On 29 August 1984, two county commissioners in rural Oregon fell mysteriously ill after visiting a religious commune. What followed was the first large-scale bioterrorist attack in American history: 751 people poisoned across ten restaurants as part of a failed election-rigging scheme. This episode also explores the catastrophic opening day of Mainz Cathedral in 1009, when the newly consecrated building caught fire during its own inauguration ceremony; the 1991 murder of Sicilian businessman Libero Grassi, who publicly refused to pay protection money to the Mafia; and Toyotomi Hideyoshi’s 1588 Sword Hunt ordinance, which disarmed Japan’s peasantry and cemented the samurai class system for centuries. Four stories from the same calendar date, each revealing what happens when humans attempt to control the future through planning, power, or sheer bloody-minded refusal to comply. History, as ever, keeps its options open.
