Where it sits in time
Five thousand years, 3000 BCE to 2026; the state in gold.
Rulers
The line of king.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| Gongsun Yuan | 237 – 238 | 1 year | ending not on record |
1 rulers, 1 with terms dated as terms, covering 237 – 238. Only 1 years of the line are dated - too short for a median. A blank in the last column means no kin on record, which is coverage, never “unrelated”.
What happened within it, by century
Every row the atlas hosts under this state, by the century it began in: wars and battles in red, risings, regime changes and massacres beside them, everything else in grey. A tall bar is a century the record is full for, which is partly a fact about Wikipedia.
1 rows, over a span too long to list by century.
