Rulers
The line of King of the United Kingdom of Portugal, Brazil and the Algarve - the office this state names as its head of state.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| John VI of Portugal | 1816 – 1822 | 6 years | left office aliveread off the dates alone |
2 rulers, 1 with terms dated as terms, covering 1816 – 1822. 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”.
