In the 1970s, American Sociologist Mark Granovetter posited a theory of social action based on what he called ‘weak ties’. Granovetter argued that the strength of community and social movements comes from the amount of interaction they have with each other. He used the example of two American neighbourhoods, one white working-class (WWC) and one Italian, who were trying to resist redevelopment of their area. He observed that in the WWC neighbourhood, everyone worked in the same factories, drank in the same pubs, attended the same events etc. In contrast, the Italian neighbourhood was based primarily on strong familial relationships, with little interaction between families. In the end, the WWC neighbourhood were able to form a strong community resistance based upon the pre-existing ties between workers and friends and succeeded in protecting their area. In contrast, the Italians were never able to agree on who should be leaders of the movement and could not organise, and they lost their fight.
