Map: Duchy of Brunswick in 1820, its borders in gold among its neighbours
Duchy of Brunswick in 1820, when it held the most ground the borders dataset draws for it: 4,800 km². Its neighbours wear their tints, as on the atlas's own map. Borders from Cliopatria (CC BY 4.0), coast and rivers from Natural Earth, cities from Reba, Reitsma & Seto 2016 (CC BY 4.0), each city under the name it bore that year.

How it ended, as its article says

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

It was disestablished after the end of World War I, its territory incorporated into the Weimar Republic as the Free State of Brunswick.

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 1813 – 1815. Only 2 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”.

Ground held, by year

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.

  • The most ground it held4,800 km²

    held more ground at its peak than 9% of 1,465 states with a border in Cliopatria.

  • Wars recorded per centurynone

    had more wars on record per century than 44% of 3,187 states, counting the wars the atlas hosts under each.

  • Rulers on record1

    has more rulers on record than 13% of 1,968 states with a line of rulers.

What led to it, and what came of it

The investigation's own picture: 4 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.

Theories that apply to its ending

Of 3 theories of why states fall, 1 has every condition present at this ending; each is applied by its own logic, condition by condition, and whether its authors named this case is a footnote.

  • Dynastic cycle and the decay of group feeling

    Ibn Khaldun 1377 · Turchin & Nefedov 2009

    Applies by its own logic: the condition it names held here, and this is the kind of outcome it predicts — adverse regime change or the state's ending.
