Mongol conquests (1215): Zhongdu falls — Section 948: Zhongdu falls
Reading 948 of Mongol conquests uses “Zhongdu falls” and figure 1206 as a checkable baseline. mongol-conquests · beat 1 · Ain Jalut, Japan, stubborn Goryeo then submission. In 1215, Mongol conquests is “Zhongdu falls” at scale 1206. No nation league table. A split diagram after the 1260s -- the honest map.
Deaths are among the least certain in this atlas: published scholarly ranges often sit around 20-40 million across the thirteenth century, with some older figures higher and many local studies lower. Siege massacres (Baghdad 1258, Zhongdu, Nishapur in the chronicles) sit beside famine and displacement. Treat every total as a band, not a census.
The same empire that destroyed cities also ran relay posts (yam), protected some trade, and moved artisans and astronomers across Eurasia -- the "Pax Mongolica" of later textbooks. English memory arrives through Travels of Marco Polo, school maps of a pink-brown blob, and a thin film canon. Korean memory is more specific: the 1231-59 Goryeo wars and the forced 1274/1281 expeditions toward Japan.
Steppe unification, city sieges, and a Eurasian afterlife The Mongol wars were a technology of mobility and terror that became, in the successor khanates, a system of tax, post and pluralism -- at a demographic price still counted in ranges. Chinggis's early wars were against steppe rivals, then Western Xia and Jin. The 1215 fall of Zhongdu (Beijing) is an early named urban catastrophe in the Chinese record.
The timeline keeps year, place, and what moved. If “Zhongdu falls” is the movement, the figure is 1206 and the year is 1215. In 1215, Mongol conquests is “Zhongdu falls” at scale 1206. No nation league table. 12061215

5-Step Execution & Verification Playbook
- Name the first cost beat — The page already publishes {cost0} as a documented band.
- Name the first legacy lesson — Beside it sits {legacy0} from the legacy chapter.
- Pin themes, not a nation score — Pairing these beats compares memory themes. This atlas never ranks countries or peoples as teams.
- Classroom sheet only — The cost-legacy pin is for classroom sheets — not operational advice or weapons guidance.
- Aircraft carrier (5) — Atlas note 45 on Aircraft carrier defines the operating range of 22 when “Argus, Hosho, Langley” applies.
Myth vs. Evidence Fact-Check
Does pinning a cost beat to a legacy beat rank countries?
No. The pin only pairs two beats already on this topic. Scores browse themes. This atlas never ranks nations or peoples as teams.
Which cost bands can I pin on this page?
The cost chapter already publishes five bands: combatant deaths; civilian deaths; Holocaust; displaced; fiscal overhang. The 70-85 million death range is a scholarly band, not a census.
Which legacy lessons sit next to those bands?
Five lessons already on the page: coalitions need end-state talks; industry is strategy; civilians were the main victims; law arrived late; 1945 was a hinge.
Is this operational advice?
No. Documented ranges and memory notes only. Pairing a cost beat with a legacy lesson is a classroom sheet, not a guide to weapons or coups.
