Indian Ocean 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.

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.

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.
