Jeffrey Hass focuses on the Nazi blockade of Leningrad in the Second World War. By comparison with the other studies included in this section, Hass shows what fragility and resilience can look like in a more localized society during a more compressed time period. Examining innovations at the meso- and micro-levels of the social system, Hass identifies some key ways in which resilience was fostered. He explores how a city, cut off from the world through an exogenous force, largely maintained its sense of order and resisted collapse.
