It boggles the mind to think that when the Taino people walked out onto the beaches of San Salvador and looked at Christopher Columbus, they weren’t just looking at men from another country; they were looking across a 15,000-year-old canyon of human separation. Columbus’s men brought weapons, clothes, and concepts forged by thousands of years of European, Asian, and African collision. But they also brought diseases that had never existed in the New World. In this episode, were going to talk about how the geographic isolation that had allowed these two worlds to grow into distinct, beautiful masterpieces was about to become the New World’s undoing.

When the news reached Venice that Vasco da Gama had made it all the way to India and back by ship, the Venetians knew that their monopoly on selling luxury goods from Asia was over. The task of breaking the news to the Doge of Venice fell to Piero Pasqualigo, the Venetian diplomat stationed in Lisbon. Throughout the 1400s, European states like Portugal, Castile, and Venice were locked in a battle for trade dominance. Venice guarded its Mediterranean strongholds (meaning), Castile and Portugal looked outward to the uncharted Atlantic. With every new island that Portugal claimed, its neighbor Castile looked for ways to increase its own regional and global influence. This decades-long competition for trade ignited an age of discovery that permanently shifted the global balance of power from the Mediterranean to the Atlantic. In this episode, we look at how these power struggles played out.

This was a century when European explorers were traveling farther than they had ever gone before from their own shores. Ferdinand and Isabella were competing with the Portuguese to find routes to travel to Southern Asia. These routes were incredibly valuable, as merchants could buy large quantities of luxury goods such as spices like pepper and cinnamon, porcelain, ivory, cotton, or even silk, then bring them back to Europe and sell them at a huge profit. But these voyages were also very risky. Signing on to a voyage of exploration was a bit like buying a lottery ticket, where you had just as good a chance of earning a fortune as you did of never returning. It is astonishing to imagine just how many sailors were willing to accept this risk and set sail for unknown shores, often without having any idea precisely where their destination was. Until 1434, European sailors would sail no further than Cape Bojador on the coast of Morocco. They were afraid that the currents and winds would never allow them to sail back northwards. But within less than a hundred years, an expedition sponsored by the Spanish crown would manage to sail all the way around the world.
