Why Rome actually fell: plagues, slavery, & ice age — Kyle Harper

800 years before the Black Death, the very same bacteria ravaged Rome, killing 60%+ of the population in many areas. Also, back-to-back volcanic eruptions caused a mini Ice Age, leaving Rome devastated by famine and disease. I chatted with historian Kyle Harper about this and much else: * Rome as a massive slave society * Why humans are more disease-prone than other animals * How agriculture made us physically smaller (Caesar at 5'5" was considered tall) 𝐄𝐏𝐈𝐒𝐎𝐃𝐄 𝐋𝐈𝐍𝐊𝐒 * Transcript: https://www.dwarkesh.com/p/kyle-harper * Apple Podcasts: https://podcasts.apple.com/us/podcast/dwarkesh-podcast/id1516093381?i=1000704767817 * Spotify: https://open.spotify.com/episode/5LhE123eOtQoOm0IPusEiT?si=4d7d8b25374a4f92 𝐒𝐏𝐎𝐍𝐒𝐎𝐑𝐒 * WorkOS makes it easy to become enterprise-ready.
