Rulers
The line of Duke of Neopatras - the office this state names as its head of state.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| Peter IV of Aragon | 1381 – 1387 | 6 years | died in office, manner not recordedread off the dates alone |
1 rulers, 1 with terms dated as terms, covering 1381 – 1387. Only 6 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”.
