Japanese Samurai Mercenaries in Portuguese Macau: 16th–17th Centuries Hardcover – January 22, 2026

Japanese Samurai Mercenaries in Portuguese Macau (16th–17th Centuries) reveals a remarkable yet largely forgotten chapter of global history, where displaced Japanese samurai—rōnin without masters—served as mercenaries in one of Europe’s earliest Asian colonies.Set against the turbulent backdrop of the Age of Discovery, this book explores how Portuguese Macau became a strategic crossroads linking Japan, China, and Europe. As Portugal struggled to defend its distant outpost from pirates, rival European powers, and political pressure from Ming China, it turned to an unexpected source of military strength: Japanese warriors forged in the brutal conflicts of the Sengoku period.Drawing on military history, geopolitics, and cultural exchange, Emanuel Maia examines:The rise of the rōnin following Japan’s unificationThe recruitment and daily lives of samurai in MacauTheir role in fortifications, garrison duty, and key conflicts such as the Dutch siege of MacauThe diplomatic tensions their presence created with Ming authoritiesThe lasting legacy of this early global mercenary phenomenonMore than a military history, this book is a study of early globalization—where commerce, warfare, and culture collided across continents. It will appeal to readers interested in samurai history, Portuguese expansion, East Asian geopolitics, and the hidden stories of cross-cultural encounters that shaped the modern world. Read more
