Map: Duchy of Saxe-Weimar-Eisenach in 1828, its borders in gold among its neighbours
Duchy of Saxe-Weimar-Eisenach in 1828, when it held the most ground the borders dataset draws for it: 4,100 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.

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

How it ended, as its article says

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

It was succeeded by the Free State of Saxe-Weimar-Eisenach, which was merged into the new State of Thuringia two years later.

What led to it, and what came of it

The investigation's own picture: 5 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.

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.
