Before 1862, Joshua Lawrence Chamberlain had rarely left his home state of Maine, where he was a trained minister and mild-mannered professor at Bowdoin College. His colleagues were shocked when he volunteered for the Union army, but he was undeterred and later became known as one of the North’s greatest heroes: On the second day at Gettysburg, after running out of ammunition at Little Round Top, he ordered his men to wield their bayonets in a desperate charge down a rocky slope that routed the Confederate attackers. Despite being wounded at Petersburg—and told by two surgeons he would die—Chamberlain survived the war, going on to be elected governor of Maine four times and serve as president of Bowdoin College. How did a stuttering young boy come to be fluent in nine languages and even teach speech and rhetoric? How did a trained minister find his way to the battlefield? To explore Chamberlain’s fascinating story is today’s guest, Ronald White, author of “On Great Fields: The Life and Unlikely Heroism of Joshua Lawrence Chamberlain.” He is presented from cradle-to-grave in all his ideals, tenacity, and contradictions.

During Theodore Roosevelt’s presidency—from 1901 to 1909, when Mark Twain called him the most popular man in America—his daughter Alice Roosevelt mesmerized the world with her antics and beauty. Alice was known for carrying a gun, a copy of the Constitution, and a green snake in her purse. When her father told her she couldn’t smoke under his roof, she climbed to the top of the White House and smoked on the roof. She became the most famous woman in America—and even the world—predating Princess Diana and Jackie Kennedy as an object of public obsession. As her celebrity grew, she continued to buck tradition, push against social norms, and pull political sway behind the curtain of privilege and access. She was known for her acerbic wit and outspoken tendencies which hypnotized both the social and political world. Today’s guest is Shelley Fraser Mickle, author of “White House Wild Child: How Alice Roosevelt Broke All the Rules and Won the Heart of America.” We explore what it would have been like to be a strong-willed, powerful woman of the 20th century aughts.

In 1923, the Weimar Republic faced a series of crises, including foreign occupation of its industrial heartland, rampant inflation, radical violence, and finally Hitler’s infamous “beer hall putsch.” Fanning the flames of anti-government and anti-Semitic sentiment, the Nazis tried to violently seize power in Munich, only failing after they were abandoned by like-minded conservatives. Today’s guest is Mark Jones, author of “1923: The Crisis of German Democracy in the Year of Putsch.” We discuss how the Nazis’ plan was initially to seize power in Munich, control Bavaria, then march on Berlin. Hitler needed the support of the military and the police, which he did not get in 1923 but did get in 1933. Tracing Hitler’s early rise, Jones reveals how political pragmatism and unprecedented international cooperation with the West brought Germany out of its crisis year. Although Germany would succumb to tyranny a decade later, the story of the republic’s survival in 1923 offers essential lessons about the future of democracy today.

Among the conflicts that convulsed Europe during the nineteenth century, none was more startling and consequential than the Franco-Prussian War of 1870–1871. Deliberately engineered by Prussian chancellor Otto von Bismarck, the war succeeded in shattering French supremacy, deposing Napoleon III, and uniting a new German Empire. But it also produced brutal military innovations and a precarious new imbalance of power that together set the stage for the devastating world wars of the next century. Today’s guest is Rachel Chrastil, author of “Bismarck’s War: The Franco-Prussian War and the Making of Modern Europe.” We see how the war reshaped and blurred the boundaries between civilian and soldier as the fighting swept across France by bolstering a unified Germany to contributing to the development of modern warfare.

Religious beliefs have been the source of food "rules" since Pythagoras told his followers not to eat beans (they contain souls), Kosher and Halal rules forbade the shrimp cocktail (shellfish are scavengers_, and the Catholic church forbade its peoples from eating meat on Fridays (fasting to atone for committed sins). Rules about eating are present in nearly every American belief, from high-control groups that ban everything except air to the infamous strawberry shortcake that sated visitors to the Oneida Community in the late 1800s. To explore the intersection of religion and modern diet is Christina Ward, author of “Holy Food: How Cults, Communes, and Religious Movements Influenced What We Eat.” The explosion of religious movements since the Great Awakenings that birthed a cottage industry of food fads and cookbooks. Ward uncovers the interconnectivity between obscure sects and communities of the 20th Century who dabbled in vague spirituality and used food to both entice and control followers.

The Pax Romana has long been shorthand for the empire’s golden age. Stretching from Caledonia to Arabia, Rome ruled over a quarter of the world’s population. It was the wealthiest and most formidable state in the history of humankind. Today we are speaking with Tom Holland, author of “Pax: War and Peace in Rome’s Golden Age” to explore Rome at the height of its power. From the gilded capital to realms beyond the frontier, we see ancient Rome in all its glory and cruelty: Nero’s downfall, the destruction of Jerusalem and Pompeii, the building of the Colosseum and Hadrian’s Wall, and the conquests of Trajan. Looking at the lives of Romans both ordinary and spectacular, from slaves to emperors, we see that Roman peace was the fruit of unprecedented military violence.

The first year of the siege of Leningrad that began in September 1941 marked the opening stage of a 900-day-long struggle for survival that left over a million dead. The capture of the city came tantalizingly close late that year, but Hitler paused to avoid costly urban fighting. Determined to starve Leningrad into submission, what followed was a winter of unimaginable suffering for ordinary citizens and defenders alike. First-hand accounts from Soviet and German soldiers, many never previously published, together with those of the civilians trapped in the city detail the relentless specter of death which defined life in and around Leningrad. Today’s guest is Prit Buttar, author of “To Besiege a City: Leningrad 1941-42.” Personal vignettes give a glimpse into the reality of life in a city under siege. The teenage volunteer climbers, weak from hunger, scaling the slender spire of the Peter and Paul Fortress to shroud it in camouflage as the German bombers circle overhead like vultures. Or the soldier trombonist completing a long day on the front line to perform Shostakovich’s epic Seventh Symphony alongside a starving and sickly orchestra – an act of defiance broadcast to defenders and attackers alike.

The Ku Klux Klan was arguably America’s first organized terrorist movement. It was a paramilitary unit that arose in the South during the early years of Reconstruction. At its peak in the early 1870s, the Klan boasted many tens of thousands of members, no small number of them landowners, lawmen, doctors, journalists, and churchmen, as well as future governors and congressmen. And their mission was to obliterate the small but growing economic and political power of newly emancipated black Americans and their white allies, often by the most horrifying means imaginable. To repel the virulent tidal wave of violence, President Ulysses S. Grant waged a two-term battle against both armed southern enemies of Reconstruction and northerners seduced by visions of post-war conciliation, testing for the first time the limits of the federal government in determining the extent of states' rights. To discuss this early history of reconstruction is today’s guest, Fergus M. Bordewich, author of “Klan War: Ulysses S. Grant and the Battle to Save Reconstruction.” We explore the hamlets of the former Confederate States and the marble corridors of Congress, analyzing key figures such as crusading Missouri Senator Carl Schurz and the ruthless former slave trader Nathan Bedford Forrest.

Heinrich Pfeifer was a senior member of the Nazi deep state who defected in 1938. He wrote his memoirs in 1945, with the goal of describing the inner workings of Nazi intelligence with enough detail to keep any of the members from escaping justice from the encroaching Allies. However, he was assassinated in 1949 after a pro-Nazi hit squad killed him, and copies of his work were mostly destroyed. However, today’s guest, Robert Temple, was able to obtain a copy and recently translated it to English. Temple is author of Drunk On Power: A Senior Defector’s Inside Account of the Nazi Secret Police State. It is the first complete description of the Nazi “Deep State” by its most senior defector, Pfeifer. We discuss a complete X-Ray of the structure of the Nazi Deep State and describe the international infiltration of Nazis into key institutions in every country in the world.

Many of the WW2 generation faced hardship in their youth (they did spend their childhood in the Great Depression), but few had as bad of an early life as Denis Elliott, who became an RAF Flight Lieutenant. At age three he was placed in a brutal and abusive orphanage in London and was later subject to beatings by his first foster father. It wasn’t until the Second World War that everything in Denis’s life began to change — he finally overcame the lack of confidence and self-esteem that had plagued his childhood in Kent and went on to become a skilled, confident, brave pilot flying operations against Japanese forces in Burma, Malaya and Thailand. He spent two stints serving in the RAF, which saw him posted across Africa, the Middle East, the Far East and Europe, flyingearning to flying B-24 Liberators and Avro Lancasters. Today’s guest is Phillip Martin, author of “From Orphan to High-Flyer.” We discuss these stories, along with those of Denis’s personal growth, friendship and overcoming adversity.
