The arrival of the great plague in 1656 presented the Republic of Genoa with a catastrophic challenge, testing the limits of its governance and societal resilience. Originating in Sardinia, the pestilence reached the bustling port city despite initial containment efforts, swiftly overwhelming its public health infrastructure.
The Genoese Magistrato di Sanità (Health Magistracy) faced a difficult choice between enforcing a strict, economically crippling quarantine and maintaining the city’s vital maritime commerce. Initially, authorities hesitated, implementing measures that were perceived as insufficient and delayed. Unlike the more rigid cordons sanitaires established by other Italian states, Genoa’s response was hampered by a desire to protect its trade interests, a strategy that ultimately proved disastrous. This indecision allowed the contagion to establish an unbreakable foothold within the densely populated urban center.
By the summer of 1657, the consequences of this strategic miscalculation were horrifyingly clear. The plague scythed through the populace, claiming an estimated 60,000 lives—more than half of the city’s population. Entire districts were depopulated, and the Republic’s economic engine ground to a halt. The sheer scale of mortality crippled the Genoese state for generations, diminishing its demographic strength and weakening its position as a dominant Mediterranean power. The event stands as a stark testament to the fatal interplay between epidemic disease and political economy in the early modern period.
