Map: Congress Poland in 1830, its borders in gold among its neighbours
Congress Poland in 1830, when it held the most ground the borders dataset draws for it: 131,400 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.

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: 8 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.

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.
