Indian Ocean History

Around eight o'clock a.m. on December 26, a massive earthquake registering 9.1-9.3 on the Richter Scale struck off of Sumatra, Indonesia, making it the third strongest earthquake ever recorded by seismographs. On top of that, the earthquake shook for nearly 10 minutes and generated incredibly strong tsunami waves. Thanks to the element of surprise, people in the region had virtually no warning of what was coming. The tsunami waves pulverized entire towns and swept away hundreds of thousands of people across Southeast Asia.

When did the first humans arrive in India and how did they get here? What are Roman artifacts from hundreds of years ago doing in a town near Puducherry? How did merchants from Arabia end up near Kochi? From the east coast of Africa to Australia, one big blue body of water has connected diverse peoples and cultures for thousands of years: the incredible Indian Ocean. Listen in to learn about the fearless travelers and sailors, pirates and conquerors who set out to cross the ocean in search of gold and glory, and discover how geography can shape the course of history.

As remarkable as Columbus and the conquistador expeditions, the history of Portuguese exploration is now almost forgotten. But Portugal's navigators cracked the code of the Atlantic winds, launched the expedition of Vasco da Gama to India and beat the Spanish to the spice kingdoms of the East - then set about creating the first long-range maritime empire.

The transatlantic slave trade was founded by the Portuguese in the 15th century for the specific purpose of supplying the New World colonies with African slave labor. It was soon joined by all the major trading powers of Europe, and it reached its peak in the 18th century with the founding and development of plantation economies that ran from the South American mainland through the Caribbean and into the southern states of the United States. The East African Slave Trade, on the other hand, was more complex, far older, and significantly more widespread.

In terms of geopolitics, perhaps the most seminal event of the Middle Ages was the successful Ottoman siege of Constantinople in 1453. The city had been an imperial capital as far back as the fourth century when Constantine the Great shifted the power center of the Roman Empire there effectively establishing two almost equally powerful halves of antiquity’s greatest empire. Constantinople would continue to serve as the capital of the Byzantine Empire even after the Western half of the Roman Empire collapsed in the late fifth century.
