Legacy Podcast — Great Environmental Shocks in History: Before the Plague | Episode 3
Hosts: Afua Hirsch & Peter Frankopan
Date: March 19, 2026

Episode Overview

In this episode of Legacy, historians Afua Hirsch and Peter Frankopan dive into environmental crises before the Black Death, with a particular focus on the catastrophic effects of climate shocks and bovine pestilence in the early 1300s. The discussion unpacks how environmental disasters—especially those affecting cattle—contributed to famine, economic instability, and long-term societal consequences across Eurasia and North Africa. Central to their analysis: the “Great Famine” and its role in priming Europe for the devastation of the Black Death.

Key Discussion Points & Insights

1. The Allure and Limits of Medieval History

• Afua reflects on her ambivalence about the Middle Ages, explaining her discomfort with the "glamorization of the Crusades," and her desire for a more nuanced, global view of the period.
  • "It just didn't sit well on multiple levels. And I think maybe that put me off an area which actually I think does have a lot to offer me." — Afua Hirsch (01:00)
• Peter underscores the era’s global connections: integrating Mongol history and the influence of Africa and the Islamic world.

2. Environment as a Force in History

• The global Little Ice Age’s first signs: In the late 1200s, paleoclimate data and historical records (esp. from East Asia) reveal crop failures, cold snaps, and food shortages.
  • "At the end of the 1270s... we hear about crop failures. We hear about late frosts and unusual snowfalls." — Peter Frankopan (06:54)
• Asian societies—particularly China’s Yuan dynasty—interpreted environmental hardships as evidence of lost “Mandate of Heaven,” triggering political and social responses.
  • "A good person and a good leader is blessed with good environmental conditions, and a bad one faces flooding, epidemics, disaster, shortages." — Peter Frankopan (08:30)

3. Cascading Climate Shocks Across Eurasia

• 1308: Catastrophic snowstorms on the Mongolian steppe prompt mass livestock die-offs and trigger migrations, causing famine and social collapse in affected areas.
• Series of freak storms in Syria and Mesopotamia (1319–20) devastate homes and orchards, reducing incomes, raising social tension, and escalating hardship among the rural and urban poor.
  • "Orchards... it takes crops like olive trees decades to mature. You can't just start again for the next harvest." — Afua Hirsch (13:13)
• These patterns reverberate: loss leads to scarcity, scarcity leads to price hikes, unrest, and scapegoating.

4. Early Urban Resilience and (Limited) Adaptation

• Medieval European cities respond to repeated droughts and famines by investing in ports, deeper wells, and water infrastructure to “ride out” crises.
  • "Cities start to invest in deeper wells or in water infrastructure to make sure that they can get through drought conditions and so on." — Peter Frankopan (15:01)

5. The Great Famine & the Importance of Cattle

• Early 1300s: After unprecedented expansion and agricultural intensification, Europe’s prosperity rests on delicate supply chains and cattle.
  • "Cattle were the engine of this world for arable farming. They were absolutely the tractors of their day." — Afua Hirsch (23:43)
• Harvest failures pile up (1315-1317):
  • Grain yields drop to 10% of normal by 1317 (28:31–29:19).
  • Not only does hunger rise, but bovine pestilence—likely rinderpest—ravages cattle herds from 1315 onward.
  • "We think somewhere between 60 to 70% of all cattle die [in England and Wales]." — Peter Frankopan (31:13)
• Effects spiral: loss of cattle undermines plowing (and thus grain production), protein intake, labor productivity, and agricultural sustainability.
• "Oxen were central to plowing these very heavy soils in northern Europe... now that’s requiring humans to do that work." — Afua Hirsch (32:20)

6. Social Consequences: Scapegoats and Persecution

• Famine and disease prompt “moral panic,” with Jews, lepers, and other minorities being blamed and targeted for disaster:
  • "There's a really horrible dark tradition in Europe...where when anything went wrong, they would turn to the visible Jewish minority and blame them for everything." — Afua Hirsch (34:55)
• State and church engage in both condemnation and complicity, with mass arrests and expulsions (35:00–36:09).
• Research shows pogroms statistically correlate with temperature declines and hardship.

7. Political & Economic Legacies

• Governments intervene, banning grain exports to keep food local and imposing trade restrictions (39:20).
• Eventual “normalization” of blaming visible minorities, setting patterns for future crises (hinted connections to witch-hunts in later centuries).

8. Biological Legacies and “Cohort Scarring”

• Malnutrition from the Great Famine (especially loss of protein) produces generational health effects—compromised immunity, stunted growth—that leave populations especially vulnerable to the Black Death.
  • "Children in utero or in early childhood in this period... experience such specific protein energy deficiency... that this creates a higher lifetime risk to infection and earlier mortality too." — Peter Frankopan (41:16)
• Lasting poverty and dietary deficiencies linger into the 1320s and 1330s, especially among the poor.

9. Why Is This Forgotten?

• The show discusses why the Great Famine, despite its scale and effects, is overshadowed by the more dramatic narrative of the Black Death:
  • “I think the Black Death is just so the superstar of the medieval era. It kind of sucks up all the limelight, doesn’t it?” — Afua Hirsch (45:15)
• Peter explains the complexity of researching and narrating such diffuse, multi-causal crises versus the hook of a “villain” or a singular event.

10. Final Reflections: Relevance for Today

• Patterns of scapegoating, economic contraction, and biological legacy have deep parallels in modern responses to climate shocks and pandemics.
• “Instead of really thinking about how we could strategically get ahead of the shocks that are coming, we tend to turn to populism or xenophobia…” — Afua Hirsch (39:20)

Notable Quotes & Memorable Moments

• "A man's oxen are his livelihood... Anyone who loses their cow loses their living." — Peter Frankopan, citing medieval sources (24:57)
• “Protein shortage, death.” — Peter Frankopan, summarizing cascading effects of famine and cattle loss (34:11)
• “These early experiences were actually a prelude to something much more serious that was on the horizon.” — Afua Hirsch foreshadowing the Black Death (16:35)
• “It strikes me as so ironic that you're producing essentially a generation with compromised immunity just when you need a generation with better immunity than ever because of the pestilence that's coming.” — Afua Hirsch (42:26)
• “The Black Death is the superstar of the Middle Ages, Aphra. And you can't beat the superstar, right?” — Peter Frankopan (46:49)
• “This is a message that will probably resonate quite easily with our listeners... we’re now back in an era where the value of protein has become almost a social signifier.” — Afua Hirsch (25:54)
