Investigate, rewritten to read: the subject in its own terms, theories judged by their own logic, and every reign with the reason it ended
- Investigate
- Theories
- Rulers and reigns
- Data and accuracy
The Investigate rail now opens on what the subject is — a state's span, origin, body and end; an event's kind and parts; a person's offices, wars and family — before it lists the links, and every link says what it is. Theories are judged condition by condition. A new Succession mode reads every reign with how it ended and where that is known from. Ninety states that flew no flag now show the seal, arms or clan mark their article does.
- The Investigate rail opens on a reading of the subject: a state stood so many years, came after these states and was followed by those, holds this many wars, risings and people, drew this much ground, changed rulers this often, and ended among these events — every name a link, every bar and line a way to move the plot to the years it counts. Click a century to see what the atlas holds in it.
- Every link says what it is. A predecessor state, a battle in a war or a ruler's father used to read as a “long-term cause · weak”; it now reads as the relation the record made, and says it is not a cause. Long lists are grouped by what the links are — “Took part in · 36”, “Family · 9” — with the largest group open.
- Theories are judged by their own logic, condition by condition: which of the conditions a theory names held here, which were absent, and which could not be measured, with the rows behind each. Theories that come close — some conditions held, not enough — are shown with what was missing. Whether the authors wrote about the case is a footnote, never the verdict.
- What says nothing is out of the way: measurements that could not run, the names in the article and the links set aside are behind a click, with their counts on the label.
- A Succession mode in Investigate, for any state with a line of rulers: every reign with its dates, the ruler's age, how the reign ended — died in office, killed, executed, in battle, left alive, deposed as coded — and the source of that reason: Wikidata's manner of death, Kokkonen & Sundell's coding for 27 European monarchies, or the dates alone.
- Who followed whom: for every handover, whether the successor was the predecessor's child, sibling, spouse or other recorded kin. Where nothing is recorded it says so, never "unrelated".
- The numbers beside the list: median reign and its spread, a survival curve against the atlas as a whole, age at accession, interregna and rival claimants, the risings beside a handover by name, and the same by century.
- Download the reign table as CSV, with every ending and its source.
- Ninety states that flew no flag — the Mongols, the Ming, the Sasanians, the Achaemenids — now show the symbol their article does: a seal, a standard, a coat of arms, a clan mark or a coin, named as what it is. 1,098 of the atlas's 1,522 states now carry a symbol.
