic communities largely invisible. His suggestion that the decade’s moral revolution constituted a “permanent” change has also been complicated by the more conservative 1950s. Yet the book’s core framework—that the 1920s marked the birth of modern consumer America—has proven durable. William E. Leuchtenburg, the leading New Deal historian, acknowledged that Allen’s account of the lead-up to the Crash remains unsurpassed for its narrative power.
Representative quotes:
“The prosperity of the twenties was not built upon solid foundations; it was a structure of sand, resting upon the unbridled optimism of the American people and the willingness of the wise and the foolish alike to gamble in the stock market.”
“Never in history had a people been so variously and so relentlessly entertained, and never had a people so much needed to be entertained; for the strain of the new era of hurry and noise and excitement was telling upon them. They were like the patient in the old joke who, when told that his arm was broken, replied, ‘It doesn’t hurt at all.’ ‘No,’ said the doctor, ‘it is a very bad break indeed.'”
For a modern audience, Allen’s book offers more than nostalgia. It provides a chilling reminder that financial euphoria is not a permanent condition of human nature but an episodic one—and that when it breaks, the consequences can be catastrophic. The book’s continuing popularity a century after the events it describes is testimony to its enduring insight: that the past, even at its strangest, helps illuminate the present.
