Historically Thinking

At his death on December 24, 1873, the Baltimore merchant Johns Hopkins left $7 million. which established both a hospital and the first American research university bearing his name. From its beginning Johns Hopkins pursued a distinctive and often eccentric course, moving from early dominance and innovation to decline and then renewal, all amidst recurring debates over what direction the university should take.

Those debates concerned questions that remain unsettled. Should a university emphasize advanced research or undergraduate education? Should research be pursued wherever an investigator’s curiosity leads, or directed toward practical ends? How much influence should do...

Since the invention of the printing press, printers have published books. And ever since books have been published, they have been sold. Yet today’s guest observes that, remarkably enough, there is a “paucity of literature on the history of the buying and selling of books.” While there have been plenty of studies of publishing and reading, “the commercial transactions that allowed books to pass from the producer to the reader are seldom explored.”

In his new book, The Bookshop: A History of Bookselling from the Dawn of Print to the Twenty-First Century, my guest Andrew Pett...

During the era of the American Revolution, food and drink had political meanings and could express what Americans thought their government should be. Protests over tea—and the brewing of tea alternatives—mammoth cheeses delivered to Thomas Jefferson and mammoth cakes baked for Election Day; from planting gardens to setting tables: all of these could be statements of political purpose. And these were activities and practices engaged in not only by white men with sufficient property to qualify them to vote, but by poor white men, women, enslaved people, and Native Americans. Thro...

The story of the Emperor Charles the Great, or Charlemagne, and his wider family is often told as one of glorious triumph followed by unfortunate decline. Emerging in more or less the 750s in what is now France, the Carolingians were part of a religious, political, social, and cultural order that was still haunted by the...

In September 1872, in the countryside north of Toronto, horses began to fall ill. Their noses ran, they coughed, and their breathing became “labored and severe.” In the worst cases, the sufferers could do nothing other than stand in their stalls “as if benumbed and paralyzed.” Eventually, an increasing number of them began to die.

Within days of the illness being identified, it was spreading throughout the new Canadian Confederation. By mid-October it had invaded New England and upstate New York; by late October it had nearly ended traffic on the Erie Canal. In early November it reach...

On December 16, 1944, as American troops retreated or fled before advancing German soldiers on the first day of what is now known as the Battle of the Bulge, Lieutenant Colonel Ray Love Trautman found himself leading an ad hoc formation of stragglers and stranded soldiers. This might not seem strange—that’s a lieutenant colonel’s job, isn’t it? But while Ray Trautman had the rank of a lieutenant colonel, his training was that of a librarian. He was, to be sure, the Army’s chief librarian, but that was hardly preparation for combat.

This is just on...

On July 18, 1863, the 54th Massachusetts—one of the first Black regiments in the Union Army, and the first raised in the North—led an assault on Fort Wagner, one of the fortifications defending Charleston, South Carolina.

Their attack was preceded by an eight-hour bombardment that did little damage to the fort’s walls or defenders. Moving through heavy Confederate small-arms fire, with their commander, Colonel Robert Gould Shaw, at their head, the 54th made their way up the walls and into hand-to-hand combat, but were bloodily repulsed. By the end of the action, Shaw and some 2...

On a winter morning in 1472, an investigator arrived at a poor widow’s home in the St. Nicholas district of the city of Dijon. He was there to interview a tenant, a pregnant woman named Jehanne, an immigrant from the county of Lorraine. She had reportedly been abducted and sexually assaulted by several men, and Jacques Borestal--the substitute prosecutor of Dijon–began his investigation by taking Jehanne’s testimony.

This was far from the fi...

Pericles of Athens was a complicated man, a man of twists and turns. Born into a lineage of Athenian aristocrats, he became a champion of democracy and indeed a masterful demagogue. A teenager by the end of the Persian Wars, he was one of the architects of an Athenian empire designed to ensure that Persia never again advanced westward. Possibly his earliest public act as an Athenian citizen was to sponsor four plays by Aeschylus, beginning a lifelong association with the artistic life of the city. And while he married as an Athenian aristocrat was expected to marry, his...

At the beginning of the twentieth century many thinkers, activists, and politicians would have been astonished if you told them that at the end of that century the nation-state would be the prevalent form of government throughout the world. After all, the previous fifty years had seen a revival of empires, and by 1900 everyone was living in a world of empires. The nation-state was not an obvious next step.

But following 1945, argues my guest Jon Wilson in his new book  Out of Chaos: How the Nation-State Emerged from the Ruins of World War II, the na...

Peter J. Ortiz was one of the most decorated United States Marines of the Second World War—and he served in the European Theater. In fact, his service was almost entirely within occupied France, where he worked for the Office of Strategic Services as the manager of a resistance network and later as the leader of a (sort of) Jedburgh Team. 

The stories of his exploits are legendary, though admittedly legendary among a much smaller circle of people than they deserve to be. One that can be verified is the time that, in a French bar...

Rage — Goddess, sing the rage of Peleus’ son Achilles,

murderous, doomed, that cost the Achaeans countless losses,

hurling down to the house of death so many sturdy souls,

great fighters’ souls, but made their bodies carrion feasts

for the dogs and birds,

and the will of Zeus was moving toward its end.

Begin, Muse, when the two first broke and clashed,

Agamemnon lord of men and brilliant Achilles.

Those were of course the opening lines of the Illiad, written by someone who we...

Even that overlooked yet essential little pinprick at the end of this sentence has a history. For once upon a time, there were no stops or periods. And therefore there were no sentences, at least as we conceive them now. “Changes in punctuation,” writes my guest Florence Hazrat, “like changes in language, are normal, but they’re also important reflections of our values.”

They are also, perhaps, indications of how we reframe the realities that we create with words. In her new book On the Mark: From Periods to Interrobangs, How Punctuation Changed the World, Hazrat rang...

YEAR of meteors! brooding year!

I would bind in words retrospective some of your deeds  

 and signs;

I would sing your contest for the 19th Presidentiad;.

I would sing how an old man, tall, with white hair,  

 mounted the scaffold in Virginia;

(I was at hand—silent I stood, with teeth shut close—I  

 watch'd;

I stood very near you, old man, when cool and indifferent, 

but trembling with age and your unheal'd  

 wounds, you mounted the scaffold;)

That was...

In early 1965, three executives boarded a plane in Japan, bound for the United States. “Unbeknownst to the U.S. Customs, they were carrying corporate secrets. Each man had carefully placed two vials of an isomerase enzyme into their pockets before the flight.” With it, they would change the world. For after two arduous years of nearly aerobic chemical engineering, their corporation produced what it called Isomerose 30. We know it, or its technically improved successors, as corn syrup.

That’s how my guest Brian Leech begins his intricate, multi-valenced history of what went on in Clinton, Iowa...

Most Americans remember the Louisiana Purchase as a remarkably good bargain: fifteen million dollars for an enormous tract of land that doubled the size of the United States. But that familiar cliché hides a large story. It covers over a lot of things, and suggests a few more that just aren’t so.

In his new book The Louisiana Purchase: The Grand Bargain and the Making of America, historian Alexander Mikaberidze places the Purchase within a global struggle involving France, Spain, Britain, Haiti, and the Caribbean. The transaction that reshaped the United States was not ine...

Running for about 177 miles along the Welsh-English border is the remains of an earthwork, a fortification over a hundred miles longer than Hadrian’s Wall. Built sometime in the eighth century, it is known as Offa’s Dyke, one of the few surviving reminder of one of the most formidable kings in English history.

“As a man,” writes my guest Roy Naismith, “Offa is effectively lost.” Winston Churchill framed the issue thus: “In studying Offa we are like geologists who instead of finding a fossil find only the hollow shape in which a creature of unusual streng...

"There was a time when the Declaration of Independence was news. Most books written about the Declaration have pursued questions about its precedence and authorship as well as its legacy. In 1776, when the Declaration was news, it was part of an ever-changing and circulating amalgam of accurate and inaccurate information, gossip, military intelligence, speculation, and opinion. At approximately one thousand three hundred and twenty words from ‘When in the Course of Human Events’ through ‘Our Sacred Honor,’ the Declaration took fewer than ten minutes to read and filled only one or two columns of a typical newspaper. This was a text t...

The Declaration of Independence has had two simultaneous lives. One is the life of its ideas, the life that scholars pay the most attention to: a life of fits and starts, surprisingly forgotten in the first years after the Revolution, then returning with a vengeance amid sectional conflict in the 1830s, during the Progressive Era, and again during the Civil Rights Movement.

Its second life is as a material document. It is an engrossed parchment rushed away from advancing British troops twice in its life, carried by carriage and train across the United States, tucked...

American independence was not simply the writing of the Declaration of Independence, nor even the vote that approved it. It was the culmination of decades of argument, persuasion, and political innovation. The American founding emerged through a succession of speeches, petitions, resolutions, constitutions, and other documents in which Americans struggled to define liberty, self-government, and the proper limits of power. And the conversation did not end there; it continued, and continues.

David Stewart explores that conversation in his new book, The Democracy We Must Keep: Seven Founders, Nine Documents, and the Ideas That Shaped Them. T...

On July 4, 1777, in Boston, the Reverend William Gordon gave one of the first July 4th orations in American history—certainly the first to become a pamphlet. For over a century these orations were a feature of the national festival, “an essential annual occasion for debating the present and future of American politics.” In the first century of American independence over one hundred thousand such speeches were delivered, about 2,500 of which survive in pamphlets. They were essential, until suddenly they were not.

How these orations surveyed the past and looked forward to the future is the focus...

The often extremely quotable Hannah Arendt once wrote that “the French Revolution, which ended in disaster, has made world history, while the American Revolution, so triumphantly successful, has remained an event of little more than local importance.”

My guest Richard Bell emphatically disagrees. In The American Revolution and the Fate of the World (Penguin, 2025), Bell argues that the Revolution was global from the very beginning. It drew participants from multiple continents, reshaped patterns of migration and trade, altered imperial policy from Canada to India, and inspired movements for liberty around the world. What Americans often rememb...

“This is a book about a cruel and ruthless war—a war without mercy—in which those caught up in it believed they had nothing to lose by fighting without regard for the rules of so-called ‘civilized warfare.’ It was the War for American Independence. At its grimmest level, this was a confrontation in which military restraint was more the exception than the rule, a struggle in which combatants believed their very existence was in question.”

Those are the words of my guest Mark Lender and his co-author, the late James Kirby Martin, from their book War Wit...

At his first inauguration, George Washington made a very carefully calibrated political statement: he wore a brown suit. It was tailored from a weave of superfine wool made in Hartford, Connecticut, and was so far from being the crude homespun which was for some an emblem of a proud American—or, for British cartoonists, of crude Brother Jonathan—that some newspapers criticized Washington for wearing a suit of imported fabric. The cloth seemed too good to have been made in America.

Washington wore two suits that day. In the evening, at the inaugural ball, he wore...

My guest Peter C. Mancall’s new book is Contested Continent: The Struggle for North America, c. 1000–1680. It is, now, the first volume in the Oxford History of the United States, an ongoing multi-volume narrative series—a series whose story is worth an episode in and of itself.

In Contested Continent, Mancall describes the foundation of that place which would eventually become the United States. It is a long era of human history which foreshadowed that which was to come, one in which peoples from four continents came together in a collision of violence and mutuality...

In the 1930s, five young men at Cambridge University became members of the Communist Party. This is not too surprising, in retrospect; many others were doing so as well. But these five men were recruited by the intelligence services of the Soviet Union, and for seventeen years they betrayed the secrets of Britain and the United States.

They are now often referred to as the Cambridge Five. They were Kim Philby, Donald Maclean, Guy Burgess, Anthony Blunt, and John Cairncross. While their story has been told and retold and retold in Britain, always as a...

“It was a cold January afternoon when I first came to the ghetto. I got there much later than I’d hoped. I’d spent much of the day elsewhere and had just lost track of time. It was already beginning to get dark. The campo seemed deserted. Shutters were closed, and apart from the tinkling of water in the wells, there was hardly a sound. There were no streetlights, barely even the glimmer of a lamp. But in the branches of the trees, thousands of tiny lights were shining.”

That is the opening paragraph of my gu...

The story of classical Greece is often told, rightly or wrongly, as the story of the alliance, competition, and eventual war between Athens and Sparta. Even in antiquity, each city fascinated the other. Athenians imagined Spartans as disciplined, laconic conquerors; Spartans regarded Athens with a mixture of admiration, suspicion, and alarm. Yet despite their differences, both cities shared fundamental Greek assumptions about honor, competition, citizenship, and excellence.

In his new book Athens and Sparta: The Rivalry That Shaped Ancient Greece , my guest Adrian Goldsworthy tells the story of classical Greece through the relationship between these tw...

On May 29, 1453, the city of Constantine—Constantinople—ceased to exist. For over a millennium it had stood as a center of Roman political power, Greek learning, and the Christian faith. Now its walls were breached, its emperor lay dead among the defenders, and its inhabitants were carried off into slavery.

Yet, as my guest Anthony Kaldellis argues, the city’s final resistance tells a different story from the one we often inherit. Its defenders did not regard their fate as inevitable. “Its fierce resistance at the end,” he writes, “stands as a final protest against narratives t...

For four years—from July 16, 1945, the date of the first atomic test, to August 29, 1949, when the Soviet Union detonated its first nuclear device—the history of nuclear weapons might appear to be an exclusively American story. But even that is misleading.

From the earliest theorization of the chain reaction, nuclear development was international: a web of scientific collaboration, technological transfer, espionage, and strategic imitation. As my guest David Holloway argues, nuclear weapons have always had an international history—one that can only be understood by examining not just individual states, but their relationships, perceptions, and intera...

At the very beginning of his forthcoming book Europe: A New History, my guest Roderick Beaton asks a simple but disarming set of questions: Why a “new” history of Europe? Why might we need one? And what makes this history new?

His answer is not merely about newly discovered facts, or even reinterpretations of old ones. It is about events. “To study history,” he writes, “is to look for patterns to make sense of the things that happen…When things change, when new and unexpected events suddenly reshape the world that we thought we knew around us, th...

“In the generation just before the Civil War, something like one-quarter of America’s enslaved people lived on large plantations with fifty or more forced laborers—in essence, work camps, where contact with whites might be limited and mostly utilitarian. Another quarter lived on plantations where twenty to fifty persons were held in slavery. The typical owner of, say, thirty captive Black workers knew his enslaved people individually, even if their true feelings often remained hidden from him.

That leaves half the South’s enslaved population living on properties where fewer than twenty Black people were hel...

“Over the course of the sixteenth century,” writes my guest Catherine Fletcher, “the handgun made a transition from a novel and decisive military technology to become an everyday object, in use across society and carrying a new set of cultural associations that would persist through the coming centuries.”

This was the firearm revolution.

In this conversation, Fletcher explores how an evolving technology became a transformative one—not simply changing warfare, but altering the structure of society itself. Guns moved from battlefields into cities, homes, and daily life. In doing so, they reshaped h...

The history of modern Syria is usually reduced to a story of autocracy, repression, and occasional revolt. And it is a short story, stretching back only to the fragmentation of the Ottoman Empire, or perhaps to the secret terms of the Sykes-Picot Agreement that divided the Near East between Britain and France. 

But my guest Daniel Neep has a different perspective. He believes that such narratives overlook “the pre-​colonial foundations for modern Syria that were undertaken by reformers, infrastructure builders and identity entrepreneurs in the late Ottoman Empire.” They also neglect “the role that Syrians t...

About a century before the birth of Jesus, during the reign of Emperor Wu of the Han Dynasty, a remarkable man began a nearly unprecedented intellectual endeavor. Sima Qian, like his father before him, was an official in the imperial court. Working on a plan left behind by his father, Sima Qian began writing a history of China for the two thousand years before his own time. The scope of his labors, and the historiographical discipline and philosophy of history that he brought to them, make him a sort of combination of Herodotus, Thucydides, Livy, and Plutarch. Yet in...

In this short episode, Al introduces a new feature of the Historically Thinking podcast: the Historically Thinking Field Guides. Drawing on nearly 450 past episodes, these guides gather conversations around major historical themes—beginning with a first guide devoted to the Second World War—so listeners can explore topics through curated sets of episodes, questions, and commentary. Al also explains how the podcast is evolving on Substack, where listeners can receive expanded show notes, weekly “Friday Reflection” discussions with questions and reading lists, and future essays and collections of historical links. It’s a brief update on where the podcast is going in 2...

Apology: Helen Veit’s audio has a lot of “ducking”, in which a word or multiple words were clipped. This happened during the recording, and cannot be fixed in the audio edit. We'll work hard to make sure this never happens again.

In nineteenth-century America, cookbook authors, concerned doctors, and food reformers believed that children had a problem with food. Children, reformers worried, would “eat anything and everything.” If they were to grow into healthy adults, they needed a special diet—“children’s food”—which meant that for the first time in human history children would have...

During the American Civil War an estimated 194,000 Union soldiers and 214,000 Confederate soldiers became prisoners of war. No prior or subsequent American conflict has seen such numbers. During the Second World War, approximately 124,000 Americans were held captive, but the chance of being captured in that conflict was roughly one in one hundred; during the Civil War it was closer to one in five. Captivity was not a marginal experience. It was central to the war.

Indeed, the gigantic scale of prisoner-of-war camps was one of the conflict’s most consequential innovations. Every modern war since has pr...

Lutherans are a strange denomination in American religious history and culture. For Catholics they are certainly Protestants. For Protestants they are crypto-Catholics. While they have been around since the Swedes established their short-lived colony on the Delaware River, they have typically received as much attention in the American imagination as the short-lived Swedish colony on the Delaware River. 

But my guest Timothy D. Grundmeier has a different point of view. He argues in his new book Lutheranism and American Culture: The Making of a Distinctive Faith that Lutheranism was a central component of nineteenth-century American r...

The two hundred and eighty years between the death of the philosopher Confucius and the reign of the first Emperor of China saw one of the most profound revolutions in human history. Not only did it end with the creation of an imperial rule that persisted through successive dynasties for 2,132 years, but it also saw the creation of “new traditions of thought and practice…great monuments of art, literature, and philosophy…that still inform social life in our own lifetime.” The era of the “warring states”, as scholars call it, was critical not just for China or East Asia, “but to that of...
