Brief summary (#TLDR): The Black Death (BD) had a significant long-term impact on Germany’s political development. Hard-hit areas introduced proto-democratic institutions; sustained experiences with participative government later helped reject antidemocratic & illiberal parties.
Long overview (starting here): In 1347, Europe was hit by a pandemic that killed 30–60% of its population: the BD. It had a major impact on medieval society which was based on feudalism/serfdom. Yet the BD’s impact varied greatly across space, leading to divergence in its impact.
