How it ended, as its article says
Dissolved, 1821-09-28. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
On September 28, 1821, Lucio Norberto Mansilla was elected Governor of the Province of Entre Ríos, and the Republic was subsequently dissolved.

Rulers
Read from the state’s own English article and its rulers’ articles, where Wikidata names no ruler.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| Francisco Ramírez | 1820 – 1821 | 1 year | ending not on record |
1 rulers, 1 with terms dated as terms, covering 1820 – 1821. 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”.
Flags and arms, in order
Each symbol with the years its own statement gives; the timeline flies the one of the year on screen.
