## Extracted Topic Notes

- model: The standard scholarly explanation for Spanish conquest is a three-factor model: epidemic disease, divide-and-conquer exploitation of internal conflicts, and European superiority in weapons and technology. Source refs: `video:predictive-history-dnfgcvzrfa@transcript:v1#seg-0008`
- model: Jiang states the Roman message directly: love is a disease or plague on the world because Helen's love causes Troy and Dido's love causes Carthage's war with Rome. Source refs: `video:predictive-history-myturqu7nxu@transcript:v1#seg-0038`
- model: Jiang argues that plague reduced Europe's population because farm life placed people near pigs, rats, garbage, and dense settled communities, while mobile steppe people were less exposed. Source refs: `video:predictive-history-j4htfjwl5d8@transcript:v1#seg-0021`, `video:predictive-history-j4htfjwl5d8@transcript:v1#seg-0022`
- evidence: Jiang identifies the plague as bubonic plague spread by rats, known through DNA evidence, and says it had long been present across the connected world. Source refs: `video:predictive-history-j4htfjwl5d8@transcript:v1#seg-0028`
- diagnosis: Jiang lists three costs of farming: harder work and population pressure, poorer nutrition than hunter-gatherers, and higher disease exposure from dense, dirty settlement with animals and waste. Source refs: `video:predictive-history-jjqf9t59uy0@transcript:v1#seg-0004`, `video:predictive-history-jjqf9t59uy0@transcript:v1#seg-0005`
