Prince Henry the Navigator: Exploration, Ambition, and the Roots of the Slave Trade

The ocean was a wall of fear—until one man decided to break it, changing the course of human history forever. ​In this documentary, we explore the dual legacy of Prince Henry the Navigator (Infante Dom Henrique). While history books often paint him solely as a visionary of maritime science, his ambitions sparked a transformation that was as devastating as it was revolutionary. ​We track Henry’s transition from a royal sponsor of Atlantic exploration to the man widely credited with initiating the systematic European slave trade. In the 1440s, under Henry's direct orders and financial backing, Portuguese expeditions moved beyond mere fishing and mapping to the capture and transport of the first enslaved Africans to Lagos, Portugal. ​What you’ll learn in this video: ​The Science of Discovery: How the invention of the caravel allowed Portugal to push past Cape Bojador. ​The 1444 Turning Point: The grim reality of the first large-scale arrival of enslaved people in Europe. ​Economic vs. Religious Motives: Was Henry driven by the search for "Prester John," or the gold and human labor of the Guinea coast? ​A Systemic Shift: How Henry’s private "Company of Lagos" laid the groundwork for the Atlantic Slave Trade that would define the centuries to follow. ​From the navigation schools of Sagres to the tragic markets of the Algarve, this film examines how one man’s quest for discovery built a bridge between continents—and a system of exploitation that would haunt the world for generations. ​Disclaimer ​This documentary contains historical discussions regarding the origins of the Atlantic slave trade, including depictions and descriptions of human trafficking and systemic exploitation.
