How kings lost their thrones, and a round of data fixes
- Rulers and reigns
- Cities and places
- Data and accuracy
Hand-coded depositions for 27 European monarchies, counts of each state’s titled elite, and fixes from a review of the data.
- How 27 European monarchies lost their kings, 1000–1799: 723 reigns coded by hand by Kokkonen, Krishnarajan, Møller and Sundell, with who was deposed or killed and by whom, civil wars, and parliaments per century. It is shown beside the atlas’s own line of rulers, with how often the two agree.
- What the record holds of each state’s elite: per half-century, how many of its citizens Wikidata records, how many held a noble title, and how many held one of its offices. A half-century resting on fewer than 20 people is marked unmeasured rather than drawn as small.
- Fixed: NOAA’s hazard catalogue had been read only in part, so the atlas held no NOAA earthquake between 1811 and 1999. It now holds all 10,726 eruptions, earthquakes and tsunamis.
- Fixed: a state’s allies and vassals were counted as its own territory; the Papal States had read 7.4 million km² in 1609.
- Lines of rulers now keep every term a ruler held, so Henry VI of England no longer loses his first reign, and a generic title such as “Prince-Elector” no longer turns other states’ rulers into a line.
- Coups are now filed as regime changes, from the coup of 18 Brumaire to Myanmar in 2021; failed attempts and revolutions stay under unrest.
- Present-day states now run to the present, so France hosts events after 2000, and a state with no recorded end says so. An event’s host state is found by the border in that year before any nearest-state guess, which is now capped at 1,500 km.
- Fixed: a sentence dating something to “612 BC” was read as 612 CE.
