Principality of Tver

Where it sits in time

Five thousand years, 3000 BCE to 2026; the state in gold, what it replaced or followed and what replaced or followed it in grey.

Before and after

The states the record files it as replacing or following, and those that replaced or followed it - Wikidata's own statements, each read from this state's side.

How it ended, as its article says

Conquered by Moscow, 1485. Read from the article's section “lead” by its grammar; the claim is only that the article says so.

Eventually it lost, decayed, and in 1485, it was annexed by Moscow.

Rulers

Read from the state’s own English article and its rulers’ articles, where Wikidata names no ruler.

6 rulers, 6 with terms dated as terms, covering 1247 – 1490. Median reign 9.5 years. 2 of 5 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”.

Ground held, by year

km² inside its borders as the borders dataset draws them, measured on an equal-area grid; a step series, held between the years the dataset maps.

7,000 km² in 1297, 7,000 km² in 1485; at its largest 7,200 km² in 1347. Cliopatria, CC BY 4.0.

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.

Among all states

Each measure against the states that carry it, never against all of them: a bar is the share of those states below this one.

What led to it, and what came of it

The investigation's own picture: 2 causes the record names and 1 result, 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.
