Fall of Constantinople
The Ottoman Empire under Sultan Mehmed II conquered Constantinople, ending the Byzantine Empire and the last vestige of the Roman Empire.
Preceding Causes
Ottoman military expansion, weakened Byzantine state, failure of Western Crusades, and Mehmed II's use of gunpowder artillery.
Ottoman Empire
One of history's most powerful and long-lasting empires, the Ottoman state controlled Anatolia, much of the Middle East, North Africa, and southeastern Europe for over six centuries, serving as the seat of the Islamic Caliphate from 1517.
Crusades
A series of religious wars launched by Latin Christian Europe aimed at capturing and holding Jerusalem and the Holy Land from Muslim rule, spanning nearly two centuries and nine major expeditions.
Historical Consequences
Ended the Byzantine Empire, shifted trade routes to sea, triggered Greek scholars' migration to Italy, and fueled the Renaissance.
Spanish Colonization of the Americas
Following Columbus's 1492 voyage, Spain conquered and colonized vast territories in the Americas, destroying the Aztec and Inca empires, subjugating indigenous populations, and extracting enormous mineral wealth.
Age of Exploration
European maritime nations launched expeditions that mapped the globe, connected continents, and transformed world trade, culture, and power dynamics between 1400–1600.
