Click any event on the timeline to open it. Watch how each era flows into the next — cause and effect made visible. Navigate by era or scroll the full sweep from 1607 to the present.
Every event was caused — and caused something else. The Stamp Act didn't come from nowhere — it came from war debt. The Revolution didn't end with Yorktown — it produced the Constitution. Understanding causation is the difference between memorizing history and thinking historically.
