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.

Rulers

The line of President of the United States - the office this state names as its head of state.

57 rulers, 46 with terms dated as terms, covering 1789 – 2025. Median reign 4 years. 6 of 47 handovers irregular - a killing, a deposition, a rival claimant, a rising or a coup beside it. The violent-handover count is withheld: power changed hands so often that any rising falls beside one (exposure 0.92, limit 0.6). A blank in the last column means no kin on record, which is coverage, never “unrelated”.

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: 73 causes the record names and 0 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.
