Topic	Kind	Taught by	Status	Detail
French Revolution	Event	AP World History: Modern, CBSE Class XI — Themes in World History (NCERT), 歴史総合 (Rekishi Sougou — History Comprehensive), 普通高中历史课程标准 / 中外历史纲要 (General Senior Secondary History Curriculum Standard)	In the catalogue	The French Revolution (event, 1789 CE – 1799 CE) Related polities: `polity-france` (on the map 1279 CE – 2010 CE) Re-confirmed 2026-08-21 as genuinely absent from events.json — the only French Revolutionary-era entry today is event-french-campaign-egypt-syria (Napoleon's Egypt campaign), which is tangential, not the Revolution itself. polity-france spans 1279-2010 and is present at 1783, 1800 and 1815, so the registry is ready whenever an event is authored. The strongest single row on the table: all four surveyed syllabi teach it. MERGED 2026-08-22: the event now exists in events.json (TODO.md #23 Lane A), so this topic is no longer a gap.
Safavid Persia	Event	AP World History: Modern, CBSE Class XI — Themes in World History (NCERT)	In the catalogue	Rise of the Safavid Empire (event, 1501 CE – 1555 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 1500 CE): polity-safavid-empire. The event still exists and is explorable — this only says the map at that one year does not show every side of it. Related polities: `polity-safavid-empire` (on the map 1530 CE – 1715 CE) polity-safavid-empire (1530-1715) is registry-ready; no dedicated event exists. MERGED 2026-08-22: the event now exists in events.json (TODO.md #23 Lane A), so this topic is no longer a gap.
Srivijaya	Event	AP World History: Modern	In the catalogue	Indian Ocean monsoon trade (event, 100 BCE – 1500 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 100 BCE): polity-satavahanihara, polity-axum, polity-abbasid-caliphate, polity-muscat, polity-chola-state, polity-srivijaya-empire, polity-song-empire. The event still exists and is explorable — this only says the map at that one year does not show every side of it. The Indian Ocean before Europe (guided story) Related polities: `polity-srivijaya-empire` (on the map 800 CE – 1400 CE) polity-srivijaya-empire (800-1400) is already a participant in event-indian-ocean-trade and that event is this catalogue's primary event for the-indian-ocean-before-europe. This is the one Lane A row that turns out to already be covered, through an event the harvest pipeline never proposed under this name — found by cross-referencing participant lists, not by keyword-matching event titles (which would have missed it, and separately would have produced false positives elsewhere — see the 'ethiopia'/'zimbabwe' false-match note in the derivation script's own comments).
Khmer Empire / Angkor	Event	AP World History: Modern	In the catalogue	Spread of Buddhism (event, 250 BCE – 1200 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 300 BCE): polity-sinhalese-kingdoms, polity-kushan-empire, polity-silla, polity-tang-empire, polity-japan, polity-tibetan-empire, polity-khmer-empire. The event still exists and is explorable — this only says the map at that one year does not show every side of it. Related polities: `polity-khmer-empire` (on the map 900 CE – 1400 CE) polity-khmer-empire is a participant in event-spread-of-buddhism (-250..1200). That event is ABOUT Buddhism's diffusion, not Angkor's own political history, so this is coverage of the topic's religious dimension only — the honest caveat the page prints rather than a claim that Angkor's rise and monument-building are covered.
Great Zimbabwe	Event	AP World History: Modern	In the catalogue	Swahili coast Indian Ocean trade (event, 800 CE – 1500 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 800 CE): polity-great-zimbabwe, polity-mwenemutapa, polity-madagascar, polity-yemen, polity-gujarat. The event still exists and is explorable — this only says the map at that one year does not show every side of it. Related polities: `polity-great-zimbabwe` (on the map 1000 CE – 1400 CE) polity-great-zimbabwe (not polity-zimbabwe, the modern state — a distinct id, checked explicitly because a naive keyword search on 'zimbabwe' also matches four unrelated modern events) is a participant in event-swahili-coast-indian-ocean-trade.
Mali Empire	Event	AP World History: Modern	In the catalogue	Spread of Islam (event, 622 CE – 1500 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 600 CE): polity-umayyad-caliphate, polity-abbasid-caliphate, polity-ghaznavid-emirate, polity-kanem, polity-mali, polity-sultanate-of-delhi, polity-aceh, polity-malacca. The event still exists and is explorable — this only says the map at that one year does not show every side of it. Trans-Saharan gold and salt trade (event, 700 CE – 1600 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 700 CE): polity-mali, polity-songhai, polity-morocco, polity-mamluke-sultanate, polity-berbers, polity-tuaregs. The event still exists and is explorable — this only says the map at that one year does not show every side of it. Related polities: `polity-mali` (on the map 1000 CE – 2010 CE) READY, correcting the original review's wrong 'no registry entry' finding (it looked like a substring search that matched 'Somaliland'/'Fourche Maline' and concluded wrongly). polity-mali (1000-2010) is a participant in two existing events; West Africa generally is well covered (empire-of-ghana, songhai, bornu-kanem, hausa-states, oyo, benin all exist).
Silk Road exchange networks	Event	AP World History: Modern draft	In the catalogue	Silk Road exchange (event, 130 BCE – 1450 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 100 BCE): polity-roman-empire, polity-parthian-empire, polity-tang-empire, polity-abbasid-caliphate. The event still exists and is explorable — this only says the map at that one year does not show every side of it. The Silk Road was a relay (guided story) DRAFT, weaker attribution than the todo23 rows above: the agent's own judgment that trans-Eurasian trade networks are standard AP World Modern content (Units 1-2), not verified against the CBSE/MEXT/PRC documents fetched for #23. The COVERAGE claim itself is measured (event-silk-road-exchange and the-silk-road-was-a-relay both exist and are the catalogue's actual entries for this subject); only the syllabus count is a draft guess.
Indian Ocean trade network before European arrival	Event	AP World History: Modern draft	In the catalogue	Indian Ocean monsoon trade (event, 100 BCE – 1500 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 100 BCE): polity-satavahanihara, polity-axum, polity-abbasid-caliphate, polity-muscat, polity-chola-state, polity-srivijaya-empire, polity-song-empire. The event still exists and is explorable — this only says the map at that one year does not show every side of it. The Indian Ocean before Europe (guided story) DRAFT syllabus attribution, same caveat as silk-road-exchange above. Coverage links are the same event/story already cited for the Srivijaya row — this is the broader trade-network framing of the same catalogue entry, kept as a separate topic because a teacher may search for either name.
The Mongol conquests	Event	AP World History: Modern draft	In the catalogue	Mongol conquest of China (event, 1205 CE – 1279 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 1200 CE): polity-great-khanate. The event still exists and is explorable — this only says the map at that one year does not show every side of it. The Mongol century (guided story) DRAFT syllabus attribution (standard AP World Unit 1 content, not re-verified against the other three syllabi).
1492: the encounter of the Americas and Afro-Eurasia	Event	AP World History: Modern draft	In the catalogue	Inca imperial expansion (event, 1438 CE – 1533 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 1400 CE): polity-inca-empire. The event still exists and is explorable — this only says the map at that one year does not show every side of it. 1492, from both sides (guided story) DRAFT syllabus attribution. The linked event and story are named for the Inca side of the encounter specifically (see fourteen-ninety-two-from-both-sides), not the whole hemispheric 'Columbian Exchange' concept — the page should not claim more than that catalogue entry actually argues.
Abolition of the Atlantic slave trade	Event	AP World History: Modern draft	In the catalogue	The abolition of slavery (event, 1791 CE – 1888 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 1783 CE): polity-haiti, polity-united-kingdom-of-great-britain-and-ireland, polity-kingdom-of-brazil, polity-sultinate-of-zanzibar. The event still exists and is explorable — this only says the map at that one year does not show every side of it. The revolution nobody would name (guided story) DRAFT syllabus attribution (standard AP World Unit 5 content, not re-verified against the other three syllabi).
The Scramble for Africa / New Imperialism	Event	AP World History: Modern draft	In the catalogue	The Scramble for Africa (event, 1881 CE – 1914 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 1880 CE): polity-german-empire, polity-abyssinia, polity-belgian-congo. The event still exists and is explorable — this only says the map at that one year does not show every side of it. DRAFT syllabus attribution. No dedicated story exists for this event today, only the event itself.
The collapse and partition of the Ottoman Empire	Event	AP World History: Modern draft	In the catalogue	The collapse and partition of the Ottoman Empire (event, 1916 CE – 1923 CE) Not every participant is drawn on the snapshot nearest this event's own start year (checked against 1914 CE): polity-ottoman-sultanate, polity-hejaz, polity-hail, polity-mandatory-palestine-gb, polity-mesopotamia-gb, polity-syria-france. The event still exists and is explorable — this only says the map at that one year does not show every side of it. 1919 (guided story) DRAFT syllabus attribution (standard AP World Unit 7 content, not re-verified against the other three syllabi).

Topic	Kind	Taught by	Status	Detail
Haitian Revolution	Event	AP World History: Modern, 普通高中历史课程标准 / 中外历史纲要 (General Senior Secondary History Curriculum Standard)	On the map, not yet written up	Related polities: `polity-haiti` (on the map 1715 CE – 2010 CE) polity-haiti (1715-2010) is registry-ready. Haiti appears as one of ten participants in the broader event-abolition-of-slavery (1791-1888), but that event's subject is abolition across multiple empires, not the Haitian Revolution as its own dated struggle — too tangential to count as coverage of this specific topic, the same standard applied to the French campaign above.
Latin American independence	Event	AP World History: Modern, 普通高中历史课程标准 / 中外历史纲要 (General Senior Secondary History Curriculum Standard)	On the map, not yet written up	Related polities: `polity-vice-royalty-of-new-spain` (on the map 1530 CE – 1815 CE), `polity-spain` (on the map 1530 CE – 2010 CE), `polity-portugal` (on the map 1200 CE – 2010 CE), `polity-mexico` (on the map 1880 CE – 2010 CE), `polity-argentina` (on the map 1880 CE – 2010 CE), `polity-bolivia` (on the map 1880 CE – 2010 CE), `polity-brazil` (on the map 1914 CE – 2010 CE) NOT registry-ready at the wars' own dates (re-verified 2026-08-21): polity-mexico, polity-argentina and polity-bolivia all have firstSeen 1880, absent from snapshot_1815, and the independence wars run 1808-1826 across a 1800->1815->1880 gap in the snapshots. What IS drawable at 1815 is the COLLAPSE of the viceroyalties (polity-spain, polity-portugal, polity-vice-royalty-of-new-spain, which ends exactly at 1815) — a different event from the founding of the republics, and an editorial choice the owner has not made. All seven listed polities are in the registry, so the topic is map-only regardless of which framing is picked.
Mesopotamia — the first cities	Event	AP World History: Modern, CBSE Class XI — Themes in World History (NCERT)	On the map, not yet written up	Related polities: `polity-city-states` (on the map 3000 BCE – 2000 BCE), `polity-elam` (on the map 3000 BCE – 700 BCE) PARTIAL, not ready as originally hoped: snapshot_-3000 has a generic polity-city-states and polity-elam (both -3000..-2000/-3000..-700), enough for participants, but there is no Sumer, Uruk or Akkad in the registry at all, and Babylonia/Assyria do not appear until -1500 — thousands of years after 'first cities'. Writing the event against what exists, or adding three registry entries first, is the owner's call (TODO.md #23).
Solomonic Ethiopia	Event	AP World History: Modern	On the map, not yet written up	Related polities: `polity-ethiopian-highland-peoples` (on the map only at 700 CE) polity-ethiopian-highland-peoples has firstSeen == lastSeen == 700 — one of the 52% of polities that appear in exactly one snapshot (AGENTS.md). It is registry-ready but appears in only that single snapshot, so map exploration of this topic is limited to the year 700 specifically, not a range. (Its label has a stray capital I, 'Ethiopian HIghland Peoples' — spotted in passing per TODO.md #23/#10, unrelated to this page and out of scope here.) The modern-Ethiopia events (event-scramble-for-africa, event-smallpox-vaccination-and-eradication, event-tigray-war) all use the DIFFERENT id polity-ethiopia and are a different, much later polity — not linked here, the same false-match trap as Great Zimbabwe above.

Topic	Kind	Taught by	Status	Detail
Majapahit	Event	AP World History: Modern	Not here yet	No registry entry at all (checked directly against polities.json, 2026-08-22) — registry work would have to come before any event, per TODO.md #23's row 13.
Cahokia	Event	AP World History: Modern	Not here yet	No registry entry at all (checked directly against polities.json, 2026-08-22) — registry work would have to come before any event, per TODO.md #23's row 14.
Feudal Europe and the three orders	Story	not scored against the four syllabi	Not here yet	Not event-shaped at all (TODO.md #23): a social structure has no start, no end and no participant polities, which events.json requires of every entry. Story-shaped, not yet built. No syllabus convergence count exists for this row — it was never scored against the four documents, so 'syllabi' is deliberately empty rather than guessed.
Displacing indigenous peoples	Story	not scored against the four syllabi	Not here yet	Spans centuries and two hemispheres; forcing it into one event would flatten hundreds of distinct histories into a single participant list (TODO.md #23). #13's 1,305-feature indigenous-territories layer already ships the geography this story would need — only the narration is missing. No syllabus convergence count scored.
