In 1772 Coimbra, 18-year-old courier Luísa de Jesus collected infants from the city’s anonymous “foundling wheel,” pocketed the state stipend of 600 réis per child, and quietly strangled 33 newborns before anyone noticed. Her arrest, public trial, and execution (she remains the last woman ever put to death in Portugal) forced the kingdom to overhaul its child-protection system. Reforms soon mandated stricter caregiver audits and, by 1783, a nationwide registry for every abandoned baby. What we uncover: The economic loophole that made infant-murder profitable. How lax paperwork and overworked staff masked a year-long killing spree. The public outcry that catalyzed Europe-leading oversight laws. Why Luísa’s case still informs modern discussions of gender, class, and crime. Content notice: This episode discusses infanticide and violence against children.
