How it ended, as its article says
Dissolved, 1800-07-04. Read from the article's section “lead” by its grammar; the claim is only that the article says so.
Reduced to present-day Ohio, and some additional lands north and east on July 4, 1800, it ceased to exist March 1, 1803, when the southeastern portion of the territory was admitted to the Union as the state of Ohio, and the remainder attached to Indiana Territory.

Rulers
The line of Governor of Northwest Territory.
| Ruler | Reign | Length | How it ended · source | To the ruler before |
|---|---|---|---|---|
| Arthur St. Clair | 1788 – 1802 | 14 years | left office aliveread off the dates alone | |
| Charles Willing Byrd | 1802 – 1803 | 1 year | left office aliveread off the dates alone |
2 rulers, 2 with terms dated as terms, covering 1788 – 1803. Only 15 years of the line are dated - too short for a median. 0 of 1 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. 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.

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.

What led to it, and what came of it
The investigation's own picture: 4 causes the record names and 2 results, the strongest six of each at their own years, joined to the state by the kind of claim - a recorded statement solid, the article's sentence dashed, a theory dash-dot.
