1. Qin Shi Huang unifies China and declares himself its first emperor 221 BCE

   He standardized writing, currency, and axle widths — and was buried with an estimated 8,000 life-sized terracotta soldiers, no two faces alike.

2. The Aztecs found Tenochtitlan on an island in a lake 1325

   Legend says they built where an eagle perched on a cactus eating a snake — the image now at the center of Mexico's flag. Mexico City stands on the drained lakebed.

3. James Watt patents his improved steam engine 1769

   Watt also coined 'horsepower' as a marketing tool — comparing his engines to the draft horses customers would be replacing. The watt unit is named for him.

5. India and Pakistan gain independence from Britain 1947

   Independence came at midnight, and the hastily drawn border triggered one of history's largest migrations — some fifteen million people crossed in both directions.
