The RMS Titanic is history’s most famous shipwreck, but it wasn’t the only ship of its kind. The White Star Line built two other nearly identical vessels: The RMS Olympic and Britannic. The Olympic carried passengers until 1935 and can be visited today. The Brittanic sank only four years after her sister ship the Titanic off the Greek island of Kea in the Aegean Sea like due to striking a German mine while serving as a hospital ship during World War One. It sank in only 55 minutes (compared to 160 minutes for the Titanic) but only 30 of the 1066 passengers due to better lifeboat procedures, warmer waters, and being closer to land. What While the wreck of the Titanic is 2 miles below the surface and rapidly deteriorating, the Britannic is much more accessible (only 400ft down) and remains largely intact. It’s in “shallow” enough waters that divers can reach it, although submersibles do most of the investigation work. What can the ship tell us about the sinking of the Titanic, the lives of its passengers in the early 20th century, and whether something nefarious happened that caused it to sink, as some claim (like German sabotage). These are the questions that today’s guest, Simon Mills, tried to answer when bought the wreck of the Britannic in 1996. He is a maritime historian who has coordinated multiple expeditions into the underwater wreckage and most recently finished extensive internal surveys in 2021 and 2023. He’s also the author of the new book Inside the Britannic which is the sum of decades of work covering every inch of the ship. We discuss exactly how this ship sunk, what happened during the frantic 50 minutes of its sinking, what happened to the survivors, and other unanswered mysteries.

At a time when debates over tariffs, regulation, and the scope of government are back at center stage. Is this time in American history unprecedented, or can we find parallels in the past? For example, has trade “hollowed out” U.S. manufacturing—or have fact tariffs like the Corn Laws in Britain hurt working-class families the most? Was the Great Depression a failure of capitalism—rather than a policy crisis worsened by poor monetary responses and overreach? Today’s guest is Phil Gramm, a former U.S. Senator and author of “The Triumph of Economic Freedom.” We look at five periods of American history—the Industrial Revolution, Progressive Era, Great Depression, decline of America’s postwar preeminence in world trade, and the Great Recession—along with the existing levels of income inequality and poverty, leads many to believe in expanding government in American life. Gramm argues that the evidence points to a contrary verdict: government interference and failed policies pose the most significant threat to economic freedom.

Alan Pinkerton is perhaps the most over-achieving barrel-maker who ever lived. After practicing his trade in rural Illinois for a few years in the 1850s, the Scottish immigrant busted up a counterfeiting ring, which got the attention of Chicago’s police department, offering him a job as a detective. From here he worked as an intelligence agent in the Civil War (preventing an assassination attempt on Lincoln’s life), then pursued high-profile outlaws like Butch Cassidy and the Sundance Kid, and protected scabs in the Homestead lockout, for which his private detective agency became notorious. Pinkerton has been an enduring source of fascination since the nineteenth century. But the details of his impact, business empire, and private life have been incomplete. Today’s guest is Rhodri Jeffreys-Jones, author of “Allan Pinkerton: America's Legendary Detective and the Birth of Private Security.” We discuss the accomplishments, contradictions, controversies, and legacies of the founder of the Pinkerton National Detective Agency.

The Korean War came dangerously close to going nuclear, and if would have if Gen. Douglas MacArthur had gotten his way. He proposed using 30 to 50 nuclear primarily to targeting air bases, depots, and supply lines across the neck of Manchuria to create a radioactive barrier and halt Chinese and North Korean advances. This would have killed millions and almost definitely brought the Soviet Union into full-scale war against the United States. In this episode, we explore the Korean War’s pivotal role in shaping the Cold War, diving into the tense standoff between East and West. The conflict erupted with North Korea’s 1950 invasion, prompting a daring counteroffensive by MacArthur, whose strategic overreach drew Communist China into the fray. The rapid escalation pushed the U.S. to contemplate using nuclear weapons, a decision that could have reshaped the 20th century. To explore this is today’s guest, Robert Lyman, author of “Korea: War Without End.” The Korean War was not planned as a Communist offensive against the West. In turn, the East did not understand the principle at the core of the Western response to Kim Il-sung’s aggression, namely a refusal to appease an aggressor, the key mistake the West considered to be at the heart of the rise of Nazi Germany and militaristic Japan in the 1930s.

Rome’s Western Empire may have fallen 1,600 years ago, but its cultural impact has a radioactive half-life that would make xenon jealous. Over a billion people speak Latin (or at least a Latin-derived language). Governments around the world self-consciously copy Roman buildings and create governments that copy the imperial senate. Every self-aggrandizing leader has compared himself to Caesar, including those with a strong claim (Charlemagne and Napoleon) and those with a weaker one (Idi Amin and Muammer Gaddafi). But what if the Roman Empire never truly fell? This is the perspective of today’s guest, Aldo Cazzullo, author of “The Neverending Empire: The Infinite Impact of Ancient Rome. Rome’s influence is not just a relic of history—it’s the foundation of the modern West and nowhere is that more evident than in the United States. While many political empires throughout history have presented themselves as the true heirs of Rome, Cazzullo contends that it’s the US, that most resembles the Roman Empire. It’s an angle with which to view America’s story/where it’s heading and most importantly, what we can learn to ensure that we can look forward to another 3000 years.

In order to become rich, powerful, and prestigious in the pre-modern world, nothing mattered more than horses. They were the fundamental unit of warfare, enabling cavalry charges, and logistical support. They facilitated the creation of the Silk Road (which could arguably be called the “Horse Road”) since China largely built it to enable the purchase of millions of horses to fight its nomadic neighbors to the north. The term "caballero," meaning a gentleman or knight in Spanish, derived from the Latin "caballus" (horse), reflecting how wealth, status, and the skilled ability to ride a horse defined chivalric ideals in medieval society. From the windswept Eurasian steppe to the royal stables of Persia and the warpaths of Genghis Khan, today’s guest, David Chaffetz, author of Raiders, Rulers, and Traders traces the story of how horses changed the world—not just in warfare, but in statecraft, commerce, and culture. Chaffetz makes the case that the so-called “Silk Road” might more accurately be remembered as the Horse Road. Horse-driven mobility shaped empires from Assyria and the Achaemenids to the Mughals and the Soviets. Just as we rely on the Internet today, ancient societies depended on the horse as a transformative technology that shaped everything from warfare to governance.

The Prohibition era (1920–1933), enacted by the 18th Amendment, birthed an overnight economy of moonshiners who distilled and distributed homemade liquor to meet America’s insatiable demand for alcohol, transforming rural farmers and opportunists into underground entrepreneurs who supplied speakeasies. But this new economy didn’t disappear after Prohibition was repealed. If anything, it became stronger, at least in the South. Moonshining persisted due to persistent poverty, high liquor taxes, and entrenched cultural traditions in the rural South, where Bible Belt traditions meant respectable folks didn’t want themselves to be seen at bars or liquor stores. It grew in the 1940s and only disappeared when industrial distillers were able to produce spirits that undercut moonshine prices. To explore this topic is Chris Skates, author of “Moonshine Over Georgia.” A historical fiction novel, it pulls from the harrowing, exciting, and very real stories Chris’ grandfather would tell him growing up, working as a revenue agent in Prohibition-era Georgia.

What comes to mind when we think about the Sahara? Rippling sand dunes, sun-blasted expanses, camel drivers and their caravans perhaps. Or famine, climate change, civil war, desperate migrants stuck in a hostile environment. The Sahara stretches across 3.2 million square miles, hosting several million inhabitants and a corresponding variety of languages, cultures, and livelihoods. But beyond ready-made images of exoticism and squalor, we know surprisingly little about its history and the people who call it home. That’s not for a lack of trying. The Romans tried to cross the Sahara, going back as least as far as Cornelius Balbus (19 BC): Starting from Sabratha in Libya, Balbus led a force of 10,000 legionaries to conquer the Garamantes in the Fezzan region (modern Libya). He then sent a smaller group south across the Ahaggar Mountains, likely reaching the Niger River near modern Timbuktu in Mali, traveling over 1,000 miles inland. Ibn Battuta, the medieval explorer, experienced the wealth of West Africa’s vast gold mines long before the Portuguese made their way down the African coast. Today’s guest is Judith Scheele, author of “Shifting Sands: A Human History of the Sahara.” We see how the desert is not the empty wasteland of the romantic imagination but the vast and highly differentiated space in which Saharan peoples and, increasingly, new arrivals from other parts of Africa live, work, and move. It takes us from the ancient Roman Empire through the colonial era, whose future holds implications for us all. See omnystudio.com/listener for privacy information.

As many as 100,000 enslaved people fled successfully from the horrors of bondage in the antebellum South, finding safe harbor along a network of passageways across North America via the Underground Railroad. Yet many escapes took place not by land but by sea. William Grimes escaped slavery in 1815 by stowing away in a cotton bale on a ship from Savannah to New York, enduring days without food or water before settling in Connecticut. Frederick Douglass disguised himself as a free black sailor, using borrowed papers to board a train and then a steamboat from Baltimore to New York, reaching freedom in less than 24 hours. Thomas Jones, a formerly enslaved man from North Carolina, escaped in 1849 by hiding on a ship bound for New York, relying on his maritime knowledge as a steward to evade detection and later reuniting with his family in the North. This was a secret world of stowaways and the vessels that carried them to freedom across the North and into Canada. It sprawled through the intricate riverways of the Carolinas to the banks of the Chesapeake Bay to Boston’s harbors. Today’s guest is Marcus Rediker, author of “Freedom Ship: The Uncharted History of Escaping Slavery by Sea.” We see the Atlantic waterfront as a place of conspiracy, mutiny, and liberation.

2025 marks the eightieth anniversary of Germany’s surrender and the fall of the Third Reich. Likewise, World War II is the single most studied conflict in human history. But most Western accounts offer a one-dimensional interpretation: the war was a noble crusade against fascism, creating a convenient parable about good and evil. But this depiction ignores a far messier reality. But what went through the minds of the actual heads of state that led their nations through the war? Did they fight according to our understanding, or did they want to defend their nations’ global empires and ancient legacy? A case can be argued that World War II was not a battle in which democracy triumphed over totalitarianism but rather a massive colonial war waged by rival empires. The war formally ended the era of British and Japanese colonialism but established in their places the highly militarized Soviet and American states, whose access to nuclear weapons threatened the possibility of annihilation. As we grapple with the legacy of the war and its influence on geopolitics today, historian and today’s guest Paul Thomas Chamberlin urges us to reconsider the conflict from a new perspective in his book “Scorched Earth: A Global History of World War II.” See omnystudio.com/listener for privacy information.

As the American Revolution broke out in New England in the spring of 1775, dramatic events unfolded in Virginia that proved every bit as decisive as the battles of Lexington and Concord and Bunker Hill in uniting the colonies against Britain. Virginia, the largest, wealthiest, and most populous province in British North America, was led by Lord Dunmore, who counted George Washington as his close friend. But the Scottish earl lacked troops, so when patriots imperiled the capital of Williamsburg, he threatened to free and arm enslaved Africans—two of every five Virginians—to fight for the Crown. Virginia’s tobacco elite was reluctant to go to war with Britain but outraged at this threat to their human property. Dunmore fled the capital to build a stronghold in the colony’s largest city, the port of Norfolk. As enslaved people flocked to his camp, skirmishes broke out. “Lord Dunmore has commenced hostilities in Virginia,” wrote Thomas Jefferson. “It has raised our countrymen into a perfect frenzy.” With a patriot army marching on Norfolk, the royal governor freed those enslaved and sent them into battle against their former owners. In retribution, and with Jefferson’s encouragement, furious rebels burned Norfolk to the ground on January 1, 1776, blaming the crime on Dunmore. The port’s destruction and Dunmore’s emancipation prompted Virginia’s patriot leaders to urge the Continental Congress to split from Britain, breaking the deadlock among the colonies and leading to adoption of the Declaration of Independence. Days later, Dunmore and his Black allies withdrew from Virginia, but the legacy of their fight would lead, ultimately, to Abraham Lincoln’s 1863 Emancipation Proclamation. Chronicling these stunning and widely overlooked events in full for the first time is today’s guest, Andrew Lawler, author of A Perfect Frenzy: A Royal Governor, His Black Allies, and the Crisis that Spurred the American Revolution. He offers a new perspective on the American Revolution that reorients our understanding of its causes, highlights the radically different motivations between patriots in the North and South.

He was a gutsy old man.” “A corker,” said another. “You couldn’t find anyone better.” They talked about him in hushed tones. “This Major Carlson,” wrote one of the officers in a letter home, “is one of the finest men I have ever known.” These were the words of the young Marines training to be among the first U.S. troops to enter the Second World War—and the Major Carlson they spoke of was Evans Carlson, a man of mythical status even before the war that would make him a military legend. By December of 1941, at the age of forty-five, Carlson had already faced off against Sandinistas in the jungles of Nicaragua and served multiple tours in China, where he embedded with Mao’s Communist forces during the Sino-Japanese War. Inspired by their guerilla tactics and their collaborative spirit—which he’d call “gung ho,” introducing the term to the English language—and driven by his own Emersonian ideals of self-reliance, Carlson would go on to form his renowned Marine Raiders, the progenitors of today’s special operations forces, who fought behind Japanese lines on Makin Island and Guadalcanal, showing Americans a new way to do battle. Today’s guest is Stephen R. Platt, author of “ “The Raider: The Untold Story of a Renegade Marine and the Birth of U.S. Special Forces in World War II.” Tracing the rise and fall of an unlikely American war hero, The Raider is a story of exploration, of cultural (mis)understanding, and of one man’s awakening to the sheer breadth of the world.

Scientists and enthusiastic amateurs first confirmed the existence of living things invisible to the human eye in the late sixteenth century. So why did it take two centuries to connect microbes to disease? As late as the Civil War in the 1860s, most soldiers who perished died not on the battlefield but of infected wounds, typhoid, and other diseases. Twenty years later, the outcome might have been different, following one of the most radical intellectual transformations in history: germ theory, the recognition that the tiniest forms of life have been humankind’s greatest killers. It was a discovery centuries in the making, and it transformed modern life and public health. As today’s guest, Thomas Levenson (author of “So Very Small: How Humans Discovered the Microcosmos, Defeated Germs—and May Still Lose the War Against Infectious Disease”) reveals in this globe-spanning history, it has everything to do with how we see ourselves. For centuries, people in the West, believing themselves to hold dominion over nature, thought too much of humanity and too little of microbes to believe they could take us down. When nineteenth-century scientists finally made the connection, life-saving methods to control infections and contain outbreaks soon followed. The next big break came with the birth of the antibiotic era in the 1930s. And yet, less than a century later, the promise of the antibiotic revolution is already receding due to years of overuse. Is our self-confidence getting the better of us again? So Very Small follows the thread of human ingenuity and hubris across centuries—along the way peering into microscopes, spelunking down sewers, visiting army hospitals, traipsing across sheep fields, and more—to show how we came to understand the microbial environment and how little we understand ourselves. Levenson traces how and why ideas are pursued, accepted, or ignored—and hence how human habits of mind can, so often, make it terribly hard to ask the right questions.

The story of the atomic age began decades before Robert Oppenheimer watched a mushroom cloud form over the New Mexico desert at the Trinity nuclear test in mid 1945. It begins in 1895, with Henri Becquerel’s accidental discovery of radioactivity, setting in motion a series of remarkable and horrifying events. By the early 20th century, a brilliant group of scientists—including Ernest Rutherford, Leo Szilard, Enrico Fermi, and others—were pushing the boundaries of knowledge, seeking to answer fundamental questions about this source of energy that had 2 million times the energy density of oil: What is this mysterious radiation? Could it provide an infinite energy source, where a basketball of it was equal to an oil field? And, ominously, could it be weaponized? Today’s guest is nuclear physicist Frank Close, author of “Destroyer of Worlds: The Deep History of the Nuclear Age.” We look at the complete history of the atomic age, from the initial curiosity about radioactivity to the creation of the hydrogen bomb—a weapon of almost unimaginable destructive potential, capable of eradicating life on Earth. This is an account of the scientific discoveries that unlocked the atom’s power, the ethical dilemmas faced by scientists, and the horrifying realization that this newfound energy could lead to humanity’s undoing.

The B-29 Bomber led the Allied strategic bombing offensive against Japan, succeeding when US Bomber Command switched from high-level daytime precision bombing to low-level nighttime area bombing. The latter tactic required Superfortresses to attack their targets individually, without a formation or escorting fighters for protection. Despite this, Japanese night fighters proved unable to stop the B-29s. This success was a testament to the B-29’s incredible capabilities, including its ability to carry up to 20,000 pounds of bombs over vast distances exceeding 3,000 miles, and its advanced pressurized cabin, which allowed crews to operate effectively at altitudes above 30,000 feet—far beyond the reach of most enemy interceptors. Coupled with its sophisticated remote-controlled gun turrets and a top speed of 350 mph, the B-29’s design showcased an unmatched blend of range, payload, and defensive prowess that overwhelmed Japanese defenses. Today’s guest, Mark Lardas, author of “B-29 Superfortress vs Japanese Nightfighter.” He examines the capabilities of the aircraft involved, and reveals the conditions under which both sides fought. He evaluates the cutting-edge technology of both sides and how it affected the outcome of the battle See omnystudio.com/listener for privacy information.

Throughout the war on the Eastern Front, there were two consistent trends. The Red Army battled to learn how to fight and win, while involved in a struggle for its very survival. But by 1944 it had a leadership that was able to wield it with lethal effect and with far more effective equipment than before. By contrast, the Wehrmacht had commenced a slow process of decline after the invasion of the Soviet Union. Hitler became increasingly unwilling to delegate decision-making to commanders in the field, which had been crucial to earlier success. The long years of fighting had also taken a heavy toll. Thousands of irreplaceable junior officers and NCOs were dead, wounded or prisoners. Today’s guest is Prit Buttar, author of “Bagration 1944: The Great Soviet Offensive.” We look at these trends, which culminated in the huge battles of Bagration. In 1944, the Red Army finally put together a campaign that utterly destroyed the German Army Group Centre. The Wehrmacht suffered the loss of over 300,000 men killed, wounded or taken prisoner and the Red Army rolled forward across Belarus to the outskirts of Warsaw. The end of the war was still many months away, and the Germans managed to reconstruct their line on the Eastern Front, but final victory for the Soviet Union was now only a matter of time as a direct consequence of Bagration.

Pilgrimages are a universal phenomenon, from China’s bustling Tai Shan to the ancient Jewish treks to Jerusalem. But why? What is it about a grueling penitent march to an isolated temple that has become a prerequisite for a civilization of any size, whether Chicen Itza in the Mayan Empire or the holy sites of Mecca? To explore this is today’s guest, Kathryn Hurlock, author of “Holy Places: How Pilgrimages Changed the World.” We also look at whether pilgrimages have become too easy in the 21st century. Has jetting off to Mecca or Rome for a quick indulgence turned them into spiritual tourism, a la Disneyland? See omnystudio.com/listener for privacy information.

Years before Jamestown planters made New World farming profitable by growing tobacco, and years before their countrymen up north in Plymouth Colony managed to overcome their starvation conditions and acclimate to New England’s growing conditions, there was an English settlement in Bermuda that was wealthier, larger, and more prosperous. It was established in 1612 on an island less than one square mile but grew to the heart of the Atlantic economy. Bermuda, once home to more settlers than Virginia or Massachusetts, became England’s first profitable plantation, pioneering tobacco cultivation and the use of enslaved Africans—practices that later spread to the mainland. In this episode, historian and archaeologist Michael Jarvis joins us to uncover the hidden history of Bermuda and its pivotal role in reshaping our understanding of colonial America. Jarvis, dubbed "Chainsaw Mike" by his students, has spent 14 years excavating Smith’s Island, clearing away endless brush, and unearthing one of the first English settlements in the New World. From supplying Jamestown with food to influencing early colonial economics, Jarvis argues Bermuda is a missing cornerstone of America’s origin story, far more than the historical footnote it’s often been relegated to.

The origins of the Hatfield-McCoy conflict (between the Hatfield family of West Virginia, led by William Anderson "Devil Anse" Hatfield, and the McCoy family of Kentucky, led by Randolph "Old Randall" McCoy) begins with a dispute over a pig. From here, it escalated from minor disagreements to violent encounters that spanned decades, nearly sparking a war between the two states. Today’s guest is Jennifer Bennie, host of the Walk With History podcast. We look at the historical context of the feud, its escalation from minor disputes to violent encounters, and its significance in American folklore.

In 1845, a novel pathogen attacked potato fields across Europe, from Spain to Scandinavia—but only in Ireland were the effects apocalyptic. At least one million Irish people died, and millions more scattered across the globe, emigrating to new countries and continents. Less than fifty years after the union of Ireland with the rest of Great Britain, the newly formed United Kingdom—the most powerful country in the nineteenth-century world—failed millions of its own citizens, leading to decades of poverty, ecological ruin, and collective trauma. How did this happen? Today’s guest Padraic Scanlan recontextualizes the disaster’s origins, events, and consequences in his new book “Rot: An Imperial History of the Irish Famine.” We situate the Irish Great Famine in a larger history of economic consolidation and exploitation caused by British policies toward Ireland. The blight that decimated the potato plants was biological, but the Famine itself was manmade, caused by the British government’s structures of land ownership, labor, and rent collection. The real tragedy of the Famine wasn’t that the British maliciously intended and propagated starvation, but that their efforts to address the “Irish Question” only exacerbated the problem.
