📖 The Day the World Ended
📖 The Day the World Ended
In November 1519, the Aztec emperor Moctezuma II walked out of the greatest city in the Western Hemisphere to greet a bearded stranger. Tenochtitlan had perhaps 200,000 inhabitants — five times the size of contemporary London. Its canals, pyramids, and floating gardens were beyond anything the Spanish had imagined. And yet within two years, it would be rubble.
The story of the Spanish Conquest is not simply a tale of superior weapons defeating a primitive foe. It is a story of diplomacy, disease, betrayal, alliance, and catastrophic misunderstanding — one of the most complex and consequential encounters in human history.
By 1519, the Aztec Triple Alliance — formed between Tenochtitlan, Texcoco, and Tlacopan in 1428 — dominated central Mexico. The empire controlled around 5 to 6 million people across roughly 200,000 square kilometres.
