Ep# 142: Markets, Empire, and the Rise of Piracy

This episode explores how the rise of global trade in the seventeenth and eighteenth centuries unintentionally created the conditions for piracy to flourish. As European empires like Spain, England, France, and the Dutch Republic expanded across the Atlantic, they built vast systems of trade connecting sugar plantations, silver mines, colonial ports, and merchant fleets into one emerging global economy. But the ocean could never be fully controlled. Invisible trade routes carried enormous wealth across unpredictable seas, and wherever wealth moved in predictable patterns, opportunity for piracy followed. Mr. Palumbo tries to make the point that piracy was not random chaos, but an economic response to the deeper pressure of demand itself. The same demand that drove empires to build merchant fleets and expand global trade also created incentives for people willing to operate outside the law. As the episode argues, whenever demand becomes large enough, someone will always step forward to meet it—no matter the danger, the violence, or the risk involved.

Ep #141: The Limits of Total War: From Gentlemen's War to War in the 21st Century

In this episode of the Professor Liberty Podcast, we step back from the headlines and trace the evolution of war itself, asking a deeper question: what happens when overwhelming force no longer produces clear victory? From the restrained “gentlemen’s wars” of early modern Europe, where conflicts were limited and civilians largely stood apart, to the industrial-scale destruction of the American Civil War, we follow the steady expansion of conflict beyond battlefields and into the fabric of society. Along the way, we explore how World War I transformed war into a grinding system of attrition, and how World War II pushed total war to its absolute peak, where entire cities became targets and destruction reached unprecedented levels. The result is a world where war is constant but rarely decisive, and where the line between victory and catastrophe becomes increasingly blurred, forcing us to reconsider whether “winning” a war still means what we think it does.

Ep#140: The President and the War Machine

Step right up, ladies and gentlemen, boys and girls, unwanted pets and relatives! It’s your favorite obscure social studies teacher, Mr. Palumbo, back with the Professor Liberty Podcast. In this episode, a continuation of the discussion started in Episode 93, “The Citizen and the War Machine,” we zoom in from society at large to the commander-in-chief, exploring how U.S. presidents navigate the pressures of hawkish advisers, the Pentagon, intelligence agencies, and the military-industrial complex. From Woodrow Wilson’s reluctant entry into World War I to Donald Trump’s modern military strikes on Iran, we examine how campaign promises of peace often collide with geopolitical realities, showing how for better or worse, even cautious presidents can be swayed into conflict.

Ep#139: From Iberia to the Great Plains: How Spain Built the Cowboy

In this episode of the Professor Liberty Podcast, we saddle up and ride through history to explore the true origins of the American cowboy. From Secretary of State Marco Rubio’s shout-out at the Munich Security Conference to Spain’s role in bringing horses, ranching, and the vaquero tradition to the New World, to the Comanche’s legendary mastery of the horse that reshaped the Plains, to Black cowboys like Bill Pickett who innovated rodeo culture and bulldogging, we cover it all. We’ll dig into daily life on the trail, food, pay, and the rugged individualism that forged frontier life, while showing how the cowboy is really a tapestry of Spanish, Indigenous, African American, and broader Western European contributions: a living symbol of freedom, skill, and ingenuity that helped define the American ethos.

Ep #138 Boats of Death: Inside WWII's most deadliest Submarines

From hand-cranked wooden death traps to steel predators stalking the depths, this episode of the Professor Liberty Podcast dives deep into the deadliest submarines of World War II and the men who dared to serve aboard them. Mr. Palumbo traces the origins of submarine warfare from the American Revolution to the Atlantic and Pacific battlefields, explains why submarines are still called “boats,” and unpacks the brutal reality of life inside a cramped, airless steel tube where one mistake could mean death for everyone aboard. Along the way, we meet legendary vessels like Germany’s U-48 and U-99 and America’s USS Tang, explore the tactics and commanders that made them so lethal, and confront the human cost behind every ton sunk. It’s a story of innovation, strategy, fear, and endurance—where oceans became chessboards, submarines reshaped global warfare, and courage turned even the smallest boat into a legend.
