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.

Before it

After it

How it ended, as its article says

Conquered by Prussia, 1866. Read from the article's section “lead” by its grammar; the claim is only that the article says so.

It consisted of several detached territories to the north of Frankfurt, which survived until the state was annexed by Prussia in 1866 following the Austro-Prussian War.

Rulers

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

1 rulers, 1 with terms dated as terms, covering 1847 – 1866. Only 19 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”.

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: 22 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.
