The Dynastic Cycle
Good harvests swell the population and fill the treasury, funding order and earning the Mandate of Heaven — until overcrowding, corruption, and disaster erode it toward rebellion and reset. Nudge the tax, corruption, and disaster sliders and watch the coupled curves push your empire through founding, golden age, decline, and collapse. Drag across the chart to inspect any year of the record.

Why it matters
Why explore this?
History is about change over time and the choices that shape it. This model helps you compare causes, consequences, and patterns without treating the past as a list of dates.

Questions to test
Predict first, try it in the model, then use what you observe to answer.
What to try
- With low taxes and little corruption, can a single dynasty hold the Mandate for centuries — or does something always break the calm?
- Crank taxes past 30%. The treasury swells at first, so why does the Mandate start falling anyway?
- Set corruption high but taxes low. Where does all the harvest go, and why can't the state pay for order?
- Push disasters to the maximum. Do collapses come faster — and does the population ever recover between them?
- Right after a rebellion the population is tiny but the Mandate rebounds. What is it about an empty, well-fed land that founds a golden age?
Explain
Make sense of what happened
Build an explanation with a cause, a change, and a consequence. Then identify evidence from the model and one limitation of what the model can show.
