Add 1350 checkpoint and Great Khanate internal fractures

1350 Black Death consequences:
- Song: moderate demographic hit but severe political "Mandate" crisis
- SE Asia: catastrophic depopulation, Chinese settlers fill vacuum
- Great Khanate: economic crisis → disastrous policies → northern Silk Road dies
- Germany: independence movement triggered by tribute demands
- Ilkhanate: survives, gains trade monopoly as routes shift south
- Italy: becomes Europe's new eastern trade gateway

Great Khanate internal fractures (new section):
- Post-plague economic transformation: trade empire → serfdom empire
- Rus identity fragments into 5+ distinct groups
- Novgorod divergence: economic reorientation toward Germany, religious split
- Religious schism: Volga Mongolized Orthodoxy vs Constantinople Orthodoxy
- Agricultural pivot: Mongol landlords + Slavic serfs in Ukraine/Hungary

+### Post-Black Death Economic Transformation (~1350s-1400s)
+- Black Death devastates Rus urban population → economic crisis
+- Great Khanate responds with: increased tribute on vassals, increased Silk Road transit fees, currency inflation
+- **Consequence**: merchants abandon northern Silk Road route for Chagatai/Ilkhanate southern routes
+- Northern Silk Road effectively dies → Novgorod's economic basis collapses
+- **Forced agricultural pivot**: Mongol nobility become landed gentry/estate owners in Ukraine and Hungarian Plain (best farmland in Europe)
+- Rus and other subject peoples forcibly resettled as agricultural serfs on these estates
+- Empire transforms from trade-military state to **agricultural serfdom empire**
+- Parallels historical Russian serfdom but arrived at through different path
+- By V3 era: serfdom is the core obstacle to industrialization (same as historical Russia)
+
+### Internal Fractures (V3 Event Chain Material)
+
+#### Rus Identity Fragmentation
+The "Rus" people never unify into a single identity (no Moscow to force unification). By V3 era, at least 5 distinct groups:
+
+1. **Novgorod Rus** — Merchant/republican tradition, Western-oriented (Hanseatic ties), traditional Constantinople Orthodoxy. Post-trade-collapse: economically reorients toward Germany, culturally diverges from Great Khanate core. Strongest separatist potential.
+2. **Kiev-Dnieper Rus** — Around Great Khanate's administrative centers. Most Mongolized, accepts Volga Orthodox sect. Urban, bureaucratic.
+3. **Northeast Forest Rus** (Moscow, Vladimir) — Agricultural, isolated, most "Old Rus" traditions preserved. Under direct Mongol rule but less culturally penetrated than Kiev.
+4. **Ukrainian Steppe Rus** — Newly resettled serf communities on Mongol-owned estates. Mixed origins (drawn from across the empire). Developing unique identity from shared oppression.
+5. **Hungarian Rus** — Serfs forcibly relocated to Hungarian Plain. Mixed with Mongol, Kipchak, remnant Magyar populations. Completely distinct identity forming.
+
+#### Religious Schism: Volga Orthodoxy vs. Constantinople Orthodoxy
+- Great Khan baptized ~1325-1350, develops Mongolized Orthodox sect (Tengri/shamanic elements fused with Orthodox theology)
+- Independent patriarchate on the Volga, rejects Constantinople's primacy
+- Novgorod and some western Rus communities **refuse** Volga Orthodoxy, align with Constantinople
+- Religious divide becomes ethnic/political divide: "true Orthodoxy" vs. "Mongol heresy"
+- Parallels: historical Ukrainian Greek Catholic vs. Russian Orthodox split, but earlier and more radical
+
+#### Other V3 Tensions
+- **Mongol-Slavic ethnic tension**: Mongol military aristocracy vs. Slavic serf majority
+- **Serfdom reform pressure**: Industrial Song's example creates pressure for modernization
+- **Novgorod autonomy movement**: economic reorientation toward Germany, demands for self-governance
+- **Polish independence movement**: Catholic/Western identity under Orthodox Mongol suzerainty
+- **Hungarian integration problems**: multi-ethnic agricultural zone with unresolved Magyar minority
+- Combined: vanilla V3's Russia + Austria + Ottoman problem sets, all in one country
+
 ### Key Characteristics for V3
-- Enormous territory, relatively low GDP
-- Multi-ethnic stability problems (similar to vanilla Austria/Ottoman)
-- Industrialization reform as main storyline (technology dependent on Song imports)
-- Relationship with Song: trade dependence vs. geopolitical rivalry
-- Internal Mongol identity vs. Slavic identity conflict
+- Enormous territory, relatively low GDP (agricultural serfdom economy)
+- Multi-ethnic stability problems (worse than vanilla Austria/Ottoman — 5+ Rus sub-identities + Mongol elite + Polish/Lithuanian/Baltic vassals)
+- Industrialization reform as main storyline (serfdom must be abolished first)
+- Lost position as Silk Road transit power → economically isolated, dependent on grain exports
+- Relationship with Song: former trade partner, now economic periphery
+- Internal Mongol identity vs. Slavic identity conflict accelerating

+## 1350 Checkpoint: Black Death and its Consequences
+
+### Black Death Transmission and Impact (~1346-1360)
+Plague travels via Silk Road trade routes. More active trade in this timeline means potentially faster spread.
+
+| Region | Impact | Notes |
+|---|---|---|
+| Great Khanate (Rus cities) | Severe (30-50%) | Urban populations devastated |
+| Western Europe | Severe (30-60%) | Similar to our timeline |
+| Ilkhanate / Middle East | Severe (30-40%) | Cairo hit especially hard |
+| Song Dynasty | Moderate (10-20%) | Better sanitation, historical plague resistance. But political impact severe: "loss of Mandate" narrative |
+| Southeast Asia | **Catastrophic (50-80%)** | No previous exposure. Song maritime trade carries plague to colonial ports. New World-style demographic collapse. Chinese settlers fill vacuum. |
+| Mongol Khanate | Minimal | Population too sparse for epidemic transmission |
+| Steppe/pastoral zones | Low-moderate | Low density provides natural social distancing |
+
+### Key Consequences by Region
+
+**Song Dynasty**: Plague + "Mandate of Heaven" crisis. Population decline temporarily eases North-South economic tension (fewer workers → higher wages in south). But land consolidation already completed by landlord class — structural problems not resolved, merely postponed. Northern military officials use crisis to expand autonomy. Surface unity, deepening internal fracture.
+
+**Great Khanate**: Economic crisis → disastrous policy responses (tribute hikes, transit fee increases, currency inflation) → northern Silk Road dies → Novgorod collapses economically → forced agricultural pivot to Ukraine/Hungary → serfdom deepens → German vassals break away. See "Post-Black Death Economic Transformation" section above.
+
+**Greater Germany**: Black Death + Great Khanate tribute demands = final trigger for independence movement (~1350-1380). Hanseatic cities lead formal break from Mongol vassalage. Great Khanate too weakened to enforce compliance militarily.
+
+**Ilkhanate**: Hit hard but survives. Trade revenue temporarily drops but infrastructure intact — recovers as plague passes. Egypt's governor uses chaos to expand autonomy → semi-independent by ~1375. Ilkhanate remains wealthiest successor state due to trade monopoly position.
+
+**Southeast Asia**: Demographic catastrophe transforms the region. Song colonial presence shifts from trading posts to territorial control as local populations collapse. By ~1400, coastal SE Asia increasingly Chinese-settled.
+
+**Bohemia**: Relatively protected by mountain geography. Stable, wealthy (silver mines). Positions itself as key ally of emerging independent Germany.
+
+**Kalmar Union**: Scandinavian kingdoms severely weakened (Norway especially). Accelerates union formation — possibly 1360s-1370s instead of historical 1397.
+
+**Italy**: Hit hard by plague (historical). Venice and Genoa trade networks disrupted but recover. As trade shifts to southern Silk Road routes, Italian city-states become **Europe's new gateway** to Eastern goods via Mediterranean → Ilkhanate connection, replacing collapsed Novgorod route.
+
+**Trade Route Revolution**: Northern Silk Road (Great Khanate) effectively dies. Southern routes (Chagatai → Ilkhanate → Mediterranean) become dominant. Sea routes grow. Winners: Ilkhanate, Italian city-states, Chagatai. Losers: Great Khanate, Novgorod.

 1. **1300-1500 era**: Each region's evolution through late medieval period
 2. **Italy post-1300**: Renaissance? Different city-state dynamics? Unification pressure?
